Interactive application security testing (abbreviated as IAST) [1] is a security testing method that detects software vulnerabilities by interaction with the program coupled with observation and sensors. [2] [3] The tool was launched by several application security companies. [4] It is distinct from static application security testing, which does not interact with the program, and dynamic application security testing, which considers the program as a black box. It may be considered a mix of both. [5]
