Pass ISC CISSP Exam in First Attempt Guaranteed!

This other observation is relevant to: A legacy cryptographic service uses low-entropy human passwords directly as encryption keys.

An approved change without an executed test cannot prove operating effectiveness. The needed evidence is A controlled adversary-in-the-middle proxy cannot authenticate with a captured transient code.

This demonstrates controls in another circumstance: A web service compares secret authentication tags with variable-time string operations and leaks timing differences.

This remains inappropriate: Extended OTP validity can make relay easier and does not bind to the origin.

This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: A controlled adversary-in-the-middle proxy cannot authenticate with a captured transient code.

This is the appropriate response to the original situation: Credential relay can defeat phishable OTP factors without stealing long-term secrets. It does not directly meet the new condition.

This response addresses a different condition: An attacker intercepts an enterprise login flow and relays a real user's one-time password into the legitimate site. The present case requires the measure described by Use memory-hard password-based key derivation with strong random salts and enforce acceptable secret strength.

Encoding supplies no resistance to brute-force guesses or key recovery. The proposal would not be defensible for this case.

This is appropriate for a later condition (A database leak includes stored verifier hashes and unsalted legacy password entries.), but it does not directly resolve the initial need. Compromised verifier storage introduces a password database protection and recovery problem.

This is an advantage of another design (Use constant-time verification and limit requests across the relevant secret boundary.), not the particular flaw of Apply a reversible encoding operation and call it password protection.

This is a limitation elsewhere: A web service compares secret authentication tags with variable-time string operations and leaks timing differences. It does not explain the deficiency of the specified proposed approach.

This explains a later shift in requirements (A database leak includes stored verifier hashes and unsalted legacy password entries.), not the failure of the current proposal.

This is appropriate for a later condition (The agency must locate a secure evidence room inside the selected building.), but it does not directly resolve the initial need. An internal room requires defense in depth and custody controls beyond regional site selection.

This response addresses a different condition: A critical server room shares one power feed and experiences brief outages whenever building maintenance occurs. The present case requires the measure described by Evaluate environmental hazards, critical service proximity and physical risk before selecting the facility.

Low cost does not offset severe flooding, contamination or evacuation exposure. The proposal would not be defensible for this case.

This explains a later shift in requirements (The agency must locate a secure evidence room inside the selected building.), not the failure of the current proposal.

This is an advantage of another design (Select suitable detection and suppression under life-safety rules and asset-specific environmental risk assessment.), not the particular flaw of Select the site solely because its rental cost is the lowest available.

This is a limitation elsewhere: An archival media room uses a water sprinkler system without assessing damage to irreplaceable evidence assets. It does not explain the deficiency of the specified proposed approach.

This other observation is relevant to: An architect chooses security controls from a catalog but cannot show which sensitive-data requirements each control addresses.

An approved change without an executed test cannot prove operating effectiveness. The needed evidence is Site-assessment records document hazard maps, utility routes, access zones and approved tradeoffs.

This demonstrates controls in another circumstance: A new high-risk payment system enters design without a written data classification or abuse case model.

This remains inappropriate: Low cost does not offset severe flooding, contamination or evacuation exposure.

This is a record of how the initial safeguard would be checked, not an action implementing the newly requested condition: Site-assessment records document hazard maps, utility routes, access zones and approved tradeoffs.

This is the appropriate response to the original situation: Facility security begins with site characteristics that cannot be easily repaired with access controls. It does not directly meet the new condition.

This response addresses a different condition: An archival media room uses a water sprinkler system without assessing damage to irreplaceable evidence assets. The present case requires the measure described by Provide appropriately engineered redundant power, UPS capacity and tested failover procedures.

Access barriers do not restore lost electrical power. The proposal would not be defensible for this case.

This is appropriate for a later condition (Business impact analysis now requires extended operations during utility failure.), but it does not directly resolve the initial need. Short-ride UPS support is insufficient for sustained utility outages.

This is an advantage of another design (Select suitable detection and suppression under life-safety rules and asset-specific environmental risk assessment.), not the particular flaw of Install additional locks on the server-room door as the primary continuity measure.

This is a limitation elsewhere: An archival media room uses a water sprinkler system without assessing damage to irreplaceable evidence assets. It does not explain the deficiency of the specified proposed approach. In the current case, the assessed requirement is: A critical server room shares one power feed and experiences brief outages whenever building maintenance occurs. A designer proposes: Install additional locks on the server-room door as the primary continuity measure. What is the MOST significant security deficiency in this proposal.

This explains a later shift in requirements (Business impact analysis now requires extended operations during utility failure.), not the failure of the current proposal.

An approved change without an executed test cannot prove operating effectiveness. The needed evidence is A controlled feed failure keeps approved loads running through the targeted window.

This demonstrates controls in another circumstance: An archival media room uses a water sprinkler system without assessing damage to irreplaceable evidence assets.

This other observation is relevant to: An internet-facing service exposes optional debug and administrative endpoints in production by default. In the current case, the assessed requirement is: A critical server room shares one power feed and experiences brief outages whenever building maintenance occurs. The organization has now implemented this response: Provide appropriately engineered redundant power, UPS capacity and tested failover procedures. Which observation would MOST directly demonstrate that the security objective was met.
