What is DAST?

Dynamic application security testing (DAST) is a method of Application Security testing that inspects an application while it’s running, without prior  knowledge of the application’s internal interactions or designs at the system level, and with no access or visibility into the source program.

This “black box” testing looks at an application from the outside in, examines its running state, and observes its responses to simulated attacks made by the tool.

How does DAST work?

DAST works by replicating automated attacks on an application, disguising as a malicious attacker. The goal is to find outcomes or results that were not expected and could therefore be used by attackers to compromise an application.

Since DAST tools don’t have any internal information about the application or the source code of the application , they attack just as an external attacker would—with the same limited prior knowledge and information about the application.

Why is DAST essential for every business development cycle?

  • DAST is critical because developers do not have to rely solely on their own knowledge when developing applications. By conducting DAST during the SDLC, they can detect vulnerabilities in an application before it’s deployed to the public.
  • If these vulnerabilities are left abandoned and the app is deployed as such, this could lead to a data breach or an attack, resulting in major financial loss and damage to your brand reputation.
  • Human error will inevitably play a part at some point in the Software Development Life Cycle (SDLC), and the sooner a vulnerability is caught during the SDLC, the cheaper it is to fix.

Tips to improve DAST for your security cycle using our tools

Use DAST early and often for best result :

  • Companies produce maximum benefit from a DAST solution when they leverage it to identify potential weaknesses and security flaws  in their web applications, particularly client-critical applications, as early as possible in the software design lifecycle.

Enable effective collaboration with DevOp:

  • DAST tools help you categorize and prioritize the vulnerabilities you discover, but to make certain proper resolution, you must then effectively hand them off to your colleagues in the DevOps team.
  • DAST works best as part of a comprehensive approach to web application security testing

What is a DAST tool that is well-suited for developers?

Ambisure DAST tool provides automated dynamic application security testing so you can scan and fix exploitable web application vulnerabilities and security flaws.
Typically, DAST is done after production since it is emulating attacks on a running application; but by making the decision to “Shift DAST left” (moving DAST earlier in the process of development) you’re able to detect vulnerabilities sooner, which saves time and money. We include pre-built scan policies, balancing the need for speed with your organizational requirements.
We also include an incremental scanning feature, which allows you to rapidly assess vulnerabilities in only the areas of the application that have changed.

Our tool allows you to:

  • Secure DevOps with automated DAST
  • Manage AppSec risk at scale
  • Achieve compliance with major data security regulations
  • Shift DAST left
  • Crawl modern frameworks and APIs
  • Build a stronger AppSec program

Advantages of our DAST test solution

  • Mimic the actions of an actual attacker to uncover vulnerabilities not found by other testing techniques.
  • Run tests on applications developed in any language – JAVA/JSP, PHP and other engine-driven web applications.
  • Provide development and QA teams with a report on critical vulnerabilities along with information that lets them recreate the flaws.
  • Fix issues more quickly with detailed remediation information.
  • Develop long-term strategies for improving application security across your software using guidance and proactive recommendations from our experts.
  • Technology independent
  • Low false positives
  • Identifies configuration issues

DAST: One Piece of Your Application Security Puzzle

When DAST is included as part of the Continuous Integration/Continuous Development (CI/CD) pipeline, this is referred to as “Secure DevOps,” or “DevSecOps.”

In a modern DevOps practice, security and developer teams need testing solutions that help secure applications without slowing down development. In this sense, DAST is a powerful tool. In fact, after SAST, DAST is the second largest segment of the AST market.

    frequently asked questions

    • DAST, sometimes called a web application vulnerability scanner, is a type of black-box security test. It looks for security vulnerabilities by simulating external attacks on an application while the application is running. It attempts to penetrate an application from the outside by checking its exposed interfaces for vulnerabilities and flaws.

    • DAST test, is an application security solution that can help to find certain vulnerabilities in web applications while they are running in production.
    • DAST demonstrates the attack and provides a proof of exploit for every risk uncovered. This gives developers context, validating that the vulnerabilities really exist and making it easy to test patches without running another scan.
    • The key difference between SAST and DAST is that DAST is done from the outside looking in. It is a process that takes place while the application is running. Attempts are made to penetrate the application in a variety of ways to identify potential vulnerabilities, including those outside the code and in third-party interfaces. Source code, byte code, and binaries are not required with DAST, and it is easier to use and less expensive than SAST tools.

    • DAST can determine different security vulnerabilities that are directly linked to the operational deployment of an application.
    • No need to access the code as it helps to find different vulnerabilities in the web applications while they are running in the production environment.
    • It supports a testing team in finding the vulnerabilities which exist outside the source code and in the third–party application interfaces.
