Which of the following MOST effectively minimizes the impact of a control failure?

The most effective way tominimize the impact of a control failureis to employDefense in Depth, which involves:

Layered Security Controls:Implementing multiple, overlapping security measures to protect assets.

Redundancy:If one control fails (e.g., a firewall), others (like IDS, endpoint protection, and network monitoring) continue to provide protection.

Minimizing Single Points of Failure:By diversifying security measures, no single failure will compromise the entire system.

Adaptive Security Posture:Layered defenses allow quick adjustments and contain threats.

Other options analysis:

A. Business continuity plan (BCP):Focuses on maintaining operations after an incident, not directly on minimizing control failures.

B. Business impact analysis (BIA):Identifies potential impacts but does not reduce failure impact directly.

D. Information security policy:Guides security practices but does not provide practical mitigation during a failure.
