What is Dynamic Application Security Testing (DAST)?

Dynamic Application Security Testing (DAST) is a method of security testing in which a running instance of an application is actively tested and probed using real traffic and requests: it contrasts to Static Analysis (SAST) testing, which performs “offline” analysis of the source code. Often referred to as ‘black box testing’ DAST tools do not have direct access to any server-side code, and will attempt to identify potential vulnerabilities within the application using much the same methods and access perspective as a manual, real-world hacker would – via its public interface.

DAST mirrors the way that a penetration tester would approach an attack, in that first it identifies injection points (paths or pages that are designed to receive and process data – such as contact forms) and then sends payloads (crafted sets of data designed to permit malicious behaviour) to an application, before analysing the response.

How does DAST work?

Dynamic Application Security Testing (DAST) works by acting in the manner of a malicious hacker in order to find any potential vulnerabilities in your applications.

The crawler combines traditional web scraping with a browser-based crawler which implements artificial intelligence to mimic typical application user behaviour. By simulating the processes which hackers use to interfere with your systems and applications, our DAST tool ensures maximum coverage and accuracy.

Common vulnerabilities detected during the web application scan include; Injection flaws such as SQL, NoSQL, XML, Code, and Command injection, Cross-Site Scripting and hundreds of other vulnerability classes arising from insecure code which can cause serious issues for your business.

Why use a DAST tool?

DAST should be used as an integral part of your security processes to uncover a wide range of web application vulnerabilities and can be used alongside an array of other testing tools and systems in order to maximise your security. By incorporating DAST into your testing processes you can help cover your applications from external attacks by discovering potential vulnerabilities and removing these before they can be exploited.

Most frequent questions and answers about Dynamic Application Security Testing (DAST)

Dynamic Application Security Testing (DAST) is a security approach used to evaluate the security of your web environments, APIs, and applications. DAST (also referred to as black-box testing) simulates real-world attack scenarios by sending various inputs and HTTP requests to the application and then analysing the responses to identify potential security issues. These tools are particularly effective at detecting common web application vulnerabilities like cross-site scripting (XSS), SQL injection, security misconfigurations, and more.

A big benefit of DAST tools is that they are versatile and suitable for different tech stacks since they are language-independent.

They evaluate not only individual components but the entire application and its interconnected systems, making it easier to pinpoint potential risks. DAST also plays a crucial role in validating permissions, guaranteeing that privilege levels are properly isolated.

Security flaws within networks and applications can generally fall into two categories: “configuration flaw” or “software/hardware bug”. Many of the most devastating security issues, including those well-known flaws with a CVE identifier and even a catchy name and logo, are almost always a software bug introduced during development. Known vulnerabilities are relatively easy to discover and resolve since a clear and blueprint exists for detecting the vulnerability that is mostly the same across all vulnerable systems. For example, a Microsoft Windows server with a publicly disclosed vulnerability will have the same vulnerability across any network the same vulnerable version is installed in, the detection and exploitation of the flaw will largely be the same in each case.

Conversely, vulnerabilities in bespoke systems such as your web applications and websites are opaque and cannot be detected in the same way. To solve this challenge Dynamic Application Security Testing (DAST) is needed.

AppCheck performs online reconnaissance to gather information and also maps out the application using a sophisticated crawling engine. The crawler combines traditional web scraping with a browser-based crawler which implements artificial intelligence to mimic typical application user behaviour.

The “Mapped Attack Surface” enumerated during the initial phases of the scan, is then subject to methodical security testing. Typically, the assessment process works by taking each user supplied data component, such as a form field of query string parameter, then modifies it to include a specific test case before submitting it to the server. Based on the applications response, further test cases are then submitted through the same method to confirm the vulnerability.
