A Topology-Adapted Network Defense Model Based on Mobile Agent

摘要

Since the topology of now network system is always dynamic, the paper provides a network active defense model that is adaptive for dynamic topology based on the mobile agent technology. The model includes three parts: network topology discovery, adaptive agents modulation mechanism and active defense. The model provided by the paper contains two kinds of agents: topology discovery agent and defense one. The model uses mobile network topology discovery agents to actively probe the current network topology and encodes it; then the adaptive modulation part of the model implements the distribution and migration of the defense agents according to the current topology; at last the defense agents then make active defense for the network.
