# Security Audit

Scan, detect, and fix security issues in codebases and infrastructure. Covers dependency vulnerabilities, secret detection, OWASP top 10, SSL/TLS verification, file permissions, and secure coding patterns.

## When to Use

- Scanning project dependencies for known vulnerabilities
- Detecting hardcoded secrets, API keys, or credentials in source code
- Reviewing code for OWASP top 10 vulnerabilities (injection, XSS, CSRF, etc.)
- Verifying SSL/TLS configuration for endpoints
- Auditing file and directory permissions
- Checking authentication and authorization patterns
- Preparing for a security review or compliance audit

## Dependency Vulnerability Scanning

### Node.js

```bash
# Built-in npm audit
npm audit
npm audit --json | jq '.vulnerabilities | to_entries[] | {name: .key, severity: .value.severity, via: .value.via[0]}'

# Fix automatically where possible
npm audit fix

# Show only high and critical
npm audit --audit-level=high

# Check a specific package
npm audit --package-lock-only

# Alternative: use npx to scan without installing
npx audit-ci --high
```

### Python

```bash
# pip-audit (recommended)
pip install pip-audit
pip-audit
pip-audit -r requirements.txt
pip-audit --format=json

# safety (alternative)
pip install safety
safety check
safety check -r requirements.txt --json

# Check a specific package
pip-audit --requirement=- <<< "requests==2.25.0"
```

### Go

```bash
# Built-in vuln checker
go install golang.org/x/vuln/cmd/govulncheck@latest
govulncheck ./...

# Check specific binary
govulncheck -mode=binary ./myapp
```

### Rust

```bash
# cargo-audit
cargo install cargo-audit
cargo audit

# With fix suggestions
cargo audit fix
```

### Universal: Trivy (scans any project)

```bash
# Install: https://aquasecurity.github.io/trivy
# Scan filesystem
trivy fs .

# Scan specific language
trivy fs --scanners vuln --severity HIGH,CRITICAL .

# Scan Docker image
trivy image myapp:latest

# JSON output
trivy fs --format json -o results.jso...
