Security Development Lifecycle (SDL)

The Security Development Lifecycle (SDL) is a structured process used by organizations to build secure software. It involves integrating security practices at every stage—from planning and design to coding, testing, and deployment. The goal is to identify and fix vulnerabilities early, reducing the risk of security issues after release. By following SDL, companies ensure their software is more resilient against cyber threats, protecting both users and data. Overall, it’s a proactive approach to embed security as a fundamental part of software development rather than an afterthought.
