DevSecOps is an approach that implements security practices throughout the development lifecycle from design to deployment. It aims to address security vulnerabilities early on. Key aspects include integrating security testing into continuous integration/delivery pipelines, implementing automation, and ensuring collaboration between developers, security teams, and operations from the beginning. Benefits include enhanced collaboration, increased speed and agility, and better quality control and threat detection. Limitations include reliance on open communication and acceptance across teams as well as some security tools not being compatible with continuous integration approaches.
