Question 630

A customer-facing API uses valid credentials but clients can modify numeric customer IDs to read other accounts. A later change introduces this additional requirement: The API adds privileged batch export for compliance officers. Select THREE elements that together supply the initial control, objective evidence of effectiveness, and the changed-requirement response. (Select THREE.)

  1. Perform authenticated object-level authorization tests across user and tenant roles.
  2. Cross-tenant object requests return denial with audit evidence and permitted reads succeed.
  3. Assess export authorization, logging and rate/volume limits separately.
  4. Check only for SQL injection and call access control testing complete.
  5. Use focused protocol configuration tests and negative handshakes with obsolete versions and ciphers.
  6. Deliberate deprecated protocol connections are rejected and supported suites negotiated.

Explanation

Correct Answers

A:

Correct — initial control. Broken object-level authorization can exist despite correctly working sign-in.

B:

Correct — observable control evidence. The relevant result is: Cross-tenant object requests return denial with audit evidence and permitted reads succeed. This provides a completed control test rather than an implementation promise.

C:

Correct — changed condition. A new high-volume operation introduces additional role and data-loss risks.

Incorrect Answers

D:

Incorrect — it fails the original constraint. Injection tests do not establish who may read a specific resource.

E:

Incorrect — the measure Use focused protocol configuration tests and negative handshakes with obsolete versions and ciphers. addresses a different case: A company replaces its legacy TLS library and wants to prove the new implementation resists protocol downgrade.

F:

Incorrect — this evidence applies to another case: A company replaces its legacy TLS library and wants to prove the new implementation resists protocol downgrade. The specified requirement here is A customer-facing API uses valid credentials but clients can modify numeric customer IDs to read other accounts.

Question 631

A security operations team wants to test whether its analysts detect a known adversary's lateral movement technique. What should the security manager recommend as the MOST appropriate response to the current requirement?

  1. Perform scoped authenticated vulnerability assessments with asset inventory and risk prioritization.
  2. Run an approved purple-team exercise with mapped attack emulation and detection engineering feedback.
  3. Interpret a quiet alert dashboard as proof that all lateral movement would be detected.
  4. Conduct a tightly scoped red-team exercise with deconfliction and stop conditions.

Explanation

Correct Answer

B:

Adversary emulation measures detection and response outcomes against plausible behaviors. This directly addresses the stated situation.

Incorrect Answers

A:

This response addresses a different condition: An enterprise has a large unpatched server inventory and needs non-disruptive identification of exposed weaknesses. The present case requires the measure described by Run an approved purple-team exercise with mapped attack emulation and detection engineering feedback.

C:

No alert without a test does not prove detection coverage. The proposal would not be defensible for this case.

D:

This is appropriate for a later condition (The team later wants a blind test of its real-world response readiness.), but it does not directly resolve the initial need. A blind exercise tests unprompted operational readiness rather than joint detector tuning.

Question 632

A security operations team wants to test whether its analysts detect a known adversary's lateral movement technique. A designer proposes: Interpret a quiet alert dashboard as proof that all lateral movement would be detected. What is the MOST significant security deficiency in this proposal?

  1. Premerge testing can catch code patterns and logic errors before deployment.
  2. No alert without a test does not prove detection coverage.
  3. Network scanning has limited visibility into application source and branches.
  4. A blind exercise tests unprompted operational readiness rather than joint detector tuning.

Explanation

Correct Answer

B:

No alert without a test does not prove detection coverage. This is the direct weakness in the proposed action.

Incorrect Answers

A:

This is an advantage of another design (Add static analysis, relevant security unit tests and peer review at controlled merge gates.), not the particular flaw of Interpret a quiet alert dashboard as proof that all lateral movement would be detected.

C:

This is a limitation elsewhere: A high-risk payment application has code-level authentication changes but no developer security tests before merge. It does not explain the deficiency of the specified proposed approach.

D:

This explains a later shift in requirements (The team later wants a blind test of its real-world response readiness.), not the failure of the current proposal.

Question 633

A security operations team wants to test whether its analysts detect a known adversary's lateral movement technique. The organization has now implemented this response: Run an approved purple-team exercise with mapped attack emulation and detection engineering feedback. Which observation would MOST directly demonstrate that the security objective was met?

