A method and system for providing network based malware detection in a service provider network is disclosed. Transmission control protocol (TCP) packets defining originating from an access device coupled to the service provider network defining a TCP session between a computing device coupled to the access device, and a destination coupled to the service provider network are received. An operating system identifier (OS ID) associated with the TCP session and the computing device is determined. If malware is present in the TCP session and an associated malware ID is determined by comparing a malware signature to the one or more TCP packets. An alert identifying a network address associated with the access device, the malware ID and the OS ID associated with TCP session that generated the alert can then be generated.

Method and system for operating system identification in a network based security monitoring solution

A method and apparatus are provided for identifying and tracking multiple computer user sessions associated with a network address translation (NAT) device coupled to a computer network. Data packets originating from the NAT device containing a request to a destination server coupled to the computer network are received. A client source address associated with the data packets is determined where the source address associated with the NAT device. One or more session entries associated with the client source address can then be determined, wherein the session entries are stored in system state information. A session signature can then be determined based one or more characteristics defined by the data packet header information and/or request header information in the one or more data packets, the session signature uniquely identifying one of the multiple computer user sessions coupled to the NAT device.
