What does "secure software development lifecycle" (SDLC) entail?

The concept of the "secure software development lifecycle" (SDLC) refers to a systematic approach that incorporates security measures and considerations throughout the entire software development process. This ensures that security is not an afterthought but an integral part of each phase, from planning and design to implementation, testing, deployment, and maintenance.

By integrating security practices into the SDLC, developers can identify and mitigate potential vulnerabilities early in the process, which helps in building more resilient software systems. This proactive strategy aims to reduce risks associated with security breaches and to streamline the overall development process by reinforcing security at each step.

This choice accurately describes the essence of what a secure software development lifecycle encompasses, highlighting the importance of embedding security within development practices rather than addressing it solely at the end or as a separate entity.
