Pass ISC CISSP Exam in First Attempt Guaranteed!

Possession of the signing key lets an attacker generate apparently valid malicious artifacts. The proposal would not be defensible for this case.

This is appropriate for a later condition (An incident confirms unauthorized use of the signing identity.), but it does not directly resolve the initial need. Known key compromise requires trust invalidation, not only better future storage.

This response addresses a different condition: A container registry allows deployments from arbitrary unsigned images supplied by any engineer. The present case requires the measure described by Move signing operations into protected key storage with restricted release identity and auditable use.

This is a limitation elsewhere: Developers bypass security tests by merging directly to the main repository branch during release pressure. It does not explain the deficiency of the specified proposed approach.

This explains a later shift in requirements (An incident confirms unauthorized use of the signing identity.), not the failure of the current proposal.

This is an advantage of another design (Enforce protected branches with required reviews, test outcomes and bounded emergency overrides.), not the particular flaw of Leave the key in the logs and rely on signed files as proof of safe release.

This demonstrates controls in another circumstance: A project fetches external CI actions by mutable branch name and gives each build job a production administration token.

This other observation is relevant to: A legacy application has no inventory of dependencies or artifact versions used in releases.

An approved change without an executed test cannot prove operating effectiveness. The needed evidence is A signing test enforces protected identity and key access without exposing raw private material.

This is the appropriate response to the original situation: Artifact signatures are untrustworthy if attackers can steal the signing key. It does not directly meet the new condition.

This remains inappropriate: Possession of the signing key lets an attacker generate apparently valid malicious artifacts.

This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: A signing test enforces protected identity and key access without exposing raw private material.

This is appropriate for a later condition (A zero-day impacts the base image of several already running services.), but it does not directly resolve the initial need. Runtime exposure persists after the original admission decision.

This response addresses a different condition: Developers bypass security tests by merging directly to the main repository branch during release pressure. The present case requires the measure described by Require approved image provenance, scanning policy and deploy-time signature validation.

Names are mutable labels, not cryptographic evidence of approved content. The proposal would not be defensible for this case.

This concerns a later and different need: A zero-day impacts the base image of several already running services. Runtime exposure persists after the original admission decision.

The proposed control fits another scenario: A project fetches external CI actions by mutable branch name and gives each build job a production administration token. It does not directly address this scenario's primary requirement.

Names are mutable labels, not cryptographic evidence of approved content.

This other observation is relevant to: A build system signs release artifacts using a private key exposed in logs visible to all developers.

An approved change without an executed test cannot prove operating effectiveness. The needed evidence is Unsigned or untrusted images fail deployment while reviewed digests succeed.

This demonstrates controls in another circumstance: A team receives repeated reports of accidentally committed API keys but only removes the affected lines.

This remains inappropriate: Names are mutable labels, not cryptographic evidence of approved content.

This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: Unsigned or untrusted images fail deployment while reviewed digests succeed.

This is the appropriate response to the original situation: Supply-chain policy must enforce trusted source and acceptable risk at deployment. It does not directly meet the new condition.

This response addresses a different condition: A project fetches external CI actions by mutable branch name and gives each build job a production administration token. The present case requires the measure described by Enforce protected branches with required reviews, test outcomes and bounded emergency overrides.

Intentions do not enforce security requirements or prevent unsafe immediate releases. The proposal would not be defensible for this case.

This is appropriate for a later condition (A critical security fix must ship before the normal code review meeting.), but it does not directly resolve the initial need. Emergency procedures can preserve accountability without removing all change gates.

Changing detector sensitivity can mask real vulnerabilities. The proposal would not be defensible for this case.

This is appropriate for a later condition (A new release adds an unfamiliar programming language with weak scanner support.), but it does not directly resolve the initial need. Assessment capability must follow changes in implementation technology.

This response addresses a different condition: A mobile application passes security unit tests but a live update introduces unsafe data caching on shared devices. The present case requires the measure described by Measure meaningful defect discovery, coverage, escaped vulnerabilities and rule configuration changes.

This is a limitation elsewhere: A vendor claims zero vulnerabilities in software, but the client needs credible evidence for purchasing decisions. It does not explain the deficiency of the specified proposed approach.

This explains a later shift in requirements (A new release adds an unfamiliar programming language with weak scanner support.), not the failure of the current proposal.

This is an advantage of another design (Request scoped assessment methods, limits, independent evidence and remediation history.), not the particular flaw of Treat any reduction in scan alerts as definitive evidence of safer software.
