ISC CISSP Practice Test 82
Question 810
An executive travels to a region with elevated kidnapping risk while carrying confidential prototypes and an unlocked smartphone. A later change introduces this additional requirement: A regional crisis interrupts ordinary cellular communications. Select THREE elements that together supply the initial control, objective evidence of effectiveness, and the changed-requirement response. (Select THREE.)
- Pretravel checks verify emergency contacts, minimal carried data and safe response channels.
- Activate preplanned alternate communications and duty-of-care escalation.
- Assume a standard office badge offers adequate protection during foreign travel.
- Coordinate safety-aware containment with clinical owners while preserving critical care continuity.
- Clinical and technical logs show spread stopped without unacceptable care interruption.
- Perform travel threat assessment and issue safety, emergency contact and device-hardening guidance.
Explanation
Correct Answers
A:Correct — observable control evidence. The relevant result is: Pretravel checks verify emergency contacts, minimal carried data and safe response channels. This provides a completed control test rather than an implementation promise.
B:Correct — changed condition. Emergency personnel support needs resilient channels beyond routine device security.
F:Correct — initial control. Personnel safety and sensitive asset handling require contextual planning before deployment.
Incorrect Answers
C:Incorrect — it fails the original constraint. Office access controls do not mitigate travel threats, physical coercion or device loss.
D:Incorrect — the measure Coordinate safety-aware containment with clinical owners while preserving critical care continuity. addresses a different case: A hospital has confirmed malware on clinical workstations but systems also support active patient care.
E:Incorrect — this evidence applies to another case: A hospital has confirmed malware on clinical workstations but systems also support active patient care. The specified requirement here is An executive travels to a region with elevated kidnapping risk while carrying confidential prototypes and an unlocked smartphone.
Question 811
A product team discovers access-control design problems only after code is released and security work has no place in feature planning. Which recommendation should the security leader make FIRST to address the stated objective?
- Defer all security review until the service has production customer traffic.
- Release evidence traces a threat scenario to a security requirement, design control and implemented test.
- Perform security-focused regression testing and controlled change approval before rollout.
- Introduce security requirements and threat modeling into design and backlog acceptance criteria.
Explanation
Correct Answer
D:Shift-left planning addresses trust boundaries before expensive implementation and release rework. The scenario is: A product team discovers access-control design problems only after code is released and security work has no place in feature planning.
Incorrect Answers
A:Late-only review increases remediation cost and exposure while missing architecture-level decisions. The rejected action is: Defer all security review until the service has production customer traffic.
B:This is useful evidence after implementation, rather than the FIRST recommended decision for this objective. Release evidence traces a threat scenario to a security requirement, design control and implemented test.
C:This addresses a distinct subsequent requirement: A later maintenance release changes authorization logic in an already deployed service. An implemented authorization change needs verification against existing security guarantees, not only initial design work.
Question 812
A product team discovers access-control design problems only after code is released and security work has no place in feature planning. A colleague instead proposes: "Defer all security review until the service has production customer traffic." Which finding BEST explains why the proposal should be rejected?
- Its only deficiency is a missing executive signature, even if the design still fails the stated requirement.
- It is inadequate only because of a different later condition: A later maintenance release changes authorization logic in an already deployed service.
- No evidence or governance records should be retained when evaluating this 8.1 decision.
- Late-only review increases remediation cost and exposure while missing architecture-level decisions.
Explanation
Correct Answer
D:Late-only review increases remediation cost and exposure while missing architecture-level decisions. This directly invalidates the proposed action: Defer all security review until the service has production customer traffic.
Incorrect Answers
A:Approval alone cannot fix the specific weakness: Late-only review increases remediation cost and exposure while missing architecture-level decisions.
B:The subsequent circumstance is separate and does not explain why this proposed action fails the initial case. An implemented authorization change needs verification against existing security guarantees, not only initial design work.
C:Destroying records would weaken oversight and cannot remedy the immediate technical or governance flaw: Late-only review increases remediation cost and exposure while missing architecture-level decisions.
Question 813
A product team discovers access-control design problems only after code is released and security work has no place in feature planning. After implementing "Introduce security requirements and threat modeling into design and backlog acceptance criteria.", what evidence BEST demonstrates that the intended security outcome is functioning?
