Which approach merges traditional phased reviews with agile methodologies to enhance security in software development?

The approach that effectively merges traditional phased reviews with agile methodologies to enhance security in software development is DevSecOps. This methodology integrates security practices directly into the DevOps process, ensuring that security is a key consideration throughout all phases of development, from initiation to deployment.

In a typical DevSecOps framework, security checks and protocols are embedded into the continuous integration and continuous delivery (CI/CD) pipelines, allowing teams to identify vulnerabilities and security weaknesses early in the development cycle. This proactive stance helps to address security concerns in a more efficient manner, reducing the risk of vulnerabilities that could emerge later in the development process.

By emphasizing collaboration among development, security, and operations teams, DevSecOps creates a culture of shared responsibility for security. This contrasts with traditional models that often treat security as an afterthought, performed during a specific review phase after development has largely completed. The integration of security within agile methodologies enhances the overall security posture of software applications while maintaining the speed and flexibility characteristic of agile development.
