Secure SDLC

A Secure Software Development Lifecycle (SSDLC) integrates security practices at every stage of development.

Stages

1. Requirements - Define security requirements alongside functional requirements
2. Design - Perform threat modeling, use secure design patterns
3. Implementation - Follow secure coding guidelines, use secure libraries
4. Testing - Perform security testing (SAST, DAST, penetration testing)
5. Deployment - Harden configurations, implement monitoring
6. Maintenance - Apply patches, monitor for vulnerabilities
