## Security Pipeline Patterns

### Pre-Commit Security
```yaml
# .pre-commit-config.yaml
repos:
  - repo: https://github.com/zricethezav/gitleaks
    hooks:
      - id: gitleaks

  - repo: https://github.com/Yelp/detect-secrets
    hooks:
      - id: detect-secrets

  - repo: https://github.com/semgrep/semgrep
    hooks:
      - id: semgrep
        args: ['--config', 'auto']
```

### CI Security Stage
```yaml
# GitHub Actions security job
security:
  runs-on: ubuntu-latest
  steps:
    - name: SAST Scan
      uses: semgrep/semgrep-action@v1

    - name: Dependency Scan
      uses: snyk/actions/node@master

    - name: Container Scan
      uses: aquasecurity/trivy-action@master
      with:
        image-ref: ${{ env.IMAGE }}

    - name: IaC Scan
      uses: bridgecrewio/checkov-action@master
```

### Secret Management Pattern
```yaml
# Vault integration pattern
apiVersion: secrets-store.csi.x-k8s.io/v1
kind: SecretProviderClass
metadata:
  name: vault-secrets
spec:
  provider: vault
  parameters:
    vaultAddress: "https://vault.example.com"
    roleName: "app-role"
    objects: |
      - objectName: "db-password"
        secretPath: "secret/data/app/db"
        secretKey: "password"
```

## Security Policies

### Container Policy
```rego
# OPA policy for container security
package container.security

deny[msg] {
    input.container.securityContext.privileged == true
    msg = "Privileged containers are not allowed"
}

deny[msg] {
    not input.container.securityContext.runAsNonRoot == true
    msg = "Containers must run as non-root"
}

deny[msg] {
    not input.container.resources.limits.memory
    msg = "Memory limits must be set"
}
```

### Network Policy
```yaml
# Kubernetes NetworkPolicy
apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: default-deny-all
spec:
  podSelector: {}
  policyTypes:
    - Ingress
    - Egress
```

## Output Artifacts

### Security Assessment Report
```markdown
# Security Assessment: [Project]

## Executive Summary
- **Risk Level**: [High/Medium/Low]
- **Critical Findings**: [Count]
- **High Findings**: [Count]

## Findings

### Critical
| ID | Title | Location | Remediation |
|----|-------|----------|-------------|
| ... | ... | ... | ... |

### High
| ID | Title | Location | Remediation |
|----|-------|----------|-------------|
| ... | ... | ... | ... |

## Recommendations
1. [Priority recommendation]
2. [Second recommendation]

## Compliance Status
| Control | Status |
|---------|--------|
| ... | ... |
```

### SBOM Document
```json
{
  "bomFormat": "CycloneDX",
  "specVersion": "1.4",
  "components": [
    {
      "type": "library",
      "name": "express",
      "version": "4.18.2",
      "purl": "pkg:npm/express@4.18.2"
    }
  ]
}
```

## Best Practices

### Secure Development
1. **Threat Modeling**: Before implementation
2. **Security Requirements**: Part of user stories
3. **Secure Coding Training**: Regular education
4. **Code Review**: Security-focused reviews
5. **Security Champions**: Per-team advocates

### Pipeline Security
1. **Least Privilege**: Minimal permissions
2. **Signed Artifacts**: Verify integrity
3. **Immutable Infrastructure**: No runtime changes
4. **Audit Logging**: All actions logged
5. **Break Glass**: Emergency access procedures

### Runtime Security
1. **Defense in Depth**: Multiple layers
2. **Zero Trust**: Verify everything
3. **Monitoring**: Security event detection
4. **Incident Response**: Automated playbooks
5. **Regular Patching**: Automated updates

## Collaboration

Works closely with:
- **security-auditor**: For security assessments
- **cicd-manager**: For pipeline integration
- **architect**: For security architecture
