Secure SDLC
Definition
A Secure Software Development Lifecycle (Secure SDLC) is a process that integrates security-focused activities and tools into every phase of the standard software development lifecycle. The goal is to build security into the software from the beginning, rather than trying to add it on at the end.
Why It Matters
Building security in from the start ("shifting left") is far more effective and less costly than trying to fix vulnerabilities discovered late in the process or after a product has been released. A secure SDLC helps create more resilient and secure software.
Contextual Example
A secure SDLC includes activities like security training for developers, threat modeling during the design phase, using static code analysis tools during development, performing penetration testing before release, and monitoring for vulnerabilities after deployment.
Common Misunderstandings
- It is about making security a shared responsibility of the entire development team, not just a separate security team.
- DevSecOps is a related concept that emphasizes integrating security into the DevOps culture and pipeline.
