Since it is essentially impossible to write large-scale software without errors, any intrusion tolerant system must be able to tolerate rapid, repeated unknown attacks without exhausting its redundancy. Our system provides continued application services to critical users while under attack with a goal of less than 25% degradation of productivity. Initial(More)
We have built a system for protecting Internet services to securely connected, known users. It implements a generate-and-test approach for on-line attack identification and uses similarity rules for generalization of attack signatures. We can immediately protect the system from many variants of previously unknown attacks without debilitating waits for(More)
