What integrates security practices into every phase of the software development lifecycle?

The integration of security practices into every phase of the software development lifecycle is best represented by the approach known as DevSecOps, or SecDevOps. This methodology emphasizes the importance of incorporating security from the very beginning of the development process rather than treating it as an afterthought.

In a traditional development environment, security may be addressed at the end of the development cycle, which can lead to vulnerabilities and increase the risks associated with software deployment. However, DevSecOps promotes a culture where developers, security professionals, and operations teams collaborate closely, ensuring that security considerations are integrated throughout each phase of development. This proactive approach leads to the identification and remediation of security issues earlier in the cycle, ultimately resulting in more secure applications.

While the other approaches mentioned, such as DevOps and Agile, do focus on improving development workflows and efficiency, they do not inherently prioritize security as comprehensively as DevSecOps does. Continuous Integration, while valuable for automating testing and deployment processes, also falls short of incorporating security across the entire development lifecycle. DevSecOps stands out because it specifically aims to embed security deeply into the fabric of development processes, fostering a shared responsibility for security among all team members.
