We present a prototype of an Intrusion Warning System for combining event message flows of multiple domain-specific security tools in order to determine anomalies for early warning and response. Unlike other approaches for cooperating Intrusion Detection Systems (IDS), we suggest a modified star shape architecture for distributing attack information and(More)
This work investigates the amount of information about failures required to simulate a synchronous distributed system by an asynchronous distributed system prone to crash-recovery failures. A failure detection sequencer Σ CR for the crash-recovery failure model is defined, which outputs information about crashes and recoveries and about the state of the(More)
