Integrating security into the Software Development Lifecycle (SDLC), often referred to as DevSecOps or Secure SDLC, is paramount for building resilient and secure applications. It's about shifting security left – making it an integral part of the development process from the very beginning, rather than an afterthought.

Key Stages for Security Integration

• Requirements & Design: Conduct threat modeling and define security requirements.
• Development: Use secure coding practices, perform static application security testing (SAST).
• Testing: Implement dynamic application security testing (DAST), penetration testing, and vulnerability assessments.
• Deployment: Secure configurations, manage secrets effectively.
• Maintenance: Continuous monitoring, patch management, and incident response planning.

By fostering a culture of security awareness and providing developers with the right tools and training, organizations can significantly reduce vulnerabilities and the cost of remediation. A Secure SDLC not only enhances security but also improves software quality and accelerates delivery.
