Question 360
Security reports show that employees reuse a single short password across multiple corporate services. Which policy change reduces breach-reuse exposure?
Explanation
Correct Answer
Unique generated credentials limit cross-service compromise and reduce reliance on memorability. Recovery controls have to be tested against actual restore requirements and isolated from the same compromise path; possessing a backup is not evidence that a timely, usable restoration is possible. The stated evidence is security reports show that employees reuse a single short password across multiple corporate services. This distinction rules out “Force employees to share one password with their team”: shared secrets make both reuse and attribution problems worse. “Require long unique secrets and support approved password managers” addresses the specific security outcome rather than the separate function that alternative performs.
Incorrect Answers
Shared secrets make both reuse and attribution problems worse. Authentication checks a claimant, but it does not automatically narrow resource privileges or invalidate a different leaked secret. Here the decisive fact is security reports show that employees reuse a single short password across multiple corporate services. “Require long unique secrets and support approved password managers” matches that requirement because unique generated credentials limit cross-service compromise and reduce reliance on memorability.
Removing authentication is not an acceptable response to password reuse. The evidence is security reports show that employees reuse a single short password across multiple corporate services. Access entitlements govern which specific operations a principal may perform; granting broad roles can expand the damage of credential compromise. By contrast, “Require long unique secrets and support approved password managers” operates on the specific concern: unique generated credentials limit cross-service compromise and reduce reliance on memorability.
Shorter credentials increase guessing feasibility. Identity lifecycle includes proofing, authentication, authorization and deprovisioning; success in one phase never automatically establishes success in another. Here the decisive fact is security reports show that employees reuse a single short password across multiple corporate services. “Require long unique secrets and support approved password managers” matches that requirement because unique generated credentials limit cross-service compromise and reduce reliance on memorability.
