Abstract
A system and method for detecting aberrant network behavior. One embodiment provides a system of detecting aberrant network behavior behind a network access gateway comprising a processor, a first network interface coupled to the processor, a second network interface coupled to the processor, a storage media accessible by the processor and a set of computer instructions executable by the processor. The computer instructions can be executable to observe network communications arriving at the first network interface from multiple clients and determine when the traffic of a particular client is indicative of malware infection or other hostile network activity. If the suspicious network communication is determined to be of a sufficient volume, type, or duration the computer instructions can be executable to log such activity to storage media, or to notify an administrative entity via either the first network interface or second network interface, or to make the computer instructions be executable to perform other configured actions related to the functioning of the network access gateway.
