Systems and methods for adjusting suspiciousness scores in event-correlation graphs

摘要

A computer-implemented method for adjusting suspiciousness scores in event-correlation graphs may include (1) detecting a suspicious event involving a first actor and a second actor within a computing system, (2) constructing an event-correlation graph that includes (i) a representation of the first actor, (ii) a representation of the suspicious event, and (iii) a representation of the second actor, and (3) adjusting a suspiciousness score associated with at least one representation in the event-correlation graph based at least in part on a suspiciousness score associated with at least one other representation in the event-correlation graph such that the adjusted suspiciousness score associated with the at least one representation is influenced by the suspicious event. Various other methods, systems, and computer-readable media are also disclosed.
