Abstract
A scalable cyber-security system, method and architecture for the identification of malware and malicious behavior in a computer network. Host flow, host port usage, host information and network data at the application, transport and network layers are aggregated from within the network and correlated to identify a network behavior such as the presence of malicious code.
Claims12
A method for analyzing network, transport and application protocols in a computer network to identify a predetermined network behavior comprising the steps of:
- monitoring and logging a port usage in a first host in a computer network,
- monitoring and logging a set of first host information,
- monitoring and logging a set of data activities in the network for a predetermined change in the first host information and in a first host data flow, and,
- generating an alert to a user based on a correlation between the logged port usage, the logged first host information and the logged first host data flow.
A device for analyzing network, transport and application protocols in a computer network to identify a predetermined activity comprising:
- a sensor platform comprising at least one sensor configured to collect and export a predetermined data structure from within the firewall of the network comprising aggregated data about a network host, flow and address block, and comprising a sensor control processor,
- a correlator server configured to support at least one sensor control processor,
- an optical I/O module,
- an SRAM processing module, and,
- a DRAM processing module.
The device of 8 wherein the TCP flow rectifier is configured to output TCP payload streams in interleaved blocks for multiple flows simultaneously.
