Systems And Methods For Improved Detection Of Network Attacks

Abstract: A computing system for detecting cyber-attack events is described. The computing system executes a roughness profiling engine and a cyber -attack detection model. The roughness profiling engine is configured to.receive a plurality of payment transaction authorization request messages and generate a plurality of groups, each group of the plurality of groups associated with a 'first data field. The roughness profiling engine is also configured to profile the plurality of groups into a plurality of sub-groups, each sub-group of the plurality of sub-groups associated with a Second data field and calculate a respective cumulative metric from the payment transaction authorization request messages associated with one of the plurality of sub- groups. Hie roughness profiling engine is further configured to determine a roughness ratio value, generate a set of feature inputs based on the roughness ratio value, and transmit the set of feature inputs to the cyber-attack detection model.
