SA-4(8) Continuous Monitoring Plan for Controls
Enhancement of: SA-4
High-Level Description
Family: System and Services Acquisition (SA)
Framework: NIST SP 800-53 Rev 5
The objective of continuous monitoring plans is to determine if the planned, required, and deployed controls within the system, system component, or system service continue to be effective over time based on the inevitable changes that occur. Developer continuous monitoring plans include a sufficient level of detail such that the information can be incorporated into continuous monitoring programs implemented by organizations. Continuous monitoring plans can include the types of control assessment and monitoring activities planned, frequency of control monitoring, and actions to be taken when controls fail or become ineffective.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SA-4(8) implementation details. Verify the organization has documented how this control is satisfied.
Step 2: Validate Implementation
# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly
# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null
Step 3: Test Operating Effectiveness
Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.

Control Statement
Require the developer of the system, system component, or system service to produce a plan for continuous monitoring of control effectiveness that is consistent with the continuous monitoring program of the organization.
