The Software Development Life Cycle is important because it gives security officers a clear structure for how software should be planned, created, tested and maintained. When a team follows the SDLC, it becomes easier to identify risks early and make sure security is built into every stage. The SDLC also helps the organization stay consistent, follow policies, and reduce the chance of system failure. From the book, one key point is that SDLC improves the quality of software by creating repeatable steps. Another point is that it reduces long term costs because problems are fixed early. From, the video, one important idea is that each phase like planning, designing, and testing allows the security officer to check for vulnerabilities. Another helpful point is that the SDLC creates documentation, which helps with audits and accountability. Overall, the SDLC helps protect the systems, data and users.
