Abstract

Some embodiments provide a method for identifying security threats to a datacenter. From multiple host computers in the datacenter, the method receives attribute sets for multiple flows. Each respective attribute set for a respective flow includes at least (i) a source identifier for the respective flow and (ii) an indicator as to whether the respective flow is indicative of the source of the respective flow being a security threat. For each of multiple source identifiers, the method aggregates the received attribute sets to generate an aggregate attribute set for the source identifier that includes a combined measurement of security threat indicators. For a particular source identifier, the method adjusts a security threat likelihood score for the source corresponding to the particular source identifier based on the combined measurement of security threat indicators for the source identifier.
