Interactive Application Security Testing (IAST) is a technology for automatically identifying and diagnosing software vulnerabilities in applications and APIs. IAST is not a scanner, and instead continuously monitors your applications for vulnerabilities from within by running throughout your development lifecycle and instantly alerts you through the tools you're already using in development and test.

Why do we need IAST? The problem is simple, we have a massive "scale" problem in application security. We have a very limited number of security experts to apply to the problem, but there are almost 20 million developers worldwide. Running tools such as SAST, DAST, and SCA requires scarce expertise.Dzone_IntroductiontoIAST

Read this DZone Article to learn how IAST:

  • Prevents vulnerabilities during deployment
  • Detects attacks and prevents exploit in production
  • Custom Code Security Testing
  • Open Source Security Testing
