Malware Filtering is a project of Deutsche Telekom Laboratories supported by DAI-Labor. Here, on the one hand the tool NeSSi (Network Security Simulator), an evaluation environment for network security measures is build. Second, new detection algorithms enabling the detection of e-threats like malware such as worms, viruses and spam, are realized.

NeSSi allows the simulation of large, real-life IP networks and its inherent properties. In this respect, special attention was devoted to the faithful emulation of the TCP/IP protocol stack. JIAC TNG agents are employed to represent the network components of the simulation environment for efficient simulation.

Beside the pure network simulation, NeSSi offers the economical assessment of a security infrastructure set-up in a network. A security
configuration can be associated with costs and by running several attack scenarios like worm propagation, virus spread or DDoS an achieved security level can be compared to the preceding investments.

In addition, NeSSi offers an open API for the plug-in of detection algorithms. This can either be conventional approaches like a virus scanner or customized as well as scientific approaches.

The second track of the project is the development of such approaches.  Accordingly, there are algorithms based on biological-inspired techniques as well as on collaboration schemes. Finally, by means of network analysis, dedicated locations for the deployment of detection algorithms are exposed.
