DevOps is a union of development and operations whereas DevSecOps is integration of security in DevOps framework. It ensures the secure workflow of DevOps by selecting the right security tools and parameters. DevSecOps and DevOps, both play a significant role in an environment where software upgrades are usually executed several times daily and obsolete security models can’t sustain it. Where DevOps focuses only on effective deployment of upgrades, DevSecOps address the security concerns along with deployment. The Devops process: Continuous integration (CI) – merges code changes to ensure the most recent version is available to developers
