DevSecOps enables seamless application security earlier in the software development life cycle, rather than at the end when vulnerability findings that require mitigation are more difficult and costly to implement. Having this DevSecOps mindset means more secure development, security testing, and continuous monitoring and protection in the CI/CD pipeline.
Because the goal of DevSecOps is to make security part of the software development workflow, this means everyone is involved in ensuring that applications are secure, not just the AppSec team. This means implementing secure coding best practices and testing automation, rather than “bolting it on” at the end of the life cycle. This is commonly referred to as “shifting security left” or simply “shift left.”