- A note proposing to test this exact 8.1 measure in a future quarter.
- A declaration that no incident has been reported, without exercising the relevant control.
- A meeting record that the alternate design "Perform security-focused regression testing and controlled change approval before rollout." was discussed but never tested.
- Release evidence traces a threat scenario to a security requirement, design control and implemented test.
Explanation
Correct Answer
D:Release evidence traces a threat scenario to a security requirement, design control and implemented test. This verifies the original requirement because shift-left planning addresses trust boundaries before expensive implementation and release rework.
Incorrect Answers
A:An unexecuted future plan does not prove current effectiveness for the stated 8.1 objective. The evidence should include: Release evidence traces a threat scenario to a security requirement, design control and implemented test.
B:Absence of reported incidents is not a controlled validation of the requirement. A stronger proof is: Release evidence traces a threat scenario to a security requirement, design control and implemented test.
C:Discussion of a different design does not demonstrate the deployed control. An implemented authorization change needs verification against existing security guarantees, not only initial design work.
Question 814
The organization previously faced this problem: A product team discovers access-control design problems only after code is released and security work has no place in feature planning. Its requirement then changes: A later maintenance release changes authorization logic in an already deployed service. Which revised action BEST meets the new requirement?
- Introduce security requirements and threat modeling into design and backlog acceptance criteria.
- Defer all security review until the service has production customer traffic.
- Keep the original 8.1 policy unchanged, and defer the newly identified requirement without a risk decision.
- Perform security-focused regression testing and controlled change approval before rollout.
Explanation
Correct Answer
D:An implemented authorization change needs verification against existing security guarantees, not only initial design work. The appropriate revised action is: Perform security-focused regression testing and controlled change approval before rollout.
Incorrect Answers
A:This addresses the original situation: Shift-left planning addresses trust boundaries before expensive implementation and release rework. It does not directly meet the changed requirement: A later maintenance release changes authorization logic in an already deployed service.
B:The earlier rejected approach remains inappropriate. Late-only review increases remediation cost and exposure while missing architecture-level decisions.
C:The new requirement needs an accountable response, not automatic deferral. An implemented authorization change needs verification against existing security guarantees, not only initial design work.
Question 815
A product owner adds financial transaction features without security acceptance criteria or a threat model. What should the security manager recommend as the MOST appropriate response to the current requirement?
- Add age-related privacy and data protection requirements before extending the service.
- Include key revocation, endpoint closure and data disposition in the retirement phase of SDLC.
- Capture abuse cases, security requirements and testable acceptance criteria during initial design.
- Defer deciding any authorization requirements until customers report a breach.
Explanation
Correct Answer
C:Security decisions belong in SDLC planning before costly architecture is fixed. This directly addresses the stated situation.
Incorrect Answers
A:This is appropriate for a later condition (The product starts processing information from children.), but it does not directly resolve the initial need. New user population changes regulatory and ethical design obligations.
B:This response addresses a different condition: A product team retires an old mobile app but its API keys and customer data cache remain reachable for months. The present case requires the measure described by Capture abuse cases, security requirements and testable acceptance criteria during initial design.
D:Reactive-only design leaves predictable flaws and expensive rework. The proposal would not be defensible for this case.
Question 816
A product owner adds financial transaction features without security acceptance criteria or a threat model. A designer proposes: Defer deciding any authorization requirements until customers report a breach. What is the MOST significant security deficiency in this proposal?
- New user population changes regulatory and ethical design obligations.
- Threat models must evolve as trust paths and authentication behavior change.
- Reactive-only design leaves predictable flaws and expensive rework.
- Changed dependencies invalidate assumptions in the original assessment.
Explanation
Correct Answer
C:Reactive-only design leaves predictable flaws and expensive rework. This is the direct weakness in the proposed action.
Incorrect Answers
A:This explains a later shift in requirements (The product starts processing information from children.), not the failure of the current proposal.
B:This is an advantage of another design (Add risk-triggered threat modeling and security regression tests to the change workflow.), not the particular flaw of Defer deciding any authorization requirements until customers report a breach.
D:This is a limitation elsewhere: A development team ships weekly releases, but no process revisits threats when authentication flows change. It does not explain the deficiency of the specified proposed approach.
