DAST: Dynamic Application Security Testing in Cybersecurity
DAST stands for Dynamic Application Security Testing. Dynamic Application Security Testing probes running applications for vulnerabilities by sending crafted requests and analyzing responses. DAST tools act as external attackers, testing for injection flaws, authentication weaknesses, and configuration errors without access to source code.
How DAST Is Used in Cybersecurity
Penetration testers use DAST tools as part of web application assessments to find runtime vulnerabilities. Security engineers schedule automated DAST scans against staging environments before production deployments. SOC analysts correlate DAST findings with production alerts to validate whether known weaknesses are being targeted.
