Looking at Dynamic Application Security Testing

From all of the available application security testing strategies currently available in the market, the dynamic application security testing (DAST) method is usually used for evaluating the security posture of running applications. Similar to pentesting strategies from some angles, it helps in identifying specific security vulnerabilities, making it a crucial ingredient of any business’ security strategy, be it e-commerce firms or internal financial systems. 

The DAST approach is a part of the security-forward approach where precautionary steps are taken to avoid security compromises that could lead to loss of reputation or revenue. There are certain characteristics that must be kept in mind so that the right kind of security testing methods can be used for better web application development practices. 

What’s Important To Remember About Dynamic Application Security Testing?

The right application of the dynamic application security testing method with the associated tools will provide more holistic insights into web application vulnerabilities during the production phase for quick remediation. DAST is also known for its constant monitoring for potential security threats and vulnerabilities that can be detected and resolved before they’re exposed to hackers for a system breach. 

The first factor that benefits from periodic DAST procedures is the ability to ensure collaboration with the firm’s DevOps team. This will help in grading the vulnerabilities discovered based on the criticality and the associated priority of remediation, all of which is important information for the team. Therefore, DAST involves the integration of testing tools with the bug-tracking software which ensures that relevant information regarding the security issues is immediately available. The testing team will then be able to formulate the right steps and address security concerns on a priority basis with a DevSecOps mindset. 

The best timing for DAST is as early as possible in the software development lifecycle (SDLC), risking more costs, time, and wastage of resources as it gets delayed. The best results from the procedure come up when the DAST solution is implemented at the early stages of the development cycle for identifying potential vulnerabilities. At a later stage, detecting and resolving the issues will take up significantly more resources.  The more important the application is to the business operations, the more critical it is to engage in the early deployment of the DAST methodology. 

As an overall approach to web application security testing, DAST works efficiently to provide actionable insights at the right time. It works efficiently with other forms of AST, such as static testing, to understand the behavior of the web application. With static and dynamic application security testing (DAST) combined, you get both a quick picture of all the potential vulnerabilities in the source code and a real-time representation of a hacking attempt on a running application. This will allow the implementation of security strengthening measures once we’re able to visualize the hacker breaking into a specific area of the application early on in the SDLC. By using these approaches and tools such as a web application scanner, firms are highlighting the importance of security and utilizing the best practices for vulnerability detection and remediation. 

Why Are DAST Tools Crucial To The Testing Process?

DAST tools are implemented with the purpose of detection of security vulnerabilities in the production phase of the web application through actual simulation and further exploitation. Once this process turns up a security vulnerability, the DAST tools put out an alert that is automatically sent to the relevant teams for prioritizing based on its criticality. The overall process works to provide a holistic picture of the web application’s security posture with the added feature of constant monitoring for any new threats and/or weaknesses. Since the early utilization of DAST can help in detecting such issues quickly in the SDLC, companies benefit in terms of the resources spent on cyber risk management. 

The DAST process and its tools are also useful for helping businesses achieve the relevant compliance requirements and regulatory standards according to the industry and country laws. Most compliance standards are based on the OWASP Top Ten list of web application vulnerabilities as a benchmark standard, but the testing process in itself shouldn’t be limited to this approach as hackers are always discovering different attack methods. Some third parties also offer the services of vulnerability detection and leave it to the company to identify the topmost issues based on their subjective reasoning for remediation purposes. DAST solutions are also efficient in assisting development teams in identifying configuration errors or flaws and providing context in terms of the associated user experience problems when using the application. 

Dynamic application security testing (DAST) has various benefits and should be utilized periodically and efficiently with the help of security experts for best results. The cornerstone of every good security strategy is the timely visibility of potential security vulnerabilities that allows us to assess the application’s behavior in response to user needs.
