What Is the Difference between DevOps and DevSecOps?

DevOps is a methodology aiming at establishing closer collaboration between programmers and system administrators in the software development process. A DevOps engineer is a specialist working on the intersection of these two fields. A DevOps engineer's primary objective is to take the predictability, efficiency, and security of software development to the highest level possible. DevSecOps is a further development of the DevOps concept that, besides automation, addresses the issues of code quality and reliability assurance.