  1. An approved change ticket for Run an approved purple-team exercise with mapped attack emulation and detection engineering feedback. without a completed verification result.
  2. Mapped simulated techniques produce expected telemetry and documented analyst actions.
  3. Deliberate deprecated protocol connections are rejected and supported suites negotiated.
  4. Controlled exercises show a statistically meaningful improvement in safe reporting.

Explanation

Correct Answer

B:

Mapped simulated techniques produce expected telemetry and documented analyst actions. This validates that adversary emulation measures detection and response outcomes against plausible behaviors.

Incorrect Answers

A:

An approved change without an executed test cannot prove operating effectiveness. The needed evidence is Mapped simulated techniques produce expected telemetry and documented analyst actions.

C:

This demonstrates controls in another circumstance: A company replaces its legacy TLS library and wants to prove the new implementation resists protocol downgrade.

D:

This other observation is relevant to: A security awareness program tracks course attendance but not user reporting behavior during phishing tests.

Question 634

A previous security situation was: A security operations team wants to test whether its analysts detect a known adversary's lateral movement technique. Now the requirement changes: The team later wants a blind test of its real-world response readiness. Which NEW action BEST answers the changed need?

  1. Mapped simulated techniques produce expected telemetry and documented analyst actions.
  2. Conduct a tightly scoped red-team exercise with deconfliction and stop conditions.
  3. Run an approved purple-team exercise with mapped attack emulation and detection engineering feedback.
  4. Interpret a quiet alert dashboard as proof that all lateral movement would be detected.

Explanation

Correct Answer

B:

A blind exercise tests unprompted operational readiness rather than joint detector tuning. The revised action is Conduct a tightly scoped red-team exercise with deconfliction and stop conditions.

Incorrect Answers

A:

This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: Mapped simulated techniques produce expected telemetry and documented analyst actions.

C:

This is the appropriate response to the original situation: Adversary emulation measures detection and response outcomes against plausible behaviors. It does not directly meet the new condition.

D:

This remains inappropriate: No alert without a test does not prove detection coverage.

Question 635

A development team must assess a compiled mobile app without access to all upstream source code. What should the security manager recommend as the MOST appropriate response to the current requirement?

  1. Use approved black-box dynamic testing plus available dependency and binary analysis.
  2. Declare source-only static analysis complete when no relevant source is available.
  3. Add code review and SAST to broaden test depth and confirm provenance.
  4. Add static analysis, relevant security unit tests and peer review at controlled merge gates.

Explanation

Correct Answer

A:

Testing strategy should match visibility into the application and release artifacts. This directly addresses the stated situation.

Incorrect Answers

B:

A test depending on absent source cannot evaluate the delivered executable. The proposal would not be defensible for this case.

C:

This is appropriate for a later condition (The vendor supplies authoritative source and build scripts after procurement.), but it does not directly resolve the initial need. Source availability expands possible assurance methods beyond binary-only evaluation.

D:

This response addresses a different condition: A high-risk payment application has code-level authentication changes but no developer security tests before merge. The present case requires the measure described by Use approved black-box dynamic testing plus available dependency and binary analysis.

Question 636

A development team must assess a compiled mobile app without access to all upstream source code. A designer proposes: Declare source-only static analysis complete when no relevant source is available. What is the MOST significant security deficiency in this proposal?

  1. A test depending on absent source cannot evaluate the delivered executable.
  2. Documentation is not proof of effective listener configuration.
  3. Source availability expands possible assurance methods beyond binary-only evaluation.
  4. Protocol security must be validated against actual negotiated behavior.

Explanation

Correct Answer

A:

A test depending on absent source cannot evaluate the delivered executable. This is the direct weakness in the proposed action.

Incorrect Answers

B:

This is a limitation elsewhere: A company replaces its legacy TLS library and wants to prove the new implementation resists protocol downgrade. It does not explain the deficiency of the specified proposed approach.

C:

This explains a later shift in requirements (The vendor supplies authoritative source and build scripts after procurement.), not the failure of the current proposal.

D:

This is an advantage of another design (Use focused protocol configuration tests and negative handshakes with obsolete versions and ciphers.), not the particular flaw of Declare source-only static analysis complete when no relevant source is available.

