Security is not a feature It’s a property like performance
and reliability
Security should be addressed at each step of the development
lifecycle
Design Implementation Vetification Release Security requirements Training Architecture reviews Threat
modelling Documentation Secure coding Code reviews Static analysis Dynamic analysis Pen testing Secure environnement Monitoring Incident Response Requirements & trainings
Requirements & trainings Use HSTS Must be HTTPS-only Have anti-CSRF
mechanism See Spring-Security ? Security checklists
Design Feedbacks-oriented meeting before any major changes enters development. Identifying
subjects that need closer follow-ups. Ensuring best practices. Architecture reviews
Impl. Static analysis Code analysis: Looks for common vulnerabilities pattern
in code. Composition analysis: Looks for vulnerable dependencies.
