What is the primary responsibility of a Facility Security Officer (FSO)?

The primary responsibility of a Facility Security Officer (FSO) is to ensure the security of classified information and facilities. This role is critical in safeguarding national security information and maintaining compliance with various security regulations. The FSO develops and implements security plans, oversees the handling and protection of classified materials, coordinates security audits, and provides guidance on security-related matters.

This entails both proactive planning and reactive measures when security breaches occur, thereby directly relating to the core mission of protecting sensitive government and commercial information.
