A Parallel Model of Intrusion Tolerance System: RC Model
Jing Cui · Chinese Journal of Computers · 2004
Intrusion Tolerance System has become another essential technique to protect Internet servers against intrusion succeeding to the firewall and IDS. The article proposes a parallel model of intrusion tolerance system (ITS): RC model. This model classifies the effects of intrusions on system resources and controls when attacks happen. It divides the resources into 3 levels: measurable resource, information resource and attribute resource, and divides the control status into 2 levels: code level and active level. The 5 levels can characterize the system security state accurately from different views, though they are abstract. The article also describes how to analyze an ITS using RC model, and provides some recovery methods and instances of RC Model.
