SAST (Static Application Security Testing) and DAST (Dynamic Application Security Testing) are complementary approaches to identifying vulnerabilities in software applications. SAST is a white-box testing method that analyzes source code, bytecode, or binary code for security flaws without executing the program, allowing developers to detect issues early in the development cycle. In contrast, DAST is a black-box testing method that evaluates the application in its running state by simulating external attacks to identify vulnerabilities that only appear during execution. While SAST provides detailed insights into the code and helps ensure coding standards, it requires access to the source code and may produce false positives. DAST, on the other hand, does not require source code access and can find runtime vulnerabilities, but it is typically performed later in the development process and may miss internal flaws. Together, these methods provide a comprehensive security assessment by addressing both code-level and runtime vulnerabilities.
