the development language (if the development team programs the application in one language, the SAST tool should scan that language).
SAST tools are typically selected with consideration of: SAST tools typically include a wide range of known errors out of the box, and additional issues can be defined as needed and added to the test regimen. The tool searches the static code line by line and instruction by instruction, comparing each against an established set of rules and known errors. SAST tools work by scanning code at rest (no human or program executes the code). This process can include everything from indentation to variable naming conventions and any other formatting related to the way developers write code. Development teams regularly use SAST tools to enforce compliance with established coding formats and standards. This method is a form of white box testing - its tools sometimes are called vulnerability checkers - that looks for problems in the code.Ī SAST tool, for example, might identify weak random number generation code, find potential buffer overflows, spot SQL injection possibilities, flag cross-site scripting flaws and identify other potential trouble spots that malicious actors could exploit.
SAST comprises the tools and technologies designed to check code for flaws and vulnerabilities. In actual practice, it takes a variety of properly employed tools to create a comprehensive security testing environment for application development teams.
Each brings value to security testing, but none alone are enough to ensure complete application security. Combines SAST and DAST techniques seeks the best benefits of both technologies.Įach of these technologies has specific demands and limitations.
A development team might employ multiple SAST tools to support various languages or development platforms. Allows developers to catch common flaws before a build is compiled. Static application security testing (SAST).That said, the three major types of security testing technologies that developers rely on to help identify security flaws before software releases are: Ultimately, it will be difficult - and perhaps impossible - to find a single tool that's a complete answer. Evaluate features, usability, cost, vendor support and so on. Development teams should select security testing tools using the same criteria they would use for other components in a CI/CD pipeline.
