Abstract
A method includes accessing, by a hypervisor executing by a processing device, a filtering queue that stores at least one packet determined to be malicious by a virtual machine, generating, by the hypervisor, a filtering rule in view of characteristics of the at least one packet determined to be malicious, and storing the filtering rule in a data store to apply to subsequent packets addressed to the virtual machine to determine whether any of the subsequent packets have similar characteristics with the at least one packet determined to be malicious.
