Which of the following places security at the forefront of development efforts but is not considered a software development method itself?

SecDevOps, or Secure Development Operations, emphasizes the integration of security practices within the DevOps process, ensuring that security is considered at every stage of the software development lifecycle. This approach focuses on embedding security into DevOps practices, to improve collaboration between development, operations, and security teams. While it is not a standalone software development method like Agile, Spiral, or Waterfall, it influences those methodologies by promoting security as a core component throughout the development process.

In contrast, Agile, Spiral, and Waterfall are formal methodologies or frameworks for developing software. Agile focuses on iterative development and flexibility, Spiral emphasizes risk assessment at different stages, and Waterfall follows a linear and sequential design approach. While these methods can incorporate security practices, they do not prioritize security in the same integrated way that SecDevOps does. Consequently, SecDevOps stands out for putting security at the forefront without being classified as a development method itself.
