  1. Modeling and simulation at the service of cyber security Vahur Kotkas IoC, dept. of Computer Science

  2. Security issues • Availability • Privacy • Integrity • Maintainability

  3. How to defend ourselves • Be prepared (planning and built-up): • carry out analysis, • deploy reasonable equipment • purchase special equipment and prepare tools for • intrusion detection, • data-mining, • blacklist management and exchange, • filtering, • Logging • configure the equipment properly • reserve some resources for any case, • Have trained staff (education)

  4. What kindof activities are needed? • Educational simulations • Protocols, routing algorithms, configurations, ... • Network deployment planning • Topology, equipment, configuration • Usage optimization • Resource consumption analysis • Hardware, services • Attack simulations • Malware spread simulation • Service availability simulations • Do it all on top of a realistic model of Estonian Internet

  5. Different levels of activities • High-level management • Mid-level technical solutions • Low-level real life

  6. What is available? • Number of existing tools for network simulations: • OPNET, OMNeT++, NS, Netscale, Netwiser, J-Sim, PARSEC, QualNet, SSF, ... • Number of model (network topology) generators • BRITE, Inet, Topgen, ReaSE, ...

  7. What we do? • Modeling and simulation platform – CoCoViLa (http://www.cs.ioc.ee/cocovila) • High-level behaviour descriptions • Hierarchical visual composition • Expert-systems • Combined simulators • Discrete event based simulation • Continuous-time simulation • Visualisation

  8. Tools for different activity levels - DEMO • Situation Analysis by Jüri Kivimaa et al. • Attack Trees by number of people including Ahto Buldas, Aivo Jürgenson, Jan Willemson etc. • HNS (Hybrid Network Simulator) by Andres Ojamaa • GrADAR (Graph-based Automated Denial-of-Service Attack Response) by Gabriel Klein et al. • EIM (Model of Estoian Internet) by Andres Ojamaa et al.
