Which option is not listed as something worked on in the artifacts described?

• A. Incident Response Plan
• B. System Security Plan
• C. Security Categorization
• D. POAM

Answer: (A)

In this context, the documents typically described as part of the system’s formal security artifacts are the System Security Plan, which lays out the system, its boundaries, and the security controls; Security Categorization, which assigns the impact levels for confidentiality, integrity, and availability; and the Plan of Actions and Milestones, which tracks remediation efforts for identified weaknesses. The Incident Response Plan, while very important for how an organization detects, responds to, and recovers from security incidents, isn’t one of these core artifacts listed in that set. It belongs to the broader incident response program and is addressed through incident response controls rather than as a primary RMF artifact described in this context. So the item not listed among the described artifacts is the Incident Response Plan.
