This document discusses the concepts of DevSecOps at a high level. It begins with a brief history of development methodologies, from Waterfall to Agile, and how Ops became a bottleneck. This led to trends in Agile Operations and collaboration between Dev and Ops, known as DevOps. DevSecOps expands this to incorporate security. It discusses DevSecOps in terms of culture, processes, and technologies, with a focus on secure software development lifecycles, security pipelines, requirements management, and automated testing and monitoring. The goal of DevSecOps is to enable organizations to deliver inherently secure software at DevOps speed.
