CCSP 2026 Flashcards: August Exam Outline Review
A 340-card, six-domain review for the CCSP outline effective August 1, 2026, including cloud AI/ML, dataset, model, and LLM application security.
このデッキについて
This 340-card deck reviews all six domains in the English CCSP exam outline effective August 1, 2026: Cloud Concepts, Architecture and Design; Cloud Data Security; Cloud Platform and Infrastructure Security; Cloud Application Security; Cloud Security Operations; and Legal, Risk and Compliance.
What you'll retrieve
- Separate cloud service, deployment, architecture, data, identity, assurance, operations, risk, privacy, audit, and contract concepts that are easy to confuse.
- Map customer, provider, security, data, privacy, audit, incident, and vendor roles to their primary responsibility boundary.
- Choose a practical control for a short cloud scenario, then state the risk or failure mode it chiefly addresses.
- Make focused architecture, lifecycle, recovery, testing, monitoring, service-management, and outsourcing decisions from stated requirements, including service-level management, availability management, Quality Assurance, audit planning, and provider-risk assessment.
- Recognize revised AI and ML concerns across cloud threat detection, dataset and model privacy, data and model poisoning, provenance, model inversion and extraction, human oversight, and LLM application risks.
Selected reverse and contrast prompts are included where they improve retrieval, such as elasticity versus scalability, portability versus interoperability, RTO versus RPO, hashing versus encryption, controller versus processor, IDS versus IPS, and incident versus problem management. The deck does not mechanically reverse every fact.
Exam-format multiple choice, memorized answer patterns, dumps, vendor-console trivia, copied course wording, and legal advice are excluded. The cards do not reproduce real or simulated ISC2 exam items. They also stay outside deep cryptographic mathematics, product-specific implementation recipes, and specialist AI research that does not change a cloud-security control decision.
The order is deliberate. Each domain advances through short, coherent topic tracks from prerequisite concepts and responsibility boundaries to controls and applied decisions. The final 340-card sequence was reviewed as one topic-progressive order, with identified forward, reverse, near-duplicate, and answer-cue variants deliberately separated to reduce short-range cueing. Its topic tracks are interleaved so the sequence does not become a concept run followed by role, control, and decision runs. Domain 1 establishes cloud characteristics, actors, service and deployment models, secure design, provider evidence, and AI governance. Domain 2 follows data through flows, storage, protection, discovery, classification, rights, retention, evidence, and dataset or model risk. Domains 3 and 4 apply those foundations to infrastructure, resilience, secure development, software supply chains, APIs, LLM applications, and IAM. Domains 5 and 6 close with secure operations, monitoring, incident response, forensics, law, privacy, audit, enterprise risk, and contracts.
Reviewed for the CCSP outline effective August 1, 2026. Coverage was bounded by the official English exam outline PDF, the ISC2 outline page, and ISC2's June 2026 revision notice. NIST and OWASP primary publications were used to check standard control and AI/application-security distinctions.
Every prompt, answer, explanation, sequence choice, and metadata field was independently written from common cloud-security knowledge. The CC0 label applies to that original expression, organization, metadata, and generated cover to the extent applicable rights exist; it does not claim ownership of facts, standards, certification marks, or third-party material.

このデッキのカード
カード 1
質問
What makes a computing environment a cloud rather than ordinary hosted infrastructure?
回答
It provides shared, configurable resources on demand with rapid provisioning and minimal provider interaction. A hosted server without those operating characteristics is not automatically a cloud.
カード 2
質問
What is the security significance of broad network access?
回答
Services are reachable through standard network mechanisms from varied clients. That reach increases the need for strong identity, transport protection, and endpoint-aware access.
カード 3
質問
How do resource pooling and multi-tenancy differ?
回答
Resource pooling dynamically assigns shared capacity; multi-tenancy lets multiple customers use that shared environment with logical isolation. Pooling is the allocation model, while multi-tenancy is the customer-sharing model.
カード 4
質問
What separates elasticity from scalability?
回答
Elasticity adjusts capacity with demand; scalability is the ability to handle growth by adding or changing capacity. Elasticity stresses timely adjustment, often in both directions.
カード 5
質問
What does measured service provide?
回答
Metered visibility into resource consumption. The measurements support billing, capacity decisions, anomaly detection, and accountability.
カード 6
質問
What does on-demand self-service let a cloud customer do?
回答
Provision needed capabilities without waiting for a provider employee. Policy and quota controls can still constrain the request.
カード 7
質問
What does virtualization contribute to cloud computing?
回答
It abstracts physical resources into isolated, assignable compute, storage, or network units. Orchestration turns those units into an on-demand service.
カード 8
質問
What remains the cloud customer's responsibility in every service category?
回答
Governing its identities, data, configuration choices, and lawful use. The exact technical boundary changes, but accountability does not vanish when infrastructure is outsourced.
カード 9
質問
What does a cloud service broker add?
回答
Intermediation, aggregation, or management across cloud services. A broker may compare, combine, or govern services without owning their underlying infrastructure.
カード 10
質問
What is a regulator's cloud-security role?
回答
Set or enforce legal and regulatory obligations that apply to the service and its data. The customer must map those duties into provider selection, controls, and evidence.
カード 11
質問
What is the cloud service provider's core responsibility?
回答
Deliver the contracted cloud capabilities and secure the layers assigned to it. The service model and contract define the boundary.
カード 12
質問
What is orchestration in a cloud environment?
回答
Coordinated automation of provisioning, configuration, scaling, and lifecycle actions across resources. It applies policy consistently across many components.
カード 13
質問
What capability does SaaS give the customer?
回答
Use of a provider-run application. The customer mainly manages users, data, and allowed configuration rather than the platform beneath it.
カード 14
質問
Which four deployment models does NIST SP 800-145 define?
回答
Public, private, community, and hybrid cloud. Multi-cloud describes using more than one cloud provider or service environment; it is distinct from NIST's canonical four-model taxonomy.
カード 15
質問
How do portability and interoperability differ?
回答
Portability moves a workload or data between environments; interoperability lets different environments exchange and use information or services. One reduces switching friction, while the other supports cooperation.
カード 16
質問
What does a cloud service partner do?
回答
Supports or enhances cloud service delivery, use, or assurance. Examples include auditors, integrators, and developers acting beside the customer and provider.
カード 17
質問
Who controls user entitlements inside a SaaS tenant?
回答
The customer organization. The provider supplies the application and access mechanisms, but the customer decides which of its users need which privileges.
カード 18
質問
When is hybrid cloud a better description than multi-cloud?
回答
When the architecture deliberately combines distinct private and public environments. Multi-cloud focuses on using multiple cloud services or providers and may contain no private cloud.
カード 19
質問
What problem does confidential computing address?
回答
Protection of data while it is being processed. Hardware-backed trusted execution environments reduce exposure to the host or platform layer, but do not replace application controls.
カード 20
質問
When does blockchain add useful assurance to a cloud workflow?
