What factor is considered when assessing the potential success of a security countermeasure?

Assessing the potential success of a security countermeasure involves evaluating its effectiveness. Effectiveness measures how well a specific countermeasure can mitigate identified risks, prevent security breaches, or respond to incidents. It encompasses the ability of the countermeasure to reduce vulnerabilities and threats to an acceptable level, thereby safeguarding sensitive information and assets.

While cost, desirability, and time are important considerations in the overall evaluation of a security program and its implementations, the core focus when determining the success of a specific countermeasure is its effectiveness in achieving its intended security objectives. This ensures that resources are focused on measures that not only align with strategic goals but also deliver tangible improvements in security posture.
