What must occur if unauthorized physical access is detected at a Physical Access Control System?

When unauthorized physical access is detected at a Physical Access Control System, it is essential to alert personnel within 15 minutes. This requirement is rooted in the need for a timely response to potential security breaches. Prompt notification allows security personnel to assess the situation, take necessary actions to mitigate risks, and ensure that any further unauthorized access can be prevented.

Timely alerts help in coordinating an effective response to incidents, which can include securing the area, investigating the breach, and possibly contacting law enforcement if needed. This proactive approach is crucial for maintaining the security and integrity of critical infrastructure.

While reporting the issue in 30 minutes and notifying all personnel immediately might seem like reasonable options, they do not align with the time-sensitive nature of addressing security threats effectively. Documenting the access attempt is important for record-keeping and future assessments but does not fulfill the immediate need for a response to unauthorized access.
