CA-3(6)_transfer-authorizations
DevOps & SecurityCA-3(6)_transfer-authorizations is an Agent Skill for devops & security published in the CyberStrikeus/CyberStrike repository on GitHub: a SKILL.md instruction file an AI agent can load to do this task.
Verify that individuals or systems transferring data between interconnecting systems have the requisite authorizations (i.e., write permissions or pri
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-3(6)_transfer-authorizations/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ca-3-6-transfer-authorizations, but wait for my approval before writing files or running scripts.
Copying this prompt does not install or run the skill. Review third-party files before use.
CA-3(6) Transfer Authorizations
Enhancement of: CA-3
High-Level Description
Family: Assessment, Authorization, and Monitoring (CA) Framework: NIST SP 800-53 Rev 5
To prevent unauthorized individuals and systems from making information transfers to protected systems, the protected system verifies—via independent means— whether the individual or system attempting to transfer information is authorized to do so. Verification of the authorization to transfer information also applies to control plane traffic (e.g., routing and DNS) and services (e.g., authenticated SMTP relays).
What to Check
- Verify CA-3(6) Transfer Authorizations is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for CA-3(6)
- Verify enhancement builds upon base control CA-3
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for CA-3(6) 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
Verify that individuals or systems transferring data between interconnecting systems have the requisite authorizations (i.e., write permissions or privileges) prior to accepting such data.
Implementation Guidance
To prevent unauthorized individuals and systems from making information transfers to protected systems, the protected system verifies—via independent means— whether the individual or system attempting to transfer information is authorized to do so. Verification of the authorization to transfer information also applies to control plane traffic (e.g., routing and DNS) and services (e.g., authenticated SMTP relays).
