SYSTEMS AND METHODS FOR DETECTING MALICIOUS COMPUTING EVENTS

The disclosed computer-implemented method for detecting malicious computing events may include (i) determining, for multiple computing events detected within an enterprise, an initial disposition score for each computing event based on currently- available security information, (ii) determining an initial classification of each computing event as malicious or non-malicious by comparing the initialdisposition score of each computing event with a threshold disposition score, (iii) for each computing event, determining (a) an updated disposition score based on new security information (b) an updated classification, (iv) calculating a degree to which the threshold disposition score correctly identifies malicious computing events by determining a frequency with which the initial classificationof each computing event matches the updated classification of the computing event, and (v) adjusting the threshold disposition score based on the degree to which the threshold disposition score correctly identifies malicious
