- Characterizing Intrusion Tolerant Systems Using a State Transition Model
- Intrusion detection and response research has so far mostly concentrated on known and well-defined attacks. The authors believe that this narrow focus of attacks accounts for both the successes and limitation of commercial in Intrusion Detection Systems IDS. Intrusion tolerance, on the other hand, is inherently tied to functions and...
