Analysis of Dynamic Application Security Testing and A Comparison of Its Benefits to SAST

Abstract

By simulating attacks on the applications, DAST is a technique for dynamic application security testing that is used to identify weaknesses in web-based applications. The goal of this type of approach is to find application errors by reviewing the application from the outside in. To do this, the developers will act like a malicious intruder and launch various attacks against the application to see if they can break the code or not. On this basis, the programmers can identify the application's and the code's weak points and use stronger, more complex algorithms that are difficult for an attacker to defeat. In this manner, the code that is created will be effective and offer adequate security for web-based applications. After the DAST scan is finished, the results will be compared to what was anticipated, and if there are any discrepancies, the vulnerabilities will be found and fixed. It is one of the black box testing techniques which is used to evaluate the application from attacker’s view point without bothering about the source code or architecture of the application or software. Another advantage of DAST is to identify the configuration errors, etc and also find out the vulnerabilities against the SQL injection and cross scripting related errors.
