For comprehensive application security testing, combining Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) provides the best coverage:
* Static Application Security Testing (SAST):
* Source Code Analysis: Scans the source code to identify vulnerabilities such as code injection, buffer overflows, and insecure APIs.
* Early Detection: Allows developers to fix vulnerabilities early in the development lifecycle.
* Dynamic Application Security Testing (DAST):
* Runtime Analysis: Tests the running application for vulnerabilities, including issues related to configuration, authentication, and authorization.
* Real-World Attacks: Simulates real-world attacks to identify how the application behaves under different threat scenarios.
* Combined Approach:
* Holistic Security: Using both SAST and DAST provides a thorough security assessment, covering both code-level and runtime vulnerabilities.
* Comprehensive Coverage: Ensures that both internal code issues and external attack vectors are addressed.
