Pavel Celeda, Jiri Novotny & Radek Krejci, Masaryk University BrnoThese days the problem of cyber security is of utmost importance. Massive cyber attacks targeting government and mission critical servers can swiftly become an issue of national security. Various approaches for cyber defence and cyber security used to date have been based on software solutions without hardware acceleration. With the increasing number of network users, services and the current generation of multi-gigabit network links, the amount of transferred data has increased significantly. These facts have rendered many current solutions for network security obsolete. This presentation describes hardware-accelerated monitoring system. The time and performance critical parts are processed in hardware and only the relevant traffic parts are processed in software. Such approach allows us to use current security tools in multi-gigabit networks under worst-case scenarios like a distributed denial-of-service attacks. We present various deployment use cases for network security monitoring.Jiri Novotny graduated at Radio Communications from Technical University Brno in 1981. Since 1983 he has worked with the Institute of Computer Science at the Masaryk University Brno. He works on hardware development of new generation of PCI cards based on FPGA technology and leads the team developing high-speed network monitoring adapters – www.liberouter.org. He and his team participated on several network security related projects.
