access-control-identity-audit

access-control-identity-audit is a skill for Claude Code, Codex from vaquarkhan/compliance-agent-skills. It costs 114 tokens per session (1,722 once invoked), scanned A, original, MIT.

An identity and access audit skill for checking who can access systems and what they are allowed to do. It covers human users and non-human identities such as agent service accounts and API keys, against SOC 2, HIPAA, and PCI requirements.

In plain words
What is it for?
Use it to review cloud permissions, agent and MCP tool access, privileged accounts, multi-factor authentication coverage, and joiner-mover-leaver processes.
Why use it?
It helps find excessive permissions, missing multi-factor authentication, weak credential controls, and incomplete access removal. These problems can expose sensitive systems or data and create compliance gaps.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

access-control-identity-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Access Control Identity Audit

Overview

This skill performs identity and access management (IAM) audits mapped to:

  • SOC 2 CC6.1–CC6.8: logical access, credential management, access removal
  • HIPAA §164.312(a)(1): access control implementation specifications
  • PCI-DSS Req 7: restrict access to CHD by business need-to-know
  • PCI-DSS Req 8: identify and authenticate users

AI agent deployments introduce non-human identities: MCP service accounts, LLM API keys, agent runtime roles, and deanonymization tools. These require the same rigor as human admin accounts.

When to Use

Use this skill when:

  • Quarterly access reviews or SOC 2 CC6.2/CC6.3 evidence collection
  • Auditing cloud IAM (AWS IAM, Azure RBAC, GCP IAM) for least privilege
  • Reviewing MCP OAuth scopes and agent tool permissions
  • Joiner-mover-leaver (JML) process validation
  • MFA coverage assessment for privileged and ePHI/CDE access
  • Investigating ** excessive permissions** on service accounts running agents

Do not use this skill when:

  • Network segmentation and firewall rules (use pci-dss-network-segmentation)
  • BAA legal review (use hipaa-baa-vendor-assessment)
  • Log integrity architecture (use audit-logging-integrity)

Core Process

Execute steps in order.

Step 1: Identity inventory

  1. Export all identities from authoritative IdP and cloud IAM:
    • Human users, groups, roles
    • Service accounts, API keys, OAuth clients (MCP, agent, CI/CD)
  2. Classify each identity:
    • Human standard, Human privileged, Non-human service, Emergency break-glass
  3. Tag data access scope: ePHI, CHD, Confidential, Public
  4. Artifact: identity-inventory-{id}.csv.

Step 2: SOC 2 CC6 mapping

Criterion Audit action
CC6.1 Logical access security software/infrastructure
CC6.2 User registration and authorization before issuance
CC6.3 User modification and removal on role change
CC6.4 Access restrictions to confidential information
CC6.5 Protection against unauthorized access during transmission/session
CC6.6 System boundaries and segmentation (cross-ref network skill)
CC6.7 Transmission, movement, removal restrictions
CC6.8 Prevention of unauthorized software
