CA-7(3) Trend Analyses

Enhancement of: CA-7

High-Level Description

Family: Assessment, Authorization, and Monitoring (CA) Framework: NIST SP 800-53 Rev 5

Trend analyses include examining recent threat information that addresses the types of threat events that have occurred in the organization or the Federal Government, success rates of certain types of attacks, emerging vulnerabilities in technologies, evolving social engineering techniques, the effectiveness of configuration settings, results from multiple control assessments, and findings from Inspectors General or auditors.

What to Check

Verify CA-7(3) Trend Analyses is documented in SSP
Confirm control is operating effectively
Review evidence of continuous monitoring for CA-7(3)
Verify enhancement builds upon base control CA-7

How to Test

Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for CA-7(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.
