# Security Profile Example
2+
3+
Minimal configuration using the built-in `security` profile.
4+
5+
## Overview
6+
7+
This example demonstrates using the built-in `security` pipeline profile which includes:
8+
9+
- **analyze** (code2llm) - code analysis
10+
- **audit** (pip-audit) - dependency vulnerability scan
11+
- **bandit** - Python security issues
12+
- **secrets** (gitleaks) - API token and secret detection ← NEW!
13+
- **test** (pytest) - test execution
14+
15+
## Quick Start
16+
17+
```bash
18+
# Install security tools
19+
pip install bandit pip-audit
20+
# Install gitleaks: https://github.com/gitleaks/gitleaks/releases
21+
22+
# Run with security profile
23+
pyqual run
24+
```
25+
26+
## What This Demonstrates
27+
28+
The `profile: security` line activates the built-in security profile with all security stages pre-configured. This is the simplest way to enable secret detection in your pipeline.

### Secrets JSON Format
40+
41+
The secrets scanner outputs to `.pyqual/secrets.json`. Example format:
42+
43+
```json
44+
[
45+
{"severity": "critical", "description": "AWS Access Key"},
46+
{"severity": "high", "description": "GitHub Token"},
47+
{"severity": "medium", "description": "Generic API Key"}
48+
]
49+
```
50+
51+
Severity mapping:
52+
- `critical` = 4
53+
- `high` = 3
54+
- `medium` = 2
55+
- `low` = 1
56+
- unknown = 0
57+
58+
The `secrets_severity` metric returns the maximum severity level found.