回答
When multiple parties need a shared, tamper-evident record without relying on one writer. It does not make source data true, private, lawful, or immune to key and smart-contract failures.
カード 21
質問
When does edge computing improve resilience but complicate security?
回答
When local processing reduces central latency or dependency while distributing data, software, and physical exposure. The decision needs remote attestation, patching, inventory, and failure handling.
カード 22
質問
What does reversibility require in a cloud design?
回答
A practical way to exit or change providers while recovering data, configurations, dependencies, and needed evidence. A theoretical export button is not enough if the result cannot be used elsewhere.
カード 23
質問
What is the first security question before connecting IoT devices to a cloud service?
回答
Can each device be uniquely identified, updated, constrained, and monitored throughout its lifecycle? Cheap connectivity does not offset unmanaged device risk.
カード 24
質問
What capability does PaaS give the customer?
回答
Deployment of customer applications onto a provider-managed platform. The provider runs the underlying infrastructure and runtime, while the customer secures code, data, and configuration.
カード 25
質問
What is a practical cloud decision for quantum-related cryptographic risk today?
回答
Inventory cryptographic dependencies and design for algorithm agility. Replace algorithms according to authoritative migration guidance rather than adopting unreviewed schemes.
カード 26
質問
Which SLA measure is useful only when paired with a clear measurement method and remedy?
回答
Any availability or performance target. Define the service boundary, observation window, exclusions, data source, notification, and remedy before treating the number as assurance.
カード 27
質問
How should a team use a Well-Architected pattern, SANS security principles, or CSA enterprise architecture?
回答
As structured design input mapped to the workload's risks, responsibilities, and evidence. A named framework guides decisions but does not prove that the resulting architecture is secure.
カード 28
質問
What does a FIPS 140 validation establish?
回答
That a named cryptographic module was validated against the stated standard and boundary. It does not prove the surrounding application uses the module safely.
カード 29
質問
Who normally patches the managed runtime in PaaS?
回答
The cloud provider. The customer still owns secure application code, dependencies it supplies, data, identities, and configuration.
カード 30
質問
Who should approve a cloud data classification?
回答
The accountable data owner. Security and privacy teams advise, while custodians implement the handling controls.
カード 31
質問
What should the cloud architect own in secure design?
回答
The documented trust boundaries, security requirements, resilience choices, and responsibility mapping. Operations and product teams then implement and test those decisions.
カード 32
質問
What does DevSecOps change about security ownership?
回答
It makes security a shared, automated part of delivery rather than a final external gate. Product teams still need independent challenge for high-risk decisions.
カード 33
質問
Which controls reduce container escape impact?
回答
Hardened runtimes, minimal privileges, trusted images, isolation boundaries, and prompt patching. Treat a container as a process boundary, not automatically as a security boundary equal to a separate host.
カード 34
質問
Who should own a cloud service's business recovery requirements?
回答
The business or service owner. Technical teams translate the owner's impact tolerance into RTO, RPO, architecture, and tests.
カード 35
質問
What capability does IaaS give the customer?
回答
Provisioning of fundamental compute, storage, and network resources. The customer usually controls operating systems, workloads, and many network settings.
カード 36
質問
Which key-management design limits a cloud provider compromise from exposing customer data?
回答
Separate data from independently controlled encryption keys where the threat model requires it. Access policy, rotation, backup, and recovery for those keys matter as much as their location.
カード 37
質問
What is the safer identity pattern for a cloud workload?
回答
A short-lived, narrowly scoped workload identity. It avoids embedded long-lived credentials and supports rotation and traceability.
カード 38
質問
When can cryptographic erase sanitize cloud data?
回答
When destroying the correct encryption key makes all protected copies computationally unreadable and the encryption implementation is trustworthy. Key copies, snapshots, and replicas must be in scope.
カード 39
質問
What is the first network control for limiting east-west movement between cloud workloads?
回答
Explicit segmentation with deny-by-default rules. Identity-aware policy and traffic telemetry strengthen the boundary; geofencing can add a location condition but cannot replace it.
カード 40
質問
Who normally patches a guest operating system in IaaS?
回答
The cloud customer. The provider secures the underlying facilities and virtualization layer, while the customer manages the guest unless a separate managed service changes that boundary.
カード 41
質問
What is the most important permission control for a serverless function?
回答
A dedicated least-privilege execution identity. Also restrict triggers, secrets, outbound access, and runtime duration; ephemeral execution does not erase external logs, queues, or data.
カード 42
質問
How does immutable infrastructure reduce configuration drift?
回答
Replace changed instances from a controlled image instead of repairing them in place. The image pipeline, secrets, and state stores still need protection.
カード 43
質問
What turns a security baseline into an operating control?
回答
Automated assessment plus timely remediation of deviations. A baseline document alone does not prevent drift.
カード 44
質問
What control keeps protection aligned as cloud data moves through its lifecycle?
回答
Lifecycle-aware policy tied to classification and ownership. Access, encryption, retention, monitoring, and disposal should change with the data's state and purpose.
カード 45
質問
What makes a cloud recovery plan credible?
回答
Regular restore, failover, dependency, and failback tests against business targets. A provider's availability claim does not prove the customer's service can recover.
カード 46
質問
What evidence should be checked first when evaluating a cloud provider?
回答
Evidence mapped to the organization's own requirements and risk criteria. Certifications help only when their scope, period, system, and exceptions cover the intended service.
カード 47
質問
What should drive a cloud BC/DR design before products are selected?
回答
A business impact analysis. It identifies critical services, dependencies, impact over time, and acceptable recovery targets.
カード 48
質問
Who is accountable for approving an AI model's intended cloud use?
回答
The designated AI or business system owner. Model builders provide evidence, while risk, security, privacy, and legal roles challenge the use against policy.
カード 49
質問
What should be tested before accepting a provider's portability claim?
回答
Export the data and configuration, rebuild elsewhere, and measure missing features, time, cost, and dependencies. Contract wording alone cannot prove reversibility.
カード 50
質問
What control most directly reduces hypervisor compromise risk for a customer?
回答
Use a provider with strong isolation assurance, rapid patching, and evidence for the virtualization layer. The customer cannot harden a provider-managed hypervisor directly.
カード 51
質問
How should CBA and ROI inform a cloud recovery design after the BIA?
回答
CBA compares each option's lifecycle cost with expected benefit; ROI expresses the expected return relative to investment. Neither overrides mandatory duties or the BIA's approved impact tolerance.
カード 52
質問
What control helps validate training or detection data before AI use?
回答
Provenance, integrity checks, schema checks, and approval for the intended source. Statistical anomaly checks can add evidence but should not replace ownership.
カード 53
質問
What is the human reviewer's role in AI-assisted security operations?
回答
Validate consequential findings and actions before relying on them. Automation can rank and enrich signals, but the accountable human handles ambiguity and impact.
カード 54
質問
Why read an assurance report's scope before relying on its conclusion?
回答
The report may exclude the exact service, region, control, subservice, or period you need. Assurance cannot be extended beyond its stated boundary.
