What is Static Application Security Testing (SAST)?
Static analysis, often known as static application security testing (SAST), is a testing approach that examines source code to discover security flaws that render the apps used by your company vulnerable to attack. Before the code is compiled, an application is scanned by SAST. White box testing is another name for it.
SAST reduces the security risks in the application at below three phases of the software development life cycle (SDLC), at a high level.
1) Engineers who are creating and programming the application use SAST scans into their development process and tooling during development.
2) Security teams utilise SAST technologies to check apps for security flaws after development and before production deployment.
3) Applications are released into production by going through the DevOps process, which results in production deployment. To guarantee that vulnerabilities are found before getting into production, SAST is also used at this phase.

How does SAST function?
SAST happens relatively early in the software development life cycle (SDLC) since it may be done without a functioning application and does not involve running any code. It enables developers to swiftly address problems without halting builds or introducing vulnerabilities into the application's final release. Vulnerabilities may be found early in the development process.
Importance of SAST
SAST assists enterprises in very early SDLC vulnerability remediation. Before it is released to production, developers analyse the code at this stage to determine which line has the vulnerability so that they may patch it and retest.
Benefits of SAST
1. Finding weaknesses in the source code is one of its main goals. They aid security teams and developers in finding security flaws that other security technologies might miss.
2. Finding weaknesses in the source code is one of its main goals. They aid security teams and developers in finding security flaws that other security technologies might miss.
3. Nobody wants to go through the laborious process of examining the source code to identify the problematic lines of code. With the help of this tool, you may find out where in the line of code the error is and what has to be done to fix it.
