Cyber Resilience in Action: Dynamic Application Security Testing Best Practices

In the ever-evolving landscape of cyber threats, the call for enhanced cyber resilience is more apparent than ever. One widely embraced measure towards this end is the proactive performance of Dynamic Application security testing (DAST). DAST is the systematic uncovering of vulnerabilities that cannot be identified in the static phase of the software development life cycle (SDLC). This methodical process heightens overall defense against potential cyber attacks or system compromises.

The key to achieving strong cyber resilience is to be proactive rather than reactive in fortifying your cyber defenses. What this implies is that your security measures should work predictively, identifying possible flaws and vulnerabilities before they are explored by malignant entities. DAST accomplishes this in many ways.

DAST: Brief Intro and Its Importance

DAST, also known as black-box testing, is a security testing method that checks a running application from the outside in. It inspects all the exposed interfaces, ensuring they adhere strictly to security standards, and probes for vulnerable points from where attacks like SQL Injection, XSS, CSRF, etc. could be launched.

In today's digital era, application security is paramount. As organizations digitize their operations, they also expose themselves to an array of cyber threats. It, therefore, becomes incumbent on organizations to protect applications, especially those that have substantial data moving through them, or those that store and process sensitive data.

Best practices for effective DAST

Effective DAST can be achieved by implementing several best practices. The process should ideally be integrated into the SDLC so that every application developed by the organization is subject to it. Let's explore some of these best practices.

1. Integrate DAST early into the Software Development Life Cycle

One of the essential requirements for successful DAST is integrating it early in the Software Development Life Cycle (SDLC). This is often referred to as "Shifting Left". The benefit of such a strategy is that any vulnerabilities or flaws can be detected early on when they are easier (and cheaper) to fix.

2. Prioritize vulnerabilities

Not all vulnerabilities are created equal. Some might cause minor inconveniences, while others could lead to significant breakdowns or data breaches. Hence, it's necessary to employ Vulnerability assessment strategies that prioritize these vulnerabilities based on the potential damage they could inflict if exploited.

3. Regularly update your DAST tools

As mentioned earlier, cyber threats are constantly evolving and becoming more advanced. As such, your DAST tool should also adapt to these changing landscapes. Regular updates ensure your Application security testing tools are abreast with the most recent vulnerabilities and are equipped to deal with them effectively.

4. Adopt a layered approach

DAST should not be the only line of defense for your application but should be used in conjunction with other security testing methods. This layered approach ensures maximum security by covering all conceivable areas where cyber threats might pose danger.

Automating DAST for optimum results

With the complex and constantly evolving threat landscape, automating DAST is becoming increasingly pertinent. Automation not only speeds up the process but also ensures comprehensive coverage and eliminates human error. Tools that allow for DAST automation should be leveraged, ideally those that integrate smoothly into the existing software development process and tools.

Automated DAST tools should support CI/CD integrations, provide actionable reports, and have competent support to address any challenges that may arise during the DAST process.

Keep in mind that while automation can yield top-notch results, it's not a magic bullet. It should go hand in hand with manual testing for complete coverage.


In conclusion, sustaining cyber resilience demands vigilant and proactive security measures, among which DAST ranks highly. By integrating DAST early into the SDLC, prioritizing vulnerabilities, regular updates of DAST tools and adopting a layered approach in conjunction with automated DAST, organizations can protect their vital applications effectively.

Cyber resilience is a journey, not a destination. Hence, a robust security posture demands continual assessment, adaptation, and evolution to stay aligned with the growing sophistication of cyber threats. Deploying DAST effectively is a significant step in this resilient journey and serves as a potent defense mechanism against unrelenting cyber adversaries.