カード 55
質問
Which controls make model extraction harder at a cloud API?
回答
Strong access control, rate and budget limits, query monitoring, response minimization, and abuse detection. No single control removes the risk from a publicly queryable model.
カード 56
質問
Why is high predictive accuracy insufficient for a cloud data-science or AI model?
回答
The use can still create unacceptable legal, privacy, fairness, security, safety, or operational risk. Accuracy is one quality measure, not automatic authorization to deploy.
カード 57
質問
How should SOAR handle a high-impact containment action?
回答
Use explicit authorization, bounded playbooks, and human approval when impact or uncertainty is high. Automation should be reversible and fully logged.
カード 58
質問
When is Common Criteria evidence relevant to provider evaluation?
回答
When a specific evaluated product and assurance target match the component and threat being assessed. It does not certify an entire cloud service by association.
カード 59
質問
Which data lifecycle sequence is useful for cloud control planning?
回答
Create, store, use, share, archive, and destroy. Real data may move between phases, but each transition needs an owner and handling rule.
カード 60
質問
What is data dispersion in cloud computing?
回答
The distribution of data and copies across systems, regions, media, services, and providers. Replicas, caches, logs, snapshots, and backups all expand the control boundary.
カード 61
質問
What does a cloud data flow describe?
回答
Where data originates, moves, is transformed, is stored, and exits. A useful flow also names trust boundaries, actors, purposes, and protections.
カード 62
質問
How do object and volume storage differ?
回答
Object storage addresses data as objects with metadata; volume storage presents block-like storage to a host. Their access paths, sharing models, snapshots, and permission risks differ.
カード 63
質問
How does ephemeral storage differ from long-term storage?
回答
Ephemeral storage is tied to a short-lived workload or execution; long-term storage is designed to persist independently. Ephemeral does not mean automatically sanitized.
カード 64
質問
What is raw data storage?
回答
Storage of collected data before full cleaning, transformation, or enrichment. Its broad content and uncertain quality make isolation, discovery, provenance, and access control especially important.
カード 65
質問
What makes a data-flow map useful for control design?
回答
It names sources, destinations, transformations, actors, purposes, trust boundaries, and protections. Update it when architecture or processing changes.
カード 66
質問
What should decide whether data may move to another cloud region?
回答
Classification, purpose, residency and transfer rules, contract terms, threat model, and required controls. Region availability alone is not authorization.
カード 67
質問
Which storage type fits immutable, widely shared blobs better than a mounted transactional filesystem?
回答
Object storage. Use volume storage when the workload needs block-style filesystem or database access semantics.
カード 68
質問
A short-lived AI training node is terminated. Why can data risk remain?
回答
Ephemeral compute can leave snapshots, caches, logs, attached volumes, or provider-level remnants. Verify the full storage and key lifecycle, not only instance deletion.
カード 69
質問
What control exposes unknown cloud data stores before they bypass policy?
回答
Continuous asset and data discovery across accounts, regions, services, and shadow paths. Findings need ownership and remediation, not just inventory.
カード 70
質問
What security property does encryption primarily provide?
回答
Confidentiality against parties without the key. Integrity and authenticity require an appropriate authenticated mode or separate mechanism.
カード 71
質問
What does tokenization do?
回答
Replaces sensitive data with a non-sensitive token whose mapping is protected separately. The token can preserve application format while reducing where original data appears.
カード 72
質問
How do structured, semi-structured, and unstructured data differ?
回答
Structured data follows a fixed schema, semi-structured data carries flexible labels or structure, and unstructured data lacks a consistent field model. Discovery needs techniques suited to each form.
カード 73
質問
What is data masking?
回答
A transformation that hides selected data while preserving a usable shape or view. Reversible or weak masking is not anonymization.
カード 74
質問
What does Data Loss Prevention monitor or restrict?
回答
Sensitive-data movement or use across selected channels. DLP depends on discovery, classification, context, coverage, and tuned response.
カード 75
質問
What security property does a cryptographic hash support?
回答
Integrity by detecting change. A plain hash does not hide the input, prove who created it, or prevent guessing of low-entropy values.
カード 76
質問
What does Information Rights Management add beyond storage permissions?
回答
Persistent usage rules attached to protected content, such as view, print, copy, expiry, or revocation. Enforcement still depends on trusted identities, clients, and key services.
カード 77
質問
Where should application secrets be kept?
回答
In a managed secret store with narrow access, audit logs, rotation, and short-lived retrieval. Source code, images, and general configuration files are poor secret stores.
カード 78
質問
What is anonymization trying to achieve?
回答
Make data no longer reasonably linkable to an identifiable person. Re-identification risk must be assessed against auxiliary data and the release context.
カード 79
質問
Why separate key-custodian duties from data administration?
回答
To reduce the chance that one person can both reach ciphertext and independently unlock it. Separation of duties should also cover recovery and emergency access.
カード 80
質問
What control reduces dependence on provider-held encryption keys?
回答
Customer-controlled keys with independent policy and lifecycle management. The choice adds recovery, availability, rotation, and administrator risks that must be designed explicitly.
カード 81
質問
How can tokenization reduce exposure in an application database?
回答
Store tokens in routine workflows and isolate the token vault or mapping service. Access to detokenization should be rarer and more tightly logged.
カード 82
質問
How can a hash support evidence integrity?
回答
Record a strong hash at acquisition and verify it after each transfer or analysis step. Chain-of-custody records explain who handled the evidence and why.
カード 83
質問
What is the safer source for non-production test data?
回答
Synthetic or appropriately transformed data that meets the test need without exposing production identities. Validate re-identification risk before release.
カード 84
質問
What makes DLP enforcement practical instead of noisy?
回答
Accurate discovery and classification, contextual rules, staged response, tuned exceptions, and incident ownership. Blocking every pattern match can disrupt work without reducing real leakage.
カード 85
質問
What enables IRM revocation after a file leaves its original repository?
回答
A trusted client that checks current rights and can no longer obtain the needed key or license. Offline copies and screenshots remain boundary cases.
カード 86
質問
How should cloud data discovery handle false positives?
回答
Route uncertain matches for risk-based validation and tune detection with evidence. Silently discarding them hides coverage gaps; blocking them all creates operational failure.
カード 87
質問
What keeps certificates trustworthy after issuance?
回答
Inventory, protected private keys, renewal, revocation, validation, and monitored expiry. Issuing a certificate is only the start of its lifecycle.
カード 88
質問
What is envelope encryption?
回答
Encrypt data with a data-encryption key, then protect that key with a separate key-encryption key. Rotating or rewrapping the key-encryption key can protect existing data-encryption keys without re-encrypting payload data; replacing a data-encryption key may require payload re-encryption.
カード 89
質問
What is data classification?
回答
Assignment of a sensitivity or business category that drives handling requirements. The category should reflect impact, law, contract, and business need.
カード 90
質問
When is tokenization preferable to ordinary encryption?
