Techniques for forensic tracing of suspicious activity from cloud computing logs

Abstract

A system and method traces suspicious activity to a workload based on a forensic log. The method includes detecting in at least one cloud log of a cloud computing environment a plurality of events, each event indicating an action in the cloud computing environment; extracting from an event of the plurality of events an identifier of a cloud entity, wherein the event includes an action which is predetermined as indicative of a suspicious event; traversing a security graph to detect a node representing the cloud entity, wherein the security graph further includes a representation of the cloud computing environment; detecting that the node representing the cloud entity is connected to a node representing a cybersecurity vulnerability; and initiating a mitigation action for the cloud entity based on the cybersecurity vulnerability.
