Secure Development Lifecycle (SDL)

The Secure Development Lifecycle (SDL) is a structured process that helps software developers build secure and reliable software from the start. It includes steps like planning for security requirements, reviewing code for vulnerabilities, testing for security issues, and fixing potential problems before release. The goal is to prevent security flaws, reduce risks, and protect users’ data throughout the software’s development and maintenance, much like quality checks in manufacturing but focused on security. Implementing SDL helps ensure that security considerations are integrated into the software at every stage, resulting in safer and more trustworthy products.
