DevSecOps with Microsoft Tech discusses how security fits within DevOps practices. DevOps aims to improve quality and speed of delivery through collaboration between development and operations teams. Security is often an afterthought but needs to be integrated throughout the software development lifecycle. DevSecOps ensures security controls are implemented at every stage to improve quality, security and compliance outcomes. Key principles like least privilege, defense in depth and auditing still apply, but are implemented more frequently and at a more localized scale through DevOps practices.
