The document discusses the rise of DevSecOps and its importance for software development. It notes that existing security solutions are no longer adequate due to the speed of modern development, and that security has become a bottleneck. DevSecOps aims to integrate security practices into development workflows to enable continuous and real-time security. It outlines how security responsibilities have evolved from separate teams to being shared among developers, and how tools have progressed from periodic testing to continuous monitoring and automation. The document argues that DevSecOps is necessary now given the costs of data breaches and risks of vulnerabilities in open source components.
