How SAST will improve your overall security: Introduction

Application testing is a process that helps ensure the quality and security of your software applications, whether the application is for a mobile or desktop device. Of course, it’s easy to understand why evaluating and inspecting the security of an application can be beneficial. The testing process can be used to find bugs and vulnerabilities, as well as to assess the overall security status of an application.

There are several types of tests that can be performed on an application, with the most popular being SAST, DAST, and IAST, but Static Application Security Testing (SAST) is one of the most effective.

That is, SAST is a type of test that analyzes the source code of an application rather than its binary or executable files. Many online security platforms like Repair SAST they allow in-depth analysis of the application and can often find vulnerabilities that would otherwise be missed by other testing methods.

What is SATS?

As we mentioned earlier, SAST (Static Application Security Testing) is a type of security testing that scans your source code for vulnerabilities. This is in contrast to other forms of security testing, which focus on analyzing the behavior of running applications.

Regarding SAST, the test method can be used to find a wide variety of security issues, including SQL injection flaws, cross-site scripting (XSS) vulnerabilities and insecure coding practices that could lead to buffer overflows or attacks.

Therefore, most experts believe that SAST is an important part of any security program, as it can help find vulnerabilities that other types of tests might miss. For example, a web application firewall (WAF) will only be able to detect and block SQL injection attacks if the attacker uses a specific type of payload that the WAF is configured to look for. However, SAST can find SQL injection flaws regardless of the payload being used, as it analyzes the source code for insecure coding practices.

Comparing SAST with IAST and DAST

As we mentioned earlier, SAST is one of the three main types of application security testing. The other two are Interactive Application Security Testing (IAST) and Dynamic Application Security Testing (DAST).

In his approach, IAST it is similar to SAST in that it also analyzes the source code of an application. However, the IAST tools are generally used while the application is running to provide more accurate results. This can make IAST more intrusive than SAST, as it can interfere with normal application operation.

On the other hand, DAST is different from both SAST and IAST in that it focuses on analyzing the behavior of an application rather than its source code. DAST tools work by sending requests directly to the application and observing its response.

Benefits of SAST

There are many benefits of using SAST to improve the security posture of your application, including:

  • Improved overall security: SAST can find vulnerabilities that other types of tests might miss. This means that your applications will be generally more secure.
  • Reduction of false positives: Since SAST analyzes source code rather than binary or executable files, it is less likely to produce false positives than its counterparts.
  • Easier to use: many SAST tools are easy to use and do not require much training. This makes them ideal for organizations with somewhat limited resources.
  • Faster results: Unlike DAST and IAST, SAST tools can often find vulnerabilities much faster than other types of tests, such as manual code reviews.
  • Lower costs: SAST is typically less expensive than other types of testing, especially when compared to more intrusive methods like penetration testing.

The effect that SAST has on security

When it comes to testing the security of an application, SAST is an integral part of security assessment, as it can find vulnerabilities that testing methods might miss. Unlike other types of testing tools that can be used much later in the application’s software development lifecycle, SAST tools can test security from the moment the first few lines of code are written.

This is why SAST has an incredibly positive effect on security: it can help the development team fix the problem before it even becomes one. For the vast majority of developers and applications, it is much easier to patch a vulnerability in its early stages and fix the line of code where it occurs than it is to build a massive application only to rework the code later.


We can conclude that SAST is incredibly beneficial and should be considered an essential part of an application’s security assessment. It can also help find vulnerabilities that other types of tests (such as IAST and DAST) might miss, and is often faster and less expensive than its counterparts. So if you’re looking to improve the security of your applications, SAST is a great place to start.
