Security by Design
The Secure Software Development Lifecycle embeds security requirements, threat modelling, and testing into every phase of software development — not as an afterthought.
SSDLC Phases
- Requirements: Define security user stories and acceptance criteria alongside functional requirements.
- Design: Conduct threat modelling sessions using STRIDE to identify architectural risks.
- Development: Apply secure coding standards (OWASP), code reviews, and SAST scanning.
- Testing: Run DAST, IAST, and penetration testing on staging environments.
- Deployment: Validate infrastructure configurations and secrets management.
- Maintenance: Monitor for new CVEs in dependencies and patch within SLA.
