The abbreviation FSO stands for which role?

• A. Federal Security Official
• B. Facility Security Officer
• C. Foreign Security Officer
• D. Facility System Operator

Answer: (B)

FSO refers to Facility Security Officer, the person responsible for managing and enforcing a site's security program. This role is the primary liaison with government security authorities and ensures compliance with security policies and safeguards when handling classified or sensitive information. Typical duties include establishing and maintaining the security plan, administering personnel security clearances, overseeing access control and escort procedures, ensuring proper storage and marking of classified materials, conducting security training, keeping records up to date, and coordinating incident reporting and corrective actions. In practice, the Facility Security Officer makes sure only appropriately cleared personnel access sensitive information, visitors are properly escorted, and safeguarding measures are current and effective. The other options don’t fit this context, as they don’t describe the standard site security lead for handling classified information.