回答
When workflows can use a surrogate while original values stay in a tightly isolated mapping service. Encryption is better when authorized systems must recover data directly with keys.
カード 91
質問
Should a password be encrypted or hashed for verification?
回答
Hash it with a password-specific salted, slow derivation function. Reversible encryption creates unnecessary recovery of the original password.
カード 92
質問
When is masking insufficient for a public dataset release?
回答
When remaining fields or external data can reasonably re-identify people. Public release needs a defensible anonymization assessment, not cosmetic redaction.
カード 93
質問
Why should DLP not be the only control against cloud exfiltration?
回答
It sees only covered channels and recognized content. Least privilege, segmentation, egress control, encryption, monitoring, and response reduce gaps.
カード 94
質問
When is IRM more useful than a repository access control list?
回答
When usage restrictions must follow a file beyond the original repository. If data never leaves a controlled service, native authorization may be simpler and stronger.
カード 95
質問
Why perform discovery before broad classification enforcement?
回答
You need to know what data exists and where it lives before applying reliable labels and controls. Enforcement on an incomplete inventory leaves blind spots.
カード 96
質問
What should trigger data reclassification?
回答
A change in content, use, law, contract, business impact, aggregation, or identifiability. Review should also occur on a defined schedule.
カード 97
質問
Why rotate encryption keys?
回答
To limit exposure, meet policy, and replace keys after age, role, algorithm, or compromise changes. Rotation must preserve authorized access to older data until it is safely reprotected or retired.
カード 98
質問
Who sets a cloud dataset's business classification?
回答
The accountable data owner. Automated tools can propose labels, but the owner resolves business context and exceptions.
カード 99
質問
How does a data label differ from a classification policy?
回答
The label marks a specific asset; the policy defines what the category means and how it must be handled. Labels without enforcement are only metadata.
カード 100
質問
What is a data steward responsible for?
回答
Day-to-day quality, definition, and policy consistency for data. A steward supports the owner but does not replace the owner's accountability.
カード 101
質問
How do retention and archiving differ?
回答
Retention states how long data must or may be kept; archiving moves data into a managed long-term state. Archived data remains subject to access, integrity, discovery, and deletion rules.
カード 102
質問
What does a data controller decide?
回答
The purposes and essential means of processing personal data. The exact legal definition depends on the applicable law.
カード 103
質問
When should a derived dataset inherit its source classification?
回答
By default, until an accountable owner proves the transformation changed sensitivity. Aggregation can reduce or increase risk depending on content and linkability.
カード 104
質問
How should classification labels affect cloud controls?
回答
Drive access, encryption, sharing, location, retention, monitoring, and deletion policy. Enforcement should follow the label across supported copies and transformations.
カード 105
質問
What does a legal hold do?
回答
Suspends normal deletion for information relevant to a legal or regulatory matter. It preserves authorized access and evidence until the hold is released.
カード 106
質問
What should a privacy role contribute to cloud data design?
回答
Purpose, minimization, transparency, rights, transfer, retention, and impact requirements. Security protects data, while privacy also asks whether processing should occur and under what conditions.
カード 107
質問
What control turns a retention schedule into repeatable cloud behavior?
回答
Policy-driven lifecycle automation with holds, approvals, exceptions, and audit evidence. Automation must cover replicas and backups where the platform supports it.
カード 108
質問
What is a data custodian responsible for?
回答
Implementing and operating the technical handling controls. Storage, backup, access, logging, and deletion are typical custody duties.
カード 109
質問
Who should own the retention schedule?
回答
The records or information-governance function with legal and business input. Technology teams implement the approved schedule and evidence.
カード 110
質問
What does a data processor do?
回答
Processes personal data for a controller under documented instructions. Using the data for its own new purpose may change the role and obligations.
カード 111
質問
What proves a cloud deletion request was completed responsibly?
回答
Provider and customer evidence tied to the asset, method, scope, time, and remaining copies. A successful API response alone may not cover backups, replicas, or exported data.
カード 112
質問
Which controls protect a long-term cloud archive?
回答
Restricted access, durable integrity checks, format and key preservation, redundancy, retention policy, and tested retrieval. An archive that cannot be read or trusted has failed its purpose.
カード 113
質問
Who should approve a training dataset and model version for production?
回答
The accountable model or system owner using evidence from data, security, privacy, and validation roles. Approval must bind the exact versions and intended use.
カード 114
質問
Which event fields most often establish accountability for cloud data access?
回答
Trusted identity, action, target, result, timestamp, source context, and relevant network or location data. Collect only attributes needed for the security, legal, and privacy purpose.
カード 115
質問
Why synchronize clocks across cloud evidence sources?
回答
To correlate events into a defensible timeline. Record time source, zone, drift, and collection context when precision matters.
カード 116
質問
Which risk is present when model outputs reveal features of sensitive training records?
回答
Model inversion or related privacy inference. Data minimization, privacy testing, output controls, and access limits reduce exposure.
カード 117
質問
Who authorizes and scopes a legal hold?
回答
An authorized legal or records function. Cloud administrators implement it without deciding the legal scope themselves.
カード 118
質問
What must AI dataset validation check besides file integrity?
回答
Source authority, consent or permitted use, representativeness, quality, labeling, poisoning indicators, and intended-use fit. A matching checksum only proves the bytes did not change after that checkpoint.
カード 119
質問
Why is an archive not a substitute for a recovery backup?
回答
An archive optimizes long-term preservation and retrieval; a backup supports restoration after loss or corruption. One system can sometimes serve both only if it meets both control sets and tests.
カード 120
質問
What protects AI dataset and model provenance?
回答
Versioned inventories, signed or hashed artifacts, controlled pipelines, approval records, and lineage from source to deployment. Bind validation results to the exact artifact versions.
カード 121
質問
Which context should be omitted from a data event log?
回答
Data that is unnecessary for the defined security, accountability, or legal purpose. More logging can create privacy, cost, and breach risk without improving evidence.
カード 122
質問
What happens when a valid legal hold conflicts with scheduled deletion?
回答
The authorized hold suspends deletion for the in-scope data. Keep access limited, document the exception, and resume policy when the hold is released.
カード 123
質問
What adds non-repudiation evidence beyond a plain event log?
回答
Strong identity binding, protected timestamps, integrity controls, and controlled custody. The strength depends on the whole evidence process, not a single hash field.
カード 124
質問
What privacy question does a membership-inference attack answer?
回答
Whether a particular record was likely part of a model's training data. Limit exposed confidence, query abuse, overfitting, and unnecessary sensitive training data.
カード 125
質問
What is the clearest sign that training-data poisoning controls failed?
回答
Untrusted or manipulated examples changed model behavior or inserted a hidden trigger. Investigate provenance, pipeline access, validation, and the exact affected versions.
カード 126
質問
What is the strongest first step when an AI use case asks for every available customer field?
回答
Reduce collection to data necessary for the approved purpose. Minimization lowers privacy, poisoning, access, retention, and breach exposure before technical controls are added.
カード 127
質問
What is the cloud network team's primary security role?
