SC-5(3) Detection and Monitoring
Enhancement of: SC-5
High-Level Description
Family: System and Communications Protection (SC)
Framework: NIST SP 800-53 Rev 5
Organizations consider the utilization and capacity of system resources when managing risk associated with a denial of service due to malicious attacks. Denial-of-service attacks can originate from external or internal sources. System resources that are sensitive to denial of service include physical disk storage, memory, and CPU cycles. Techniques used to prevent denial-of-service attacks related to storage utilization and capacity include instituting disk quotas, configuring systems to automatically alert administrators when specific storage capacity thresholds are reached, using file compression technologies to maximize available storage space, and imposing separate partitions for system and user data.
What to Check
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for SC-5(3) 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.
