## 🔍 Scan Results Summary

### Secret Detection
- **Gitleaks:** $([ -f gitleaks-report.json ] && echo "✅ No secrets detected" || echo "❌ Check required")
- **detect-secrets:** $([ -f .secrets.baseline ] && echo "✅ Baseline validated" || echo "❌ Check required")

### Static Application Security Testing (SAST)
- **Semgrep:** $([ -f semgrep-report.json ] && jq -r '"Critical: " + ([.results[] | select(.extra.severity == "ERROR")] | length | tostring) + ", High: " + ([.results[] | select(.extra.severity == "WARNING")] | length | tostring)' semgrep-report.json || echo "❌ Report not found")

### Container Security
- **Trivy Vulnerabilities:** $([ -f trivy-report.json ] && jq -r '"Critical: " + ([.Results[]?.Vulnerabilities[]? | select(.Severity == "CRITICAL")] | length | tostring) + ", High: " + ([.Results[]?.Vulnerabilities[]? | select(.Severity == "HIGH")] | length | tostring) + ", Medium: " + ([.Results[]?.Vulnerabilities[]? | select(.Severity == "MEDIUM")] | length | tostring)' trivy-report.json || echo "❌ Report not found")

### Infrastructure as Code
- **Checkov:** $([ -f checkov-k8s-report.json ] && echo "✅ Kubernetes manifests scanned" || echo "❌ Report not found")
- **kube-score:** $([ -f kube-score-report.txt ] && echo "✅ Best practices validated" || echo "❌ Report not found")

## 🛡️ Security Gates Status

All security gates must pass for deployment to proceed:
- Critical vulnerabilities: ≤ ${SECURITY_GATE_CRITICAL} ✅
- High vulnerabilities: ≤ ${SECURITY_GATE_HIGH} ✅  
- Medium vulnerabilities: ≤ ${SECURITY_GATE_MEDIUM} ✅

## 📋 Recommendations

1. **Regular Updates:** Keep base images and dependencies updated
2. **Secret Management:** Use external secret managers (Vault, AWS Secrets Manager)
3. **Network Policies:** Implement Kubernetes network policies
4. **RBAC:** Apply least-privilege access controls
5. **Monitoring:** Enable runtime security monitoring
