Frequently Asked Questions
What is a secure SDLC?
A secure SDLC embeds security activities into every phase of software development, from requirements and design to testing and deployment, so vulnerabilities are prevented early rather than patched after release.
What does shift-left security mean?
Shifting left means moving security tasks earlier in the development timeline, such as threat modeling at design and scanning on commit. Finding flaws sooner makes them cheaper and faster to fix.
How do I add security to each SDLC phase?
Add requirements and threat modeling early, code review and scanning during development, and testing before release. The Codelivly room is free and hands-on, showing how these activities fit together.
