US Patent 11397813 System and method for verifying a regex group

Disclosed is a method and system for verifying a regex group. The method comprises verifying of a regex group by creating a flow id through a processor for the regex group when source reaches the sink. The flow id is used for tracking the flow of the regex group. The processor checks in case the flow id is a previously tested flow id. When the flow id is not the previously tested flow id, the processor passes one or more run tasks through a processor forming a queue. The processor tests for one or more vulnerabilities to be associated with the regex group based on the passing, wherein the testing is used to qualify the regex group as a valid regex group.