Question 637

A development team must assess a compiled mobile app without access to all upstream source code. The organization has now implemented this response: Use approved black-box dynamic testing plus available dependency and binary analysis. Which observation would MOST directly demonstrate that the security objective was met?

  1. Mobile tests capture input handling, storage and transport controls of the shipped app.
  2. Cross-tenant object requests return denial with audit evidence and permitted reads succeed.
  3. Sampled reviews identify removed excess rights with documented rationale and follow-up.
  4. An approved change ticket for Use approved black-box dynamic testing plus available dependency and binary analysis. without a completed verification result.

Explanation

Correct Answer

A:

Mobile tests capture input handling, storage and transport controls of the shipped app. This validates that testing strategy should match visibility into the application and release artifacts.

Incorrect Answers

B:

This demonstrates controls in another circumstance: A customer-facing API uses valid credentials but clients can modify numeric customer IDs to read other accounts.

C:

This other observation is relevant to: A privilege access-review process is required quarterly, but managers approve entire lists without examining entitlement changes.

D:

An approved change without an executed test cannot prove operating effectiveness. The needed evidence is Mobile tests capture input handling, storage and transport controls of the shipped app.

Question 638

A previous security situation was: A development team must assess a compiled mobile app without access to all upstream source code. Now the requirement changes: The vendor supplies authoritative source and build scripts after procurement. Which NEW action BEST answers the changed need?

  1. Add code review and SAST to broaden test depth and confirm provenance.
  2. Use approved black-box dynamic testing plus available dependency and binary analysis.
  3. Declare source-only static analysis complete when no relevant source is available.
  4. Mobile tests capture input handling, storage and transport controls of the shipped app.

Explanation

Correct Answer

A:

Source availability expands possible assurance methods beyond binary-only evaluation. The revised action is Add code review and SAST to broaden test depth and confirm provenance.

Incorrect Answers

B:

This is the appropriate response to the original situation: Testing strategy should match visibility into the application and release artifacts. It does not directly meet the new condition.

C:

This remains inappropriate: A test depending on absent source cannot evaluate the delivered executable.

D:

This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: Mobile tests capture input handling, storage and transport controls of the shipped app.

Question 639

A manufacturer uses industrial controllers whose processes cannot tolerate active port scans during production. What should the security manager recommend as the MOST appropriate response to the current requirement?

  1. Run aggressive authenticated scanning on live controllers at maximum concurrency.
  2. Conduct a controlled active test on the approved isolated maintenance window.
  3. Use focused protocol configuration tests and negative handshakes with obsolete versions and ciphers.
  4. Plan passive discovery and lab-based tests coordinated with plant safety owners.

Explanation

Correct Answer

D:

Safety-critical OT testing must avoid disruptive techniques that threaten physical operations. This directly addresses the stated situation.

Incorrect Answers

A:

Disruptive scanning may interrupt fragile controllers and create safety hazards. The proposal would not be defensible for this case.

B:

This is appropriate for a later condition (The plant schedules a verified maintenance outage for selected devices.), but it does not directly resolve the initial need. Maintenance conditions may permit stronger active validation with managed safety risk.

C:

This response addresses a different condition: A company replaces its legacy TLS library and wants to prove the new implementation resists protocol downgrade. The present case requires the measure described by Plan passive discovery and lab-based tests coordinated with plant safety owners.

Question 640

A manufacturer uses industrial controllers whose processes cannot tolerate active port scans during production. A designer proposes: Run aggressive authenticated scanning on live controllers at maximum concurrency. What is the MOST significant security deficiency in this proposal?

  1. Injection tests do not establish who may read a specific resource.
  2. Maintenance conditions may permit stronger active validation with managed safety risk.
  3. Broken object-level authorization can exist despite correctly working sign-in.
  4. Disruptive scanning may interrupt fragile controllers and create safety hazards.

Explanation

Correct Answer

D:

B:

This explains a later shift in requirements (The plant schedules a verified maintenance outage for selected devices.), not the failure of the current proposal.

C:

This is an advantage of another design (Perform authenticated object-level authorization tests across user and tenant roles.), not the particular flaw of Run aggressive authenticated scanning on live controllers at maximum concurrency.
