Which role is NOT described as providing counterintelligence best-practices guidance to IS Reps?

• A. Facility Security Officer (FSO)
• B. Counterintelligence Special Agent (CISA)
• C. Information System Security Professional/Security Control Assessor (ISSP/SCA)
• D. Insider Threat Program Senior Official (ITPSO)

Answer: (A)

Counterintelligence best-practices guidance to IS Reps comes from roles that manage intelligence threats, insider threats, and security controls within information systems. A Counterintelligence Special Agent is the dedicated expert for counterintelligence matters, providing guidance to identify and counter espionage and other intelligence threats. The Insider Threat Program Senior Official leads the insider threat program, shaping policies and guidance to reduce risks from individuals with access to sensitive information. The Information System Security Professional/Security Control Assessor role focuses on implementing and assessing security controls across systems, which includes embedding counterintelligence considerations into system security practices. The Facility Security Officer, while essential for physical security and facility clearance processes, does not typically provide counterintelligence best-practices guidance to IS Reps. Their focus is on physical access and facility-level security, not on guiding information system personnel in counterintelligence practices.