回答
Implement approved segmentation, routing, edge protection, secure connectivity, and network telemetry. Application teams still define workload access needs.
カード 128
質問
Which layers make up a cloud infrastructure trust stack?
回答
Physical facilities, network, compute, storage, virtualization, and management services. A workload inherits dependencies and failure modes from every layer beneath or beside it.
カード 129
質問
How do the management plane and data plane differ?
回答
The management plane configures and governs resources; the data plane carries or processes workload traffic and data. Compromise of the management plane can change many data-plane controls at once.
カード 130
質問
What is a trust boundary in cloud architecture?
回答
A point where identity, control, ownership, or assurance changes. Data crossing it needs an explicit policy, validation, and protected channel.
カード 131
質問
Who owns a customer's cloud network and identity configuration?
回答
The customer for the configuration choices it controls. Provider defaults and guardrails help, but do not approve the customer's architecture.
カード 132
質問
What logical control prevents one tenant from reaching another tenant's resources?
回答
Enforced tenant partitioning across identity, network, compute, storage, and management paths. Test the negative boundary, not only valid access.
カード 133
質問
Why is the cloud management plane a high-value target?
回答
It can create, modify, expose, or destroy many resources through one privileged interface. Protect it more strongly than routine workload access.
カード 134
質問
What limits lateral movement after one cloud workload is compromised?
回答
Microsegmentation with identity-aware, least-privilege communication policy. Monitor denied and unusual flows to find attempted spread.
カード 135
質問
How does infrastructure as code improve control assurance?
回答
It makes configuration reviewable, repeatable, testable, and traceable. Protect the repository, pipeline, state, modules, and deployment identity.
カード 136
質問
How should a team verify an infrastructure control still works?
回答
Test its intended outcome with current evidence and representative failure or attack conditions. Configuration presence alone does not prove effectiveness.
カード 137
質問
What security boundary should virtualization create between tenants?
回答
Strong isolation of compute, memory, storage, network, and management operations. Shared hardware still creates side-channel, escape, and noisy-neighbor considerations.
カード 138
質問
Which controls should protect cloud management-plane access?
回答
Phishing-resistant MFA, privileged access management, separate admin identities, conditional access, least privilege, and immutable logging. Restrict source networks where practical.
カード 139
質問
How do type 1 and type 2 hypervisors differ?
回答
A type 1 hypervisor runs directly on hardware; a type 2 hypervisor runs on a host operating system. The extra host layer changes attack surface and operational use.
カード 140
質問
Who secures the public cloud facility and physical host?
回答
The cloud provider. Customers still evaluate the provider's physical assurance and design their service around disclosed locations and failure domains.
カード 141
質問
What protects a cloud AI training cluster from unrelated tenant traffic?
回答
Dedicated identities, microsegmentation, controlled data paths, hardened images, and monitored management access. Accelerator scheduling and storage paths belong in the boundary.
カード 142
質問
When is packet capture useful in cloud infrastructure?
回答
When network-level detail is needed and collection is lawful, technically available, scoped, and protected. Flow logs may be safer and sufficient for many investigations.
カード 143
質問
Which control protects detached cloud volumes and snapshots?
回答
Encryption with governed keys plus explicit access policy. Inventory and delete orphaned copies because detachment does not remove their data.
カード 144
質問
Why correlate infrastructure logs across layers?
回答
To connect identity, management, network, host, and workload events into one incident path. Preserve original records and normalization context.
カード 145
質問
What is a platform owner's responsibility for tenant isolation?
回答
Configure, patch, monitor, and test the shared platform so one workload cannot cross its authorized boundary. Consumers must use the platform's isolation features correctly.
カード 146
質問
When should an AI training cluster use stronger isolation than ordinary batch compute?
回答
When valuable models, sensitive datasets, untrusted code, or high-cost accelerators raise confidentiality, integrity, or exhaustion risk. Match isolation to the workload threat model.
カード 147
質問
What does an HSM protect in cloud infrastructure?
回答
Cryptographic keys and operations inside a hardened, policy-controlled boundary. An HSM does not decide whether the requesting workload is authorized unless surrounding policy enforces it.
カード 148
質問
What is a failure domain?
回答
A set of components likely to fail together because they share a dependency. Regions, zones, racks, power feeds, control services, or software versions can define one.
カード 149
質問
A volume is deleted but its snapshots remain. Is the data gone?
回答
No. The snapshots are separate retained copies. Apply inventory, retention, hold, encryption-key, and deletion policy to every snapshot and replica.
カード 150
質問
How should a platform reduce virtualization escape risk?
回答
Minimize and patch the virtualization stack, isolate management interfaces, restrict device exposure, monitor anomalies, and contain workloads by risk. Stronger workload boundaries may be needed for hostile tenants.
カード 151
質問
What is the first response to an internet-exposed cloud management endpoint?
回答
Remove unnecessary public reachability, then enforce strong identity and monitored privileged access. A hidden URL or uncommon port is not a control.
カード 152
質問
What is the facilities team's role in a private cloud data center?
回答
Operate physical access, power, cooling, fire protection, and environmental monitoring. Security requirements should define evidence and escalation for those systems.
カード 153
質問
Which site-location condition creates direct legal exposure for a cloud workload?
回答
The jurisdictions that can reach the facility, operator, customers, or data. Cost, hazards, utilities, connectivity, workforce, and physical threats require separate location analysis.
カード 154
質問
How does diverse pathway connectivity improve resilience?
回答
It prevents one cable route, conduit, carrier handoff, or excavation from cutting every link. Verify physical diversity rather than relying on different circuit names.
カード 155
質問
When does building a private data center make more sense than buying cloud capacity?
回答
When requirements for control, latency, sovereignty, specialized hardware, or long-term economics outweigh the build and operating burden. Compare full lifecycle cost and resilience, not purchase price alone.
カード 156
質問
Which physical controls protect cloud hardware from unauthorized handling?
回答
Zoned access, least privilege, identity checks, surveillance, visitor controls, alarms, and custody records. The strength should match asset and data impact.
カード 157
質問
What power design reduces a data center's single-point risk?
回答
Independent feeds, conditioned distribution, UPS capacity, generators, fuel plans, and tested transfer. Maintenance paths must preserve the intended redundancy.
カード 158
質問
What should environmental monitoring detect in a data center?
回答
Temperature, humidity, airflow, water, smoke, power, and equipment conditions that threaten service. Alerts need thresholds, escalation, and tested response.
カード 159
質問
How does resilience differ from simple redundancy?
回答
Redundancy adds alternatives; resilience keeps or restores acceptable service despite disruption. Redundant components can still share one failure domain or bad configuration.
カード 160
質問
Which on-premises physical control remains a customer duty when workloads move to public cloud?
回答
Protection of customer-controlled offices, endpoints, network links, and any retained equipment. The provider's data-center controls do not secure the customer's physical environment.
カード 161
質問
What are the core outputs of an infrastructure risk assessment?
