How to run a SAST (static application security test): tips & tools

There are a number of different was to test the security of web applications, such as:

Dynamic application security testing (DAST) Interactive application security testing (IAST) Static application security testing (SAST) Software composition analysis (SCA)

This article focuses on SAST.

Static application security test

The static application security test (SAST) involves analyzing the source code of the application to find vulnerabilities present in it. Since SAST scans the code before it is compiled, it is a form of white-box testing.

SAST has been in practice for more than a decade. It allows developers to find security vulnerabilities in the earlier stage of the software development life cycle (SDLC). Also, SAST ensures conformance to secure coding standards without actually running or compiling the actual code.

How SAST helps in SDLC 

SAST is integrated into the very early stage of the software development life cycle (SDLC) since it does not require the code to be executed or compiled. This helps developers locate vulnerable code in the initial stages of SDLC.

Developers can then make any modification accordingly to fix the vulnerable code without breaking any builds.