Question 817
A product owner adds financial transaction features without security acceptance criteria or a threat model. The organization has now implemented this response: Capture abuse cases, security requirements and testable acceptance criteria during initial design. Which observation would MOST directly demonstrate that the security objective was met?
- Every material identity change references updated threats and automated negative tests.
- An approved change ticket for Capture abuse cases, security requirements and testable acceptance criteria during initial design. without a completed verification result.
- Story acceptance records map threats to implemented access tests and design owners.
- Tracked improvements show higher control coverage and lower serious escaped flaws.
Explanation
Correct Answer
C:Story acceptance records map threats to implemented access tests and design owners. This validates that security decisions belong in SDLC planning before costly architecture is fixed.
Incorrect Answers
A:This other observation is relevant to: A development team ships weekly releases, but no process revisits threats when authentication flows change.
B:An approved change without an executed test cannot prove operating effectiveness. The needed evidence is Story acceptance records map threats to implemented access tests and design owners.
D:This demonstrates controls in another circumstance: A start-up wants a practical maturity plan for security engineering rather than immediate purchase of all tools.
Question 818
A previous security situation was: A product owner adds financial transaction features without security acceptance criteria or a threat model. Now the requirement changes: The product starts processing information from children. Which NEW action BEST answers the changed need?
- Defer deciding any authorization requirements until customers report a breach.
- Story acceptance records map threats to implemented access tests and design owners.
- Add age-related privacy and data protection requirements before extending the service.
- Capture abuse cases, security requirements and testable acceptance criteria during initial design.
Explanation
Correct Answer
C:New user population changes regulatory and ethical design obligations. The revised action is Add age-related privacy and data protection requirements before extending the service.
Incorrect Answers
A:This remains inappropriate: Reactive-only design leaves predictable flaws and expensive rework.
B:This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: Story acceptance records map threats to implemented access tests and design owners.
D:This is the appropriate response to the original situation: Security decisions belong in SDLC planning before costly architecture is fixed. It does not directly meet the new condition.
Question 819
A development team ships weekly releases, but no process revisits threats when authentication flows change. What should the security manager recommend as the MOST appropriate response to the current requirement?
- Capture abuse cases, security requirements and testable acceptance criteria during initial design.
- Add risk-triggered threat modeling and security regression tests to the change workflow.
- Treat the initial launch threat model as permanently correct regardless of later features.
- Evaluate federation trust and supplier assurance before migrating identities.
Explanation
Correct Answer
B:Threat models must evolve as trust paths and authentication behavior change. This directly addresses the stated situation.
Incorrect Answers
A:This response addresses a different condition: A product owner adds financial transaction features without security acceptance criteria or a threat model. The present case requires the measure described by Add risk-triggered threat modeling and security regression tests to the change workflow.
C:Changed dependencies invalidate assumptions in the original assessment. The proposal would not be defensible for this case.
D:This is appropriate for a later condition (The team adopts a third-party SSO platform to replace internal login.), but it does not directly resolve the initial need. An external identity dependency changes both attack surface and governance.
Question 820
A development team ships weekly releases, but no process revisits threats when authentication flows change. A designer proposes: Treat the initial launch threat model as permanently correct regardless of later features. What is the MOST significant security deficiency in this proposal?
- Maturity investment should target measurable secure development weaknesses.
- Changed dependencies invalidate assumptions in the original assessment.
- Tool inventory does not show whether engineers manage threats, defects and releases effectively.
- An external identity dependency changes both attack surface and governance.
Explanation
Correct Answer
B:Changed dependencies invalidate assumptions in the original assessment. This is the direct weakness in the proposed action.
Incorrect Answers
A:This is an advantage of another design (Assess current secure-development practices and prioritize improvements based on risk and capability gaps.), not the particular flaw of Treat the initial launch threat model as permanently correct regardless of later features.
C:This is a limitation elsewhere: A start-up wants a practical maturity plan for security engineering rather than immediate purchase of all tools. It does not explain the deficiency of the specified proposed approach.
D:This explains a later shift in requirements (The team adopts a third-party SSO platform to replace internal login.), not the failure of the current proposal.