回答
Prioritized risks tied to assets, threats, vulnerabilities, likelihood, impact, existing controls, and owners. The output should lead to treatment and follow-up.
カード 162
質問
Who may accept residual infrastructure risk?
回答
The authorized business risk owner, not the engineer who found it. Acceptance should state scope, duration, rationale, and review trigger.
カード 163
質問
How do a threat, vulnerability, and risk differ?
回答
A threat can cause harm, a vulnerability is a weakness it may exploit, and risk combines uncertain harm with business impact. A weakness without relevant exposure may be lower priority.
カード 164
質問
What reveals that two supposedly redundant cloud systems share fate?
回答
They depend on the same control plane, account, region, identity service, network path, software defect, operator, or key. Model those dependencies before counting redundancy.
カード 165
質問
What does a security control owner do?
回答
Ensures an assigned control is designed, implemented, evidenced, monitored, and corrected. The role may coordinate several technical operators.
カード 166
質問
Which risk treatment options should a cloud team recognize?
回答
Avoid, mitigate, transfer or share, and accept. Treatment changes exposure or ownership; it does not erase accountability.
カード 167
質問
What is a recovery service level?
回答
The minimum service capacity or functionality that must be restored, often stated as a percentage of normal service. RSL defines how much service must work; RTO sets the time limit, while RPO sets the maximum data-loss interval.
カード 168
質問
What makes a machine image trustworthy for cloud deployment?
回答
Known provenance, minimal contents, current patches, signed or verified integrity, vulnerability results, and controlled promotion. Revalidate it when dependencies age.
カード 169
質問
When do multiple availability zones materially improve resilience?
回答
When the service, data, network, identities, and operations can continue after one zone and its shared dependencies fail. Merely placing instances in two zones is not a tested design.
カード 170
質問
What should determine the strength of an infrastructure security control?
回答
The asset impact, threat, vulnerability, exposure, legal duties, and risk tolerance. Use control frameworks as structured input, not as an automatic one-size baseline.
カード 171
質問
Which layered controls improve availability against cloud DDoS?
回答
Provider edge absorption, rate controls, resilient scaling, caching, WAF or protocol filtering, and an exercised response plan. Scaling alone can turn attack traffic into cost exhaustion.
カード 172
質問
A cloud contract shifts breach costs to a provider. Has the risk been removed?
回答
No. Financial risk may be transferred, while operational, legal, reputational, and customer harm can remain. Retained exposure still needs mitigation and acceptance.
カード 173
質問
Why map dependencies across compute, storage, and network services?
回答
A resilient application can still fail when a shared supporting service fails. Dependency maps expose hidden single points, circular recovery steps, and shared fate.
カード 174
質問
What does RPO constrain in an infrastructure recovery design?
回答
The maximum acceptable data-loss interval measured backward from disruption. It drives backup or replication frequency and consistency choices.
カード 175
質問
What should trigger automated failover?
回答
Reliable health evidence that the primary cannot meet the service objective, with safeguards against split-brain and false triggers. Manual approval may remain appropriate for ambiguous high-impact cases.
カード 176
質問
When is an IPS preferable to an IDS?
回答
When inline blocking is justified, tested, and safe for the traffic and availability requirements. Use detection-only when false positives or inline failure would create unacceptable impact.
カード 177
質問
What makes residual infrastructure risk ready for acceptance?
回答
A clear scenario, affected assets, existing controls, likelihood and impact, owner, duration, alternatives, and review trigger. Vague acceptance is not governance.
カード 178
質問
What makes a cloud backup resistant to account compromise?
回答
Separate administration, immutable or offline retention, encryption, protected deletion, and tested restore. Keep recovery credentials outside the routine production trust path.
カード 179
質問
What does a BC/DR coordinator own during cloud recovery planning?
回答
The cross-team plan, exercises, dependencies, contacts, evidence, and follow-up. Service owners still set business priorities and targets.
カード 180
質問
Which recovery design supports a near-zero RPO?
回答
Synchronous or otherwise strongly consistent replication across independent failure domains, if latency and shared-fate limits are acceptable. Backups still protect against corruption and deletion.
カード 181
質問
Which overlooked dependency can stop users from reaching replicated application servers after failover?
回答
The identity service. Recovery planning should also cover DNS, keys, secrets, routes, data stores, quotas, and external services.
カード 182
質問
Why test restore separately from backup completion?
回答
A completed backup may be corrupt, incomplete, inaccessible, or too slow for the target. Restore testing proves usability and measures recovery performance.
カード 183
質問
Why plan failback before declaring a DR design complete?
回答
Returning to the preferred environment can create another outage, conflict, or data loss. Define authority, synchronization, validation, rollback, and communication.
カード 184
質問
Which design choice most directly supports a short RTO?
回答
Pre-provisioned or rapidly deployable recovery capacity with automated, tested orchestration. Data, identities, network, dependencies, and operators must be ready too.
カード 185
質問
What should application-security awareness change in a cloud team?
回答
Daily design and delivery decisions, not just annual quiz results. Use role-specific OWASP, ASVS, SANS Top 25, and LLM-risk examples as practical boundaries, then reinforce them with real defects.
カード 186
質問
What makes an SDLC a secure SDLC?
回答
Security requirements, design analysis, implementation controls, verification, release evidence, maintenance, and retirement are built into the lifecycle. A final penetration test alone is not a lifecycle.
カード 187
質問
How do functional and non-functional security requirements differ?
回答
Functional requirements specify security behavior; non-functional requirements set qualities such as availability, performance, resilience, or assurance. Both need measurable acceptance criteria.
カード 188
質問
Who turns business needs into testable application security requirements?
回答
The product or business owner with security, privacy, legal, and engineering input. Requirements need an accountable owner and acceptance evidence.
カード 189
質問
How should a security requirement remain visible through delivery?
回答
Trace it to design decisions, code or configuration, tests, approval, and operating evidence. Untraceable requirements are easy to drop during change.
カード 190
質問
What is the purpose of threat modeling?
回答
Identify likely abuse paths and design mitigations before or during development. Keep the model tied to assets, trust boundaries, architecture changes, and evidence.
カード 191
質問
What makes developer security training actionable?
回答
Role-specific examples, secure alternatives, practice in the delivery toolchain, and feedback from real defects. Refresh it as platforms and threats change.
カード 192
質問
Should agile delivery remove formal security gates?
回答
No. It should make them smaller, earlier, automated where reliable, and tied to risk. High-impact changes can still require independent approval.
カード 193
質問
Which cloud-specific application risks need explicit SDLC decisions before coding?
回答
Shared-technology exposure, provider insiders, limited visibility or control, and legal or jurisdiction boundaries. Record the provider boundary, evidence, data location, isolation, and compensating controls.
カード 194
質問
How do federation and SSO differ?
回答
Federation establishes trust across identity domains; SSO lets a user authenticate once for multiple services. Federation can enable SSO, but the concepts are not identical.
カード 195
質問
What is a developer's responsibility in secure cloud delivery?
