DevSecOps

DevSecOps is the integration of security practices within the DevOps process, creating a 'Security as Code' culture with continuous, flexible collaboration between release engineers and security teams.

Understanding DevSecOps

Definition

DevSecOps is a methodology that integrates security practices into the DevOps process, ensuring that security is built into the software development lifecycle from the beginning rather than being added as an afterthought.
