Which role works with IS Reps and contractor personnel on all matters related to the authorization and maintenance of authorized contractor information systems?

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

Answer: (A)

Understanding who coordinates the authorization and ongoing maintenance of contractor information systems centers on the RMF-style security workflow. The Information System Security Professional/Security Control Assessor is the person who sits at the intersection of security requirements and the system’s operation, working with Information System Reps and contractor personnel to ensure the security controls are properly implemented, tested, and maintained. They lead or contribute to the security assessment activities, gather and review evidence, help prepare the authorization package, and oversee continuous monitoring so the system remains authorized (ATO) as changes occur. This role directly handles the ongoing assurance and documentation needed to keep contractor information systems operating within approved risk levels.

Other roles have different primary focus areas. A Counterintelligence Special Agent specializes in intelligence and investigative matters rather than the day-to-day authorization and assessment of system security. A Field Security Officer concentrates on physical and program security in field environments, not the ongoing authorization process for contractor IT systems. An Insider Threat Program Senior Official oversees insider threat programs and related policies, not the routine authorization and maintenance tasks tied to information system security controls.
