An intrusion detection model for satellite network

The current intrusion detection technology based on the ground network is not adapted in the satellite network because of its motion. Analyzing the function characteristic of the satellite nodes, this paper builds a security domain based on the login and log-out mechanism, then a lamination distributed intrusion detection model of satellite network is proposed and a cooperation mechanism of intrusion detecting agent on satellite working inside and between the security domains is designed. The result of simulation proves that the intrusion detection model and cooperation mechanism are adapted in the satellites network.
