SAST vs. DAST: What’s the best method for application security testing?

High profile security breaches are leading to heightened organizational security concerns. Firms around the world are now observing the consequences of security breaches that are becoming more widespread and more advanced. Due to this, firms are ready to identify vulnerabilities in their applications and mitigate the risks.

Two ways to go about this are static application security testing (SAST) and dynamic application security testing (DAST). These application security testing methodologies are used to find the security vulnerabilities that make your organization’s applications susceptible to attack.

Which one is right for your organization?

The two methodologies approach applications very differently. They are most effective at different phases of the software development life cycle (SDLC) and find different types of vulnerabilities. For example, SAST detects critical vulnerabilities such as cross-site scripting (XSS), SQL injection, and buffer overflow earlier in the SDLC. DAST, on the other hand, uses an outside-in penetration testing approach to identify security vulnerabilities while web applications are running.
