Advanced DAST Techniques

Authenticated scanning reveals vulnerabilities in protected application areas. Modern DAST tools maintain authentication state through complex flows, handle multi-factor authentication, and can even navigate OAuth or SAML workflows. This capability ensures comprehensive coverage of applications where most functionality requires authentication.

Business logic testing through DAST continues evolving. Tools now understand shopping carts, payment flows, and multi-step processes. They can identify price manipulation, race conditions, and workflow bypasses. Some advanced tools allow scripting custom business logic tests that understand application-specific constraints.

API security testing has become a DAST specialization. Tools parse API definitions, understand RESTful conventions, and generate appropriate test cases. They test for authentication bypasses, parameter pollution, and method confusion. GraphQL-aware tools understand schema introspection and test for query depth attacks or information disclosure through error messages.
