What is a breach of security?

A breach of security refers specifically to an incident where classified information is exposed without authorization. This exposure can occur through various means, such as a cyber incident, physical security lapse, or insider threat. The essence of a breach lies in the unauthorized access or disclosure of sensitive information, which poses potential risks to national security and the integrity of classified programs.

In comparing to other options, a routine inspection of security protocols, a report filed by security personnel, and a scheduled audit of security procedures are all proactive measures or actions taken to maintain or evaluate security rather than representing a failure in security. These activities are essential in identifying vulnerabilities and ensuring compliance with security regulations, but they do not constitute a breach themselves since they do not involve the unauthorized exposure of information. Understanding this distinction is crucial for anyone in a Facility Security Officer role, as it highlights the importance of recognizing and responding to actual security incidents effectively.