回答
Use approved patterns, validate inputs and outputs, protect secrets, handle errors safely, review dependencies, and fix findings. Security tools support that judgment rather than replace it.
カード 196
質問
What should a peer security reviewer verify?
回答
That the change preserves requirements, trust boundaries, authorization, data handling, failure behavior, and evidence. Review the actual diff and deployment effect, not only style.
カード 197
質問
What is the application security architect accountable for?
回答
Security patterns, trust boundaries, threat decisions, control integration, and documented exceptions. Teams share implementation, but architecture needs coherent ownership.
カード 198
質問
Which threat categories does STRIDE prompt a team to examine?
回答
Spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege. It is a coverage aid, not a risk score.
カード 199
質問
What secure-coding rule most directly prevents broken object authorization?
回答
Check the current subject's permission for the specific object on every request. ASVS or SAFECode guidance can structure assurance, but hiding identifiers or checking only authentication is insufficient.
カード 200
質問
What should a secret-scanning gate do when it finds a real credential?
回答
Block exposure, revoke or rotate the credential, remove it from reachable history, and investigate use. Deleting the latest line does not invalidate copied history.
カード 201
質問
How does protected version control support software assurance?
回答
It creates tamper-evident, access-controlled history for reviewed code and configuration changes. Protect references from unauthorized rewrite, retain audit logs, control bypass, and bind signed artifacts to approved releases; content-addressed commits alone do not make branch history immutable.
カード 202
質問
Which threat-model method is the simplest checklist for threat categories at trust boundaries?
回答
STRIDE. Use a process-centered method when business impact, attacker paths, and staged analysis need deeper treatment.
カード 203
質問
What is an abuse case?
回答
A description of how an actor could misuse a feature or violate a security goal. It turns attacker intent into testable defensive behavior.
カード 204
質問
Why should a team avoid treating DREAD scores as objective truth?
回答
Its ratings are judgment-based and can create false precision. Document evidence, assumptions, impact, and uncertainty instead of relying on one number.
カード 205
質問
How do SAST and DAST differ?
回答
SAST examines code or compiled artifacts without running the full application; DAST probes a running application from the outside. They find different classes of weakness.
カード 206
質問
What does Software Composition Analysis examine?
回答
Third-party components, versions, licenses, and known vulnerability or policy data. It does not prove that a dependency is safe in context or detect every malicious package.
カード 207
質問
When should a cloud application's threat model be updated?
回答
When trust boundaries, data, identities, dependencies, deployment, features, or threats materially change. Periodic review catches slow drift.
カード 208
質問
How do black-box and white-box security testing differ?
回答
Black-box testing uses external behavior with little internal knowledge; white-box testing uses code, design, or configuration knowledge. Gray-box testing combines partial knowledge with external interaction.
カード 209
質問
What should a CI/CD security gate block?
回答
A defined, evidence-based release condition such as an exposed secret, failed critical control, unapproved artifact, or unacceptable vulnerability. Keep exceptions explicit, owned, and time-bounded.
カード 210
質問
When is PASTA or ATASM more useful than a short threat checklist?
回答
When the team needs a structured path from business objectives and architecture to attacker behavior, attack surfaces, and mitigations. Match method depth to decision risk.
カード 211
質問
Where does SAST provide the earliest useful feedback?
回答
During coding and pull-request review, before deployment. Tune rules, confirm reachability and context, and fix root causes rather than chasing raw counts.
カード 212
質問
When is IAST worth adding to a cloud test pipeline?
回答
When representative automated tests exist and runtime path-to-code insight will improve triage. Without exercised paths, instrumentation has little to observe.
カード 213
質問
How should an application handle LLM output before passing it to a browser, shell, database, or tool?
回答
Treat it as untrusted data and validate, encode, constrain, or approve it for the destination. Model fluency is not a security guarantee.
カード 214
質問
What should an abuse-case test assert for a sensitive workflow?
回答
The application safely rejects or contains a realistic misuse path and leaves useful evidence. Test rate, sequence, privilege, data, and failure-state abuse where relevant.
カード 215
質問
What environment makes DAST results most useful?
回答
A representative running deployment with safe test data, reachable paths, and observable results. Production testing needs explicit authorization and safeguards.
カード 216
質問
Who owns risk from a third-party software component?
回答
The organization that chooses and operates it. The supplier supplies evidence and remediation, but outsourcing the component does not outsource customer accountability.
カード 217
質問
How do an SBOM and SCA work together?
回答
SCA identifies component and policy findings; an SBOM records the released component inventory. Bind both to the exact artifact and update risk when new information appears.
カード 218
質問
What does artifact signing protect in a software supply chain?
回答
Integrity and authenticated provenance of the signed artifact. Verification policy must also trust the signer, build path, and release authorization.
カード 219
質問
What makes open-source software validated for a cloud application?
回答
Its source, release, integrity, dependencies, license, maintenance, vulnerabilities, and intended use have been assessed. Open code is inspectable, not automatically safe.
カード 220
質問
Which cloud application control validates XML message structure before processing?
回答
An XML firewall. A WAF filters web traffic, an API gateway applies API-facing policy, DAM monitors database activity, and a load balancer distributes traffic.
カード 221
質問
What authorization check belongs behind every sensitive API operation?
回答
A server-side decision for the current identity, action, object, tenant, and context. Gateway authentication alone cannot decide application-level ownership.
カード 222
質問
How should an API treat untrusted input?
回答
Validate type, structure, size, range, encoding, and allowed semantics before use. Reject unexpected fields where ambiguity or mass assignment creates risk.
カード 223
質問
What is an Identity Provider responsible for in federation?
回答
Authenticating subjects and issuing trustworthy identity assertions under agreed policy. The relying application still authorizes each requested action.
カード 224
質問
What does sandboxing add to cloud application security?
回答
A constrained execution boundary for untrusted or risky code and content. Restrict identity, network, files, secrets, time, and compute outside the sandbox too.
カード 225
質問
What should block adoption of a third-party software component?
回答
Unacceptable provenance, integrity, vulnerability, maintenance, license, access, or exit risk. Popularity and a clean scan do not settle supplier risk.
カード 226
質問
Which test perspective should verify hidden authorization logic?
回答
White-box review and testing, supported by black-box attempts to cross the boundary. Internal knowledge finds code paths; external tests confirm observable enforcement.
カード 227
質問
Which practice verifies that a cloud release consistently meets defined quality and security criteria?
回答
Quality Assurance (QA). It plans and tracks repeatable reviews, tests, acceptance evidence, defect handling, and process improvement across delivery.
カード 228
質問
Which IAM controls reduce takeover of a federated cloud account?
回答
Strong MFA, trusted federation configuration, short sessions, conditional access, lifecycle automation, and monitored privilege. Secure both the IdP and relying service.
カード 229
質問
What is the safest response when retrieved content tells an LLM to ignore system rules?
回答
Treat the instruction as untrusted data, preserve higher-priority policy, and prevent unauthorized tool or data access. Input filtering alone cannot eliminate prompt injection.
