In order to increase the protection ability of the network intrusion diction system (NIDS), it is important to gather the host information of the intruder. In the proposed IDS called NIDS-SA, three basic components are developed to support the active monitoring capability, Intrusion Detection Node (IDN), Intrusion Detection Coordinator (IDC), and Snooper Agent (SA). The IDN is used to capture packets,...
Current popular sampling algorithms canpsilat provide accurate approximation of true character under the circumstance of network traffic bursting. In the paper, we develop an adaptive network traffic sampling methodology (MANFC-AT) based on aggregated time-serial evolution trend. The MANFC-AT algorithm adaptively adjusts the time interval between consecutive samples according to the evolution trend...
Analyzing the characteristic of network behavior provides scientific basis for designing, building, and managing the next generation Internet, and is especially important for monitoring network behavior. This paper establishes a system of metrics that evaluates the behavior of IP networks with respect to the need of analyzing network behavior, introduces the design and implementation of network monitoring...
