# Security Policy

## Supported Versions

We release patches for security vulnerabilities for the following versions:

| Version | Supported          |

| < 1.0   | :x:                |

## Reporting a Vulnerability

We take the security of Enterprise Service seriously. If you believe you have found a security vulnerability, please report it to us as described below.

### Reporting Process

**Please do not report security vulnerabilities through public GitHub issues.**

Instead, please report them via email to:
- **Email**: security@rhodium-example.com
- **Subject**: [SECURITY] Brief description of vulnerability

You should receive a response within 48 hours. If for some reason you do not, please follow up via email to ensure we received your original message.

### What to Include

Please include the following information:
- Type of issue (e.g., buffer overflow, SQL injection, cross-site scripting)
- Full paths of source file(s) related to the manifestation of the issue
- The location of the affected source code (tag/branch/commit or direct URL)
- Any special configuration required to reproduce the issue
- Step-by-step instructions to reproduce the issue
- Proof-of-concept or exploit code (if possible)
- Impact of the issue, including how an attacker might exploit it

### Our Response

We will:
1. Confirm receipt of your vulnerability report
2. Assess the issue and determine its impact
3. Develop a fix and security advisory
4. Release a patched version
5. Publicly disclose the vulnerability after the patch is released

## Security Best Practices

### For Users

#### Deployment Security

1. **Use HTTPS**: Always deploy behind a TLS terminator
2. **Environment Variables**: Never commit secrets to version control
3. **Updates**: Keep dependencies up to date
4. **Monitoring**: Enable security monitoring and logging
5. **Network Security**: Use firewall rules to restrict access

#### Configuration Security

```bash
# Good: Use environment variables
export DATABASE_URL="postgresql://..."

# Bad: Hard-coded credentials
# NEVER do this!
```

#### Container Security

```dockerfile
# Use specific versions, not :latest
FROM rust:1.70-slim

# Run as non-root user
RUN useradd -m -u 1000 appuser
USER appuser

# Only copy necessary files
COPY --chown=appuser:appuser target/release/enterprise-service /app/
```

### For Contributors

#### Code Security

1. **Input Validation**: Always validate and sanitize user inputs
2. **Error Handling**: Never expose sensitive information in errors
3. **Dependencies**: Review dependencies before adding
4. **Secrets**: Use environment variables, never hard-code
5. **Least Privilege**: Grant minimum necessary permissions

#### Secure Coding Practices

```rust
// Good: Input validation
if payload.name.is_empty() {
    return Err(AppError::InvalidInput("Name cannot be empty".to_string()));
}

// Good: Safe error messages
#[error("User not found")]
UserNotFound, // Don't expose internal details

// Bad: Exposing internal details
#[error("Database error: {0}")]
DatabaseError(String), // May leak connection strings, etc.
```

## Security Features

### Current Implementations

#### Input Validation

- Email format validation
- Required field checking
- Length limits on inputs
- Type safety via Rust's type system

#### Error Handling

- Structured error types
- Safe error messages (no information leakage)
- Proper HTTP status codes
- Logging of security events

#### Dependency Management

- Regular dependency audits via `cargo audit`
- Automated security scanning in CI/CD
- Minimal dependency footprint
- Pinned dependencies via Cargo.lock

#### Build Security

- Reproducible builds
- SBOM (Software Bill of Materials) generation
- Build provenance tracking
- Signature verification (planned)

### Security Headers

When deployed, ensure these HTTP headers are set:

```
X-Content-Type-Options: nosniff
X-Frame-Options: DENY
X-XSS-Protection: 1; mode=block
Strict-Transport-Security: max-age=31536000; includeSubDomains
Content-Security-Policy: default-src 'self'
```

## Vulnerability Scanning

### Automated Scans

We use the following tools in our CI/CD pipeline:

1. **cargo-audit**: Scans dependencies for known vulnerabilities
2. **Dependabot**: Automated dependency updates
3. **GitHub Security**: Code scanning and secret detection
4. **Trivy**: Container image scanning (when applicable)

### Manual Security Reviews

- Security review required for all PRs touching:
  - Authentication/authorization
  - Input validation
  - Cryptographic operations
  - Network communication
- Quarterly security audits of entire codebase
- Annual penetration testing (for production deployments)

## Known Security Considerations

### Current Limitations

1. **In-Memory Storage**: Current implementation uses in-memory storage
   - **Risk**: Data loss on restart
   - **Mitigation**: Production should use persistent database
   - **Status**: Documented in ARCHITECTURE.md

2. **No Authentication**: Current version has no authentication
   - **Risk**: Unrestricted access to API
   - **Mitigation**: Deploy behind auth gateway or implement JWT
   - **Status**: Planned for v2.0

3. **Rate Limiting**: Not currently implemented
   - **Risk**: Denial of service attacks
   - **Mitigation**: Use reverse proxy with rate limiting
   - **Status**: Planned enhancement

### Future Security Enhancements

See [docs/adr/003-security-roadmap.md](docs/adr/003-security-roadmap.md)

- [ ] JWT authentication
- [ ] Role-based access control (RBAC)
- [ ] API rate limiting
- [ ] Request signature verification
- [ ] Audit logging
- [ ] Encryption at rest
- [ ] mTLS support

## Security Testing

### Security Test Suite

```bash
# Run security audit
cargo audit

# Check for vulnerabilities in dependencies
cargo outdated

# Run tests with security-focused scenarios
cargo test security::

# Fuzz testing (when implemented)
cargo fuzz run
```

### Penetration Testing

For production deployments:
- Annual penetration testing recommended
- Bug bounty program encouraged
- Security audit before major releases

## Compliance

### Standards Adherence

- **OWASP Top 10**: Mitigations implemented
- **CWE/SANS Top 25**: Risk assessment completed
- **NIST Cybersecurity Framework**: Aligned practices

### Regulatory Compliance

For specific compliance requirements (GDPR, HIPAA, SOC 2), additional controls may be needed. Please contact us for compliance-specific guidance.