カード 230
質問
How should an LLM application reduce sensitive information disclosure?
回答
Minimize prompt and training data, enforce retrieval authorization, redact where justified, constrain outputs, and test leakage. A system prompt telling the model to keep secrets is not sufficient.
カード 231
質問
A model repository account is compromised and a backdoored model is published. Which risks overlap?
回答
Supply-chain compromise and data or model poisoning. Pin trusted versions, verify provenance and signatures, scan safely, validate behavior, and control promotion.
カード 232
質問
What identity should one microservice use to call another?
回答
A distinct, short-lived workload identity with least-privilege authorization. Avoid sharing broad static credentials across services.
カード 233
質問
How should an agentic LLM be constrained before it can delete cloud resources?
回答
Give it minimal scoped tools, validate arguments, require approval for destructive actions, enforce budgets, and log every decision and result. Capability should match the smallest authorized task.
カード 234
質問
Should a system prompt be treated as a secret control boundary?
回答
No. Design as if instructions may be exposed. Keep credentials and authorization outside the prompt, minimize sensitive details, and enforce policy in trusted code.
カード 235
質問
What is the main risk of weak authorization in a shared vector store?
回答
Retrieval can cross tenant or user boundaries and expose embeddings, documents, or poisoned context. Partition, authorize, validate provenance, and monitor ingestion and queries.
カード 236
質問
When does a CASB add value beside an IdP?
回答
When the organization needs visibility or policy over cloud-service use, data movement, sessions, or unmanaged access beyond authentication. The IdP establishes identity; the CASB governs selected cloud interactions.
カード 237
質問
How should a high-impact workflow use an LLM answer that may be plausible but false?
回答
Verify it against authoritative data or require qualified human review before action. Communicate uncertainty and preserve source evidence.
カード 238
質問
Which controls address unbounded LLM consumption?
回答
Per-user and per-task quotas, rate limits, token and tool budgets, timeouts, concurrency limits, anomaly alerts, and safe cancellation. Monitor financial as well as availability impact.
カード 239
質問
How do an HSM and a TPM differ?
回答
An HSM protects shared or service cryptographic operations; a TPM anchors trust to one platform. Both protect keys, but their scope and use cases differ.
カード 240
質問
What does secure by default mean for cloud infrastructure?
回答
A new resource starts in the least exposed, least privileged, approved state. Users must make an explicit, reviewed choice to widen access or capability.
カード 241
質問
Why do virtual CPU, memory, storage, and network settings have security impact?
回答
They define resource exposure, isolation, exhaustion limits, and device access. Overbroad virtual hardware can create attack paths or noisy-neighbor risk.
カード 242
質問
Which hypervisor type is usually preferred for production cloud hosts?
回答
A type 1 hypervisor because it removes the general-purpose host OS layer. The actual choice still depends on assurance, patching, management, and workload needs.
カード 243
質問
How can TPM-backed measured boot support cloud host assurance?
回答
Measurements anchor boot components to hardware so an attestation service can compare them with approved state. The decision still depends on trusted reference values and response policy.
カード 244
質問
How should guest OS virtualization tools be installed and maintained?
回答
Use provider-authorized packages, enable only needed features, match supported versions, patch promptly, and monitor their privilege. Remove stale tools that widen the host-to-guest boundary.
カード 245
質問
What is cloud platform operations responsible for after secure build?
回答
Maintaining approved configuration, availability, patching, monitoring, backup, access, and evidence. Operations should feed recurring defects back into design.
カード 246
質問
What does a privileged access administrator control?
回答
The issuance, elevation, monitoring, review, and revocation of administrative access. Separate the access-control role from routine use where practical.
カード 247
質問
What is the safer pattern for remote SSH administration?
回答
Short-lived identity-based access through a controlled path with host verification, least privilege, session logging, and no shared keys. Disable direct root login.
カード 248
質問
When should a cloud workload require platform attestation?
回答
When access depends on proof that the host or confidential environment is in an approved measured state. Define what is measured, who verifies it, and what failure does.
カード 249
質問
Which protocol adds origin authentication and integrity to DNS data?
回答
DNSSEC. TLS protects a transport session, a VPN protects traffic across an untrusted boundary, and DHCP safeguards prevent rogue address or configuration assignment.
カード 250
質問
What should enforce separation between cloud network zones?
回答
Routing and firewall or security-group policy tied to explicit allowed flows. VLANs can organize segments but do not enforce policy by themselves.
カード 251
質問
How do IDS and IPS differ operationally?
回答
An IDS alerts on suspected activity; an IPS sits inline and can block it. Inline prevention adds availability and false-positive risk.
カード 252
質問
What reduces RDP exposure in a cloud environment?
回答
Remove direct internet access, require a hardened gateway or private path, strong MFA, current patches, device checks, and session monitoring. Limit clipboard and drive redirection by need.
カード 253
質問
What makes a honeypot safe enough to operate?
回答
Isolation, no production trust, controlled data, monitored egress, legal approval, and an incident plan. It should observe attackers without becoming their launch point.
カード 254
質問
How do high availability and backup differ?
回答
High availability keeps service running through component failure; backup restores data or state after loss or corruption. One does not replace the other.
カード 255
質問
How should firewall, IDS, and IPS controls be layered?
回答
Firewalls constrain allowed paths, IDS detects suspicious activity, and IPS may block selected attacks inline. Central telemetry and tuned ownership make the layers useful.
カード 256
質問
When is a cloud security group insufficient as the only network control?
回答
When application-aware filtering, centralized inspection, advanced threat detection, or cross-environment policy is required. Keep security groups as workload-level least-privilege boundaries.
カード 257
質問
How should management-plane tools be installed?
回答
From verified sources through a controlled, minimal, hardened build with separate privileged access and logging. Remove sample accounts, unused plugins, and default exposure.
カード 258
質問
What is patch management?
回答
A controlled lifecycle for identifying, prioritizing, testing, deploying, verifying, and documenting security and reliability updates. Asset inventory and exception ownership are prerequisites.
カード 259
質問
How do performance and capacity monitoring differ?
回答
Performance monitoring measures current service behavior; capacity monitoring forecasts whether resources can meet future demand. Both need business thresholds and trends.
カード 260
質問
How do change, release, and deployment management differ?
回答
Change management authorizes and controls modification; release management packages approved capability; deployment management moves it into an environment. One workflow may integrate all three without erasing their goals.
カード 261
質問
What should decide whether an IPS blocks automatically?
回答
Detection confidence, asset criticality, attack impact, false-positive cost, bypass behavior, and rollback. Start with observation when evidence is weak.
カード 262
質問
Who owns a patch exception?
回答
The authorized system or risk owner, with technical evidence from operations and security. The exception needs compensating controls, expiry, and review.
カード 263
質問
What does a capacity manager protect?
回答
The service's ability to meet current and forecast demand within cost and resilience constraints. The role tracks trends, thresholds, quotas, and scaling lead time.
カード 264
