Abstract
Electronic communications passing through a communication gateway or similar device for an enterprise can be monitored for indicators of malicious activity. When potentially malicious activity is identified, a user-based inquiry can be employed to identify potential sources of the malicious activity within the enterprise network. More specifically, by identifying a user that sourced the communication, instead of or in addition to a network address, devices within the enterprise network associated with the user can be located, analyzed, and remediated as appropriate.
