What is DAST and why is it important?

What is DAST in security testing?

DAST is short for “Dynamic Application Security Testing,” and it is a type of cyber security testing that is used to identify security vulnerabilities in web applications. It is important because it allows organisations to identify and address potential security vulnerabilities before they can be exploited by attackers. By doing so, organisations can reduce the risk of data breaches and other security incidents that could have a negative impact on their operations and reputation. Additionally, DAST can help organisations to comply with industry standards and regulations that require regular security testing of web applications.

what is the difference between DAST and SAST?

DAST and SAST are both types of cyber security testing, but they are used for different purposes and have some key differences. DAST, or Dynamic Application Security Testing, is a type of testing that is performed on a live web application, while SAST, or Static Application Security Testing, is performed on the source code of a web application.

One key difference between DAST and SAST is the way that they identify security vulnerabilities. DAST uses automated tools to simulate attacks on a live web application and identify potential vulnerabilities, while SAST uses specialized analysis tools to scan the source code of a web application and identify potential vulnerabilities.

Another key difference is the level of access that is required to perform the tests. DAST can be performed without access to the source code of a web application, while SAST requires access to the source code in order to be performed.

What are the benefits of DAST?

There are several benefits of using DAST, or Dynamic Application Security Testing, in cyber security. Some of the key benefits include:

  • can help organisations to identify and address security vulnerabilities in their web applications before they can be exploited by attackers. By doing so, organisations can reduce the risk of data breaches and other security incidents that could have a negative impact on their operations and reputation.
  • can be performed on a live web application, which means that organisations can identify and address vulnerabilities in real-time. This can help to ensure that the security of their web applications is maintained and kept up-to-date.
  • DAST is an automated process, which means that it is quick and efficient to perform. This can help organisations to save time and resources and to ensure that their security testing is performed on a regular basis.
  • can be integrated with other security tools and processes, such as SAST (Static Application Security Testing) and penetration testing, to provide a more comprehensive view of the security of an organisation’s web applications.
  • can help organisations comply with industry standards and regulations that require regular security testing of web applications. By using DAST, organisations can demonstrate that they are taking the necessary steps to protect the security of their web applications.

What are DAST tools?

DAST tools, or Dynamic Application Security Testing tools, are specialized software programs that are used to identify security vulnerabilities in web applications. These tools work by simulating attacks on a live web application and identifying potential vulnerabilities that could be exploited by attackers.

DAST tools typically use a combination of automated testing and manual analysis to identify vulnerabilities in a web application. Some common types of vulnerabilities that DAST tools can identify include SQL injection, cross-site scripting (XSS), insecure direct object references, and cross-site request forgery (CSRF).

Some examples of popular DAST tools include:

Acunetix
Burp Suite
IBM Security AppScan
HP WebInspect
Veracode

Organisations can use DAST tools to perform regular security testing of their web applications and to identify and address potential vulnerabilities before they can be exploited by attackers. This can help to ensure the security and integrity of the web applications and to protect against data breaches and other security incidents.

Conclusion

Overall, DAST and SAST are both important tools for identifying and addressing security vulnerabilities in web applications, and they are often used together as part of a comprehensive security testing strategy.
