DevSecOps integrates security into the DevOps pipeline, fostering a culture of shared responsibility for security among development, operations, and security teams. Key principles include automating security testing throughout the development lifecycle, implementing security as code, embracing continuous monitoring, and integrating security considerations into every stage of the software development process. DevSecOps aims to proactively identify and remediate security vulnerabilities, reducing the risk of security breaches and ensuring the delivery of secure and resilient applications.
