API Key Protection
All API keys are stored securely and never exposed:
- Keys stored only in Kubernetes secrets
- Never logged or exposed in responses
- Automatic sanitization in all outputs
- Response validation before transmission
Least Privilege Access
All components follow least-privilege principles:
- Agent uses read-only Kubernetes API access
- Minimal RBAC permissions
- No write access to cluster resources
- Network policies restrict communication
Data Protection
Sensitive data is protected at rest and in transit:
- Encrypted database connections
- TLS for all API communications
- Secrets encrypted in Kubernetes
- Audit logging for all decisions
Threat Model
PatchPulse is designed to mitigate common threats:
- Unauthorized access: RBAC and network policies
- Data leakage: Comprehensive sanitization
- API abuse: Rate limiting and validation
- Supply chain: Signed container images
Security Best Practices
Recommendations for secure deployment:
- Use dedicated service accounts
- Enable Pod Security Standards
- Regular security updates
- Monitor audit logs
- Rotate API keys regularly
