How to use this skill
Bring this guide into your coding agent with a prompt tailored to the tool you use.
- Open your project in Codex.
- Copy and paste the prompt below.
- Review files and risks before approving any action.
Inspect the Agent Skill at https://github.com/CyberStrikeus/CyberStrike/blob/HEAD/.cyberstrike/skill/NIST/SP800-53_rev5/CA_assessment-authorization-and-monitoring/CA-7(3)_trend-analyses/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ca-7-3-trend-analyses, but wait for my approval before writing files or running scripts.

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.

Control Statement
Employ trend analyses to determine if control implementations, the frequency of continuous monitoring activities, and the types of activities used in the continuous monitoring process need to be modified based on empirical data.
Implementation Guidance
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.
