aws-sec-audit

aws-sec-audit is a command for coding agents from HermeticOrmus/LibreSecOps-Claude-Code. It costs 0 tokens per session (1,178 once invoked), scanned A, original, MIT.

A command for reviewing Amazon Web Services (AWS) security settings, including identity permissions, storage, networks, logging, and common misconfigurations. It accepts live read-only access, infrastructure code, or configuration exports.

In plain words
What is it for?
Use it to audit IAM, S3 buckets, VPC exposure, CloudTrail logging, Terraform, CloudFormation, CDK code, and selected security areas.
Why use it?
It provides a structured way to find insecure settings before deployment, during reviews, or after infrastructure changes.

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

aws-sec-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 4d 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.

/aws-sec-audit

Structured security audit of AWS configuration covering IAM, S3, VPC, CloudTrail, and common misconfigurations.

Trigger

Use when you need to:

  • Review AWS infrastructure configuration for security gaps
  • Audit Terraform, CloudFormation, or CDK templates before deployment
  • Prepare for a compliance audit or security review
  • Validate that security controls are properly configured after changes
  • Investigate whether an AWS environment follows security best practices

Input

One of:

  • Live environment: AWS CLI access with read-only permissions (SecurityAudit managed policy or equivalent)
  • Infrastructure-as-code: Terraform files (.tf), CloudFormation templates (.yaml/.json), CDK code
  • Configuration export: Output from aws iam get-account-authorization-details, Security Hub findings, Prowler reports
  • Specific scope: Focus area if not a full audit (e.g., "IAM only", "S3 buckets", "network exposure")

Process

Phase 1: Identity & Access Management

  1. Root account security

    • MFA enabled on root (aws iam get-account-summary -- check AccountMFAEnabled)
    • No root access keys (aws iam get-account-summary -- check AccountAccessKeysPresent)
    • Root usage in CloudTrail (should be near zero)
  2. IAM policies

    • Scan for "Effect": "Allow", "Action": "*", "Resource": "*" (full admin)
    • Check for inline policies vs managed policies (prefer managed)
    • Identify unused IAM roles and users (aws iam generate-credential-report)
    • Review cross-account trust relationships in role assume-role policies
    • Check for iam:PassRole with wildcard resource (privilege escalation vector)
  3. Access keys

    • Age of access keys (>90 days is a finding)
    • Users with multiple active access keys
    • Access keys on root account (should not exist)
  4. Password policy

    • Minimum length >= 14 characters
    • Complexity requirements enabled
    • Password reuse prevention (remember >= 24)

Phase 2: Storage Security

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
