What is required to be issued in response to unauthorized access detected in a Physical Security Perimeter?

The requirement for issuing an alarm to designated personnel within a specified timeframe, such as 15 minutes, is a critical component of effective incident response protocols. In the context of Physical Security Perimeters, this rapid notification mechanism ensures that relevant security personnel are promptly aware of any unauthorized access events. This immediate communication allows for a swift response to investigate and mitigate potential security breaches, thereby safeguarding assets and ensuring the integrity of the facility.

The emphasis on a timeframe helps to establish both urgency and accountability in the response process, which is vital in maintaining a secure environment in accordance with the standards set forth in the NERC CIP guidelines. Timely alerts are crucial in preventing further unauthorized access or security complications.

Other options present different approaches to incident management, but the requirement for an alarm to designated personnel specifically addresses the immediate need for action and coordination in the event of unauthorized access, highlighting its importance within the broader framework of physical security protocols.
