Which of the following is a key element when determining security needs for an EAC system?

When determining security needs for an Electronic Access Control (EAC) system, a key element is the analysis of historical security incidents. Understanding past occurrences of security breaches, unauthorized access, or incidents within a facility provides essential insights into vulnerabilities and patterns that may need to be addressed. This historical context allows security planners to identify specific threats and assess the effectiveness of previous security measures, thereby enhancing the design and implementation of the EAC system to better protect against similar incidents in the future.

The focus on historical security incidents ensures that the EAC system is tailored to the actual risks faced by an organization, promoting a more effective and informed approach to security planning. By addressing the real threats evidenced by past incidents, security measures can be prioritized, ensuring resources are effectively allocated to protect against the most significant risks.
