To keep up with the fast pace of releases and the speed of DevOps, organizations need accurate and automated security testing tools that can easily scale and produce actionable results.
Historically, AppSec programs were characterized by the use of Static Application Security Testing (SAST) tools which analyze the code or binary itself, and Dynamic Application Security Testing (DAST) tools that simulate attacks to see how an application reacts. Fast forward to 2019 – While SAST is able to fit fast and iterative development processes, point-intime DAST is slow and manual, rendering it as unfit for DevOps-like processes. This is where the next-generation Interactive Application Security Testing (IAST) comes in.
IAST is a dynamic and continuous security testing solution that detects vulnerabilities on a running application by leveraging existing functional testing activities. IAST is designed to fit agile, DevOps and CI/CD processes. Unlike legacy DAST solutions, IAST does not introduce any delays to the software development lifecycle.
Here we take a look at the core differences between these three testing solutions to help to you decide which tools you need in your application security toolkit.
