What is the primary function of Static Application Security Testing (SAST)?

The primary function of Static Application Security Testing (SAST) is to analyze source code for vulnerabilities. This type of testing allows developers to identify security flaws early in the development cycle, before the application is deployed and while it is still in the code form. By examining the source code or binaries, SAST tools can detect issues such as coding errors, insecure coding practices, and potential vulnerabilities that could be exploited by attackers.

SAST is particularly valuable because it provides feedback to developers about security weaknesses in their code without needing the application to be executed. Addressing these vulnerabilities during the coding phase helps reduce remediation costs and improves the overall security posture of the application. This proactive approach is essential in fostering a culture of security awareness throughout the software development lifecycle.
