The systems and methods described herein include adaptive routing processes for packet-based wireless communication networks. This routing approach works both in MANETs (when a contemporaneous end-to-end path is available) and in DTNs (when a contemporaneous end to end path is not available, but one of formed over space and time). In particular, the methods include adaptively selecting a routing process for transmitting a packet through a node in the network based on available information on the network topology and/or the contents of the packet.

Systems and methods for adaptive routing in mobile ad-hoc networks and disruption tolerant networks

A method of determining correlated flows in a network may include obtaining times of arrival and corresponding flows for data units in the network () and assigning weights to a set of data units based on respective times between the set of data units and one data unit (). A probability matrix representing interflow connections in the network may be updated based on the assigned weights ().

Method and system for detecting attack path connections in a computer network using state-space correlation

A method and system is provided for detecting correlated connections in an extended connection. A plurality of stepping stone detection algorithms are executed in parallel (), each of the plurality of stepping stone detection algorithms generating a result. The results are scored for each of the plurality of stepping stone detection algorithms (). A consensus attack path is generated based upon the scored results ().

Method and system for aggregating algorithms for detecting linked interactive network connections

A system and method for determining the point of entry of a malicious packet into a network is disclosed. An intrusion detection system detects entry of the malicious packet into the network (). A stepping stone detection system identifies stepping stones in extended connections within the network (). A traceback engine isolates the malicious packet in response to operation of the intrusion detection system (), wherein the traceback engine utilizes the identified stepping stones to determine the point of entry of the malicious packet.
