Which of the following is NOT a method for assessing security effectiveness?

In the context of evaluating security effectiveness, involving law enforcement in drills primarily focuses on external collaboration and emergency response preparedness rather than directly measuring or assessing the security measures and protocols in place. Effective security assessment methods are typically focused on analyzing data and feedback related to security incidents and performance within the organization's own scope.

Analyzing incident reports allows security teams to identify trends and areas that may need improvement based on real occurrences. Conducting staff satisfaction surveys can provide insights into how secure employees feel in their environment, which is essential for understanding the human factor in security. Comparing performance metrics helps organizations quantify their security effectiveness by measuring outcomes against predefined goals or objectives.

Engaging law enforcement can enhance operational readiness and response but does not serve as an intrinsic method for evaluating the effectiveness of the security protocols currently in place within the facility. Therefore, this choice stands out as not fitting with the core methods used for assessing security effectiveness.
