SDLC is a process followed for a software project, within a software organization. For the past decade, the BSIMM has tracked the security activities performed by more than 100 organizations. Security itself is a continuous process of testing, upgrading, patching, maintaining & remediation tasks to ensure that software continues to remain secure and available. Secure Software Development Life Cycle (S-SDLC) means security across all the phases of SDLC. A software development life cycle (SDLC) is a framework for the process of building an application from inception to decommission. The life cycle defines a methodology for improving the quality of software and the overall development process. In general, SDLCs include the following phases: In the past, organizations usually performed security-related activities only as part of testing—at the end of the SDLC. Other related methodologies are Agile Model, RAD Model, Rapid Application Development and Prototyping Models. The SDL helps developers build more secure software by reducing the number and severity of vulnerabilities in software, while reducing development cost. Cool new features aren’t going to protect you or your customers if your product offers exploitable vulnerabilities to hackers. In a Secure SDLC, provide secure coding guidelines to the development team. However, the term systems development life cycle can be applied more universally, not only across projects where software is the primary deliverable, but other types of IT solutions that involve hardware, network, and storage components, or even business or mechanical systems - where software may only be a small part of the overall solution.
