## What it does

The skill audits cloud infrastructure across six categories: IAM, network, storage, compute, logging and secrets. Each one comes with ready CLI commands — `aws iam get-account-summary`, `gcloud projects get-iam-policy $PROJECT_ID`, `az role assignment list --all` — plus what to look for in the output: root without MFA, access keys older than 90 days, wildcard permissions, public buckets, rules allowing `0.0.0.0/0`, disabled VPC flow logs.

No CLI tools installed? The skill falls back to IaC files: Terraform, CloudFormation, Pulumi. It greps them for `"Action": "*"`, `"Resource": "*"`, hardcoded secrets and overly broad trust policies. Findings land in a markdown report: severity, resource, region, risk, evidence and the exact fix command. A prioritized action plan closes it out.

Boundaries are strict: only accounts and projects you already have access to. The skill refuses to exploit found misconfigurations on someone else's infrastructure. It also flags fixes that could hurt availability — tightening a security group can break connectivity between services. For role design and federation it points to `iam-audit`, for Kubernetes posture to `container-audit`, for secrets hygiene to `secrets-audit`.

## Requirements
- Works with: AWS, Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill cloud-audit -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/cloud-audit/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/cloud-audit/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill cloud-audit -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/cloud-audit/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill cloud-audit -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/cloud-audit/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install briiirussell/cybersecurity-skills cloud-audit
```

2. **Manually: put the files in place**
- File: `.github/skills/cloud-audit/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill cloud-audit -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/briiirussell/cybersecurity-skills --path skills/cloud-audit
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/cloud-audit/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add briiirussell/cybersecurity-skills --skill cloud-audit -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/briiirussell/cybersecurity-skills/tree/HEAD/skills/cloud-audit/SKILL.md

## When to use it
- find S3 buckets open to the public
- check for access keys older than 90 days
- strip wildcard permissions out of IAM policies
- scan Terraform for hardcoded secrets and broad trust policies
- produce a findings report with priorities and fix commands

## Example prompts
- audit my AWS account for public buckets and overprivileged roles
- review the Terraform in this repo for wildcard policies and hardcoded secrets
- check security groups for SSH and RDP open to the internet

# Cloud Audit — Cloud Infrastructure Security Review

Audit cloud infrastructure configurations for misconfigurations, excessive permissions, public exposure, and compliance gaps. Covers AWS, GCP, and Azure.

Cross-references: `iam-audit` for the consultant-style IAM deep-dive (design / audit / migrate across identity providers and federation patterns) — this skill includes an IAM section but stays at the cloud-posture level; for role design, JIT access, workload identity federation, and migration plans, invoke `iam-audit`. `container-audit` for Kubernetes-specific posture sitting on top of cloud. `secrets-audit` for secrets-manager hygiene and rotation.

Findings should use the three-disposition rule (Fixed / Deferred / Accepted Risk) per `owasp-audit`'s Report Format.

## Scope the Audit

Identify:
1. Cloud provider(s) and account(s)
2. Regions in use
3. Whether CLI tools are available (`aws`, `gcloud`, `az`) or reviewing IaC files (Terraform, CloudFormation, Pulumi)

## Audit Categories

### Identity and Access Management

**AWS:**
```bash
aws iam get-account-summary
aws iam list-users
aws iam generate-credential-report && aws iam get-credential-report --output text --query Content | base64 -d
```
Check for: root account usage without MFA, access keys older than 90 days, unused credentials, wildcard permissions (`"Action": "*"`), overprivileged roles.

**GCP:**
```bash
gcloud projects get-iam-policy $PROJECT_ID
gcloud iam service-accounts list
```
Check for: primitive roles (Owner/Editor) on too many principals, unused service accounts, service account keys instead of workload identity.

**Azure:**
```bash
az role assignment list --all
az ad user list
```
Check for: excessive Owner/Contributor assignments, guest users with high privileges.

**IaC review:** Grep Terraform/CloudFormation files for `"Action": "*"`, `"Resource": "*"`, hardcoded secrets, overly broad trust policies.

### Network Security
