DevOps & SecurityAC-17(2)_protection-of-confidentiality-and-integrity-using-encryption 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.
Implement cryptographic mechanisms to protect the confidentiality and integrity of remote access sessions.
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/AC_access-control/AC-17(2)_protection-of-confidentiality-and-integrity-using-encryption/SKILL.md and all supporting files. Report provenance, permissions, scripts, dependencies, and security risks. Propose an exact installation into .agents/skills/ac-17-2-protection-of-confidentiality-and-integrity-using-encryption, but wait for my approval before writing files or running scripts.

AC-17(2) Protection of Confidentiality and Integrity Using Encryption
Enhancement of: AC-17
High-Level Description
Family: Access Control (AC) Framework: NIST SP 800-53 Rev 5
Virtual private networks can be used to protect the confidentiality and integrity of remote access sessions. Transport Layer Security (TLS) is an example of a cryptographic protocol that provides end-to-end communications security over networks and is used for Internet communications and online transactions.
What to Check
- Verify AC-17(2) Protection of Confidentiality and Integrity Using Encryption is documented in SSP
- Confirm control is operating effectively
- Review evidence of continuous monitoring for AC-17(2)
- Verify enhancement builds upon base control AC-17
How to Test
Step 1: Review Documentation
Examine the System Security Plan (SSP) and related artifacts for AC-17(2) 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.
