Static Application Security Testing (SAST) is a method focused on evaluating the integrity of an application's source code or binaries to identify security vulnerabilities before the software is executed. This type of testing is conducted early in the software development lifecycle, allowing developers to find and remediate issues without having to wait for the application to be fully developed or deployed.

SAST tools analyze the application's code structure, data flow, and control flow to detect potential security flaws such as buffer overflows, SQL injection vulnerabilities, and more. By examining the code statically, SAST helps ensure that vulnerabilities are identified and addressed early on, which can be more cost-effective and lead to more secure coding practices.

In contrast, analyzing user behavior or physical security measures does not directly relate to identifying vulnerabilities within the application itself. Similarly, network traffic analysis is concerned with monitoring and protecting against external threats, which is outside the purview of what SAST aims to achieve.
