DAST – Dynamic Application Security Testing

Table of Contents

What is Dynamic Application Security Testing?

Dynamic application security testing or DAST is a process that actively investigates running applications with penetration tests to inspect possible security vulnerabilities. Many mission-critical business processes are powered by web applications from public-facing e-commerce stores to internal financial systems, and the web applications also enable dynamic business growth which often harbor potential weakness which is left and undermedicated. This leads to a damaging and costly data breach.

Dynamic application security testing tools detect vulnerabilities in a running application by injecting malicious payloads to inspect any potential faults which allow for attacks such as SQL injections or cross-site scripting XSS. DAST tools also provide help to detect runtime flaws that SAST are not able to find. It also allows a list of the principal vulnerabilities scanners.

How do Dynamic Application Security Testing tools work?

DAST tools allow the automated review of a web application by testing all the access points as they communicate through the frontend. These DAST tools simulate malicious user actions and emulate any random movements that can be completed by complex test cases referred by an operator or interactions with the third-party systems such as email registration validation or SMS validation code. The calls, which also include web cryptography API and keychain will be intercepted and collected for the vulnerabilities to determine if each piece is acting as it should be or not.

Dynamic Application Security Testing Tools are helpful for detecting:

How to overcome the limitations of DAST?

Dynamic application security testing covers different areas which SAST does not reach and vice versa. In a comprehensive testing strategy, it should be mobilized on top of the manual reviews.

The security solution should be put in place with different parts of the lifecycle of an application. Consider production environment security tools and other non-scanners if you plan to use DAST pre-production.

Why do you need a DAST Tool?

Web application attacks are a significant threat to businesses of all kinds, and one of the common web-based attacks is SQL injection. This can gain control over a company’s web application database entirely by inserting arbitrary SQL code into the database query.

Hackers are will to target content management systems because they can harbor a concentration of vulnerabilities that are discovered and get easily exploited again and again. When a web application attack is in progress, then the security team may not inspect it for some time, but the attackers gain free reign to wreak such havoc as possible.

For businesses, even unskilled hackers can launch these kinds of attacks with the prospect of lucrative paydays. They mainly look for easily exploitable vulnerabilities in a web application like those found in the OWASP top 10. DAST tools operate in a way that provides security and development teams timely visibility into the action or behavior and potential weakness which could be exploited before an enterprising hacker and capitalize on them.

Conclusion

Businesses are increasingly deploying dynamic application security testing tools to address the growing threat. These tools work as a part of a more security forward approach for web application development. Dynamic application security tools provide insight into how the web application behave when they are in production and enable the business to address potential vulnerabilities before a hacker uses them to plan an attack. Web application evolves then dynamic application security tools solutions continue to scan to promptly identify and remediate emerging issues before developing any serious risks and issues.
