DevSecOps is an extension of the DevOps approach that integrates security practices into every phase of the software development lifecycle. It emphasizes the collaboration between development, operations, and security teams to ensure that security is a shared responsibility. DevSecOps aims to embed security measures early in the development process, automate security testing, and continuously monitor for vulnerabilities. This approach ensures that applications are not only developed and deployed efficiently but also remain secure against threats, reducing the risk of security breaches and enhancing overall software quality.
