# Security Policy

## 🔒 Reporting a Vulnerability

**DO NOT** create public issues for security vulnerabilities.

### Reporting Process

1. **Email**: Send vulnerability details to: {security-email@example.com – *REMINDER: Provide security contact email*}
2. **PGP Encryption** (recommended): Use our PGP key: {PGP-KEY-ID}
   - Public key: `{repo-url}/-/blob/main/.well-known/security-pgp-key.asc`
3. **Alternative**: Use GitLab's confidential issues feature

### What to Include

- **Description**: Clear description of the vulnerability
- **Impact**: Who/what is affected
- **Reproduction**: Step-by-step instructions to reproduce
- **Environment**: Versions, OS, configuration
- **Proof of Concept**: Code snippet or exploit (if applicable)
- **Suggested Fix**: If you have one (optional)

### Response Timeline

| Timeline | Action |
|----------|--------|
| **24 hours** | Initial acknowledgement |
| **72 hours** | Preliminary assessment and severity rating |
| **7 days** | Detailed investigation and fix timeline |
| **30 days** | Patch released (target, may vary by severity) |
| **45 days** | Public disclosure (coordinated with reporter) |

## 🛡️ Supported Versions

**REMINDER: Update this table with actual supported versions.**

| Version | Supported          | End of Life |
|---------|--------------------|-------------|
| {latest-version} | ✅ Yes | TBD |
| {previous-version} | ✅ Yes | {EOL-date} |
| {older-version} | ❌ No | {EOL-date} |

## 🚨 Security Updates

### Severity Levels

We use the following severity levels:

- **🔴 Critical**: Immediate action required (remote code execution, data breach)
- **🟠 High**: Urgent fix needed (privilege escalation, authentication bypass)
- **🟡 Medium**: Important fix (information disclosure, denial of service)
- **🟢 Low**: Minor issue (configuration weakness, minor information leak)

### Notification Channels

Security updates are announced via:

1. **GitLab Security Advisories**: {repo-url}/-/security
2. **Mailing List**: {security-announce-list – *REMINDER: Create security mailing list*}
3. **RSS Feed**: {repo-url}/-/security.atom
4. **CHANGELOG.md**: All security fixes documented

## 🔐 Security Features

### Built-In Security

{project-name} implements security through:

- **Type safety**: {Language} provides compile-time guarantees
- **Memory safety**: {Rust/Ada SPARK verification – if applicable}
- **Formal verification**: {SPARK proofs for critical components – if applicable}
- **Sandboxing**: {Deno permissions model – if applicable}
- **Least privilege**: Minimal permissions by default

### Security Headers

**REMINDER: Document HTTP security headers if web application.**

If deployed as web service, the following headers are enforced:

```http
Content-Security-Policy: default-src 'self'; script-src 'none'
X-Frame-Options: DENY
X-Content-Type-Options: nosniff
Referrer-Policy: no-referrer
Permissions-Policy: geolocation=(), microphone=(), camera=()
Cross-Origin-Opener-Policy: same-origin
Cross-Origin-Embedder-Policy: require-corp
Cross-Origin-Resource-Policy: same-origin
Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
```

### Cryptographic Standards

**REMINDER: Document cryptographic algorithms used.**

- **Hashing**: SHAKE256(M, d) = KECCAK[512]
- **Signing**: Ed448 (post-quantum ready)
- **Encryption**: ChaCha20-Poly1305
- **Random**: OS-provided CSPRNG
- **No MD5/SHA1**: Deprecated algorithms forbidden

## 🔍 Security Audits

### Internal Audits

- **Pre-release**: Every release undergoes security review
- **Code review**: All merge requests reviewed for security issues
- **Automated scanning**: CI/CD includes security scans

```bash
# Run security audit locally
just audit-security

# Check for known vulnerabilities
just deps-audit

# SPDX compliance
just audit-licence
```

### External Audits

**REMINDER: Document external security audits if applicable.**

| Date | Auditor | Scope | Report |
|------|---------|-------|--------|
| {date} | {auditor} | {scope} | [Link to report] |

## 🛡️ Secure Development

### Pre-Commit Checks

Security checks enforced via Robot Vacuum Cleaner (RVC):

- **SPDX headers**: All files attributed
- **Secret scanning**: No API keys, tokens, passwords
- **Dependency audit**: No known vulnerabilities
- **Licence compliance**: All dependencies compatible

### Security Training

**REMINDER: Link to security training resources for contributors.**

Contributors are expected to follow secure coding practices:

- [OWASP Top 10](https://owasp.org/www-project-top-ten/)
- [CWE Top 25](https://cwe.mitre.org/top25/)
- Language-specific security guides:
