Dynamic Web Application Security Testing (DAST)

In this video, we explore Dynamic Application Security Testing (DAST), a crucial process for identifying security weaknesses and vulnerabilities in web applications. What is DAST? DAST is a web scanner used for non-functional testing to pinpoint security flaws. It communicates with web applications through the front-end to identify potential vulnerabilities and architectural weaknesses. DAST can be conducted manually or through automated tools. Why Use DAST? Conducts automated security reviews for regulatory compliance. Identifies vulnerabilities such as Cross-Site Scripting (XSS), SQL injection, and server configuration issues. Detects vulnerabilities in finalized products before release. Simulates realistic attacks to find weaknesses. Provides continuous scanning to discover and patch new vulnerabilities. How Does DAST Work? Automated Testing: Utilizes black-box testing methods to perform attacks and detect vulnerabilities through the web front-end. It involves sophisticated scans configured with host names, crawling parameters, and authentication credentials. Manual Testing: Fills in the gaps left by automated tools, identifying business logic errors, race conditions, and zero-day vulnerabilities that automated tools might miss. Types of DAST Tools: Commercial Scanners: Offer extensive features but often require purchase. Open-Source Scanners: Available for free, though with potentially limited features. Risks of DAST: Potential data overwriting or malicious payload injection; hence, it should be used in a non-production environment. Limited source code coverage; tools must be correctly configured based on the attack surface of the application. Cannot implement all variants of attacks for a given vulnerability. Limited understanding of dynamic content like JavaScript and Flash. Note that attackers also use DAST tools to find and exploit vulnerabilities. Conclusion: Dynamic Application Security Testing (DAST) is an essential tool for maintaining the security of web applications. By continuously scanning and identifying vulnerabilities, DAST helps organizations protect their applications from potential threats and comply with security regulations.
