— Black Hole Attacks are a serious threat to communication in tactical MANETs. In this work we present TOGBAD a new centralised approach, using topology graphs to identify nodes attempting to create a black hole. We use well-established techniques to gain knowledge about the network topology and use this knowledge to perform plausibility checks of the(More)
Mobile ad hoc networks (MANETs) provide possibilities to realize IP-based networks without the presence of a fixed infrastructure. Therefore, this technology has also become attractive for tactical networks, such as in command posts, vehicle convoys, autonomous robot systems, and also for infantry troops. Due to its radio characteristics, it is widely known(More)
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)
Testing Intrusion Detection Systems (IDS) has been a substantial part of the development lifecycle, since the first prototypes and products appeared on the market. Unfortunately, many of the existing principles, procedures and systematic frameworks for testing IDS are not broad enough to cover systems which are focussed on mobile adhoc networks (MANETs). (More)
