DDoSSim - System for Visual Representation of the Selected Distributed Denial of Service Attacks

This paper describes the software system for visual representation of the selected direct and reflected distributed denial of service attacks on the internal and the network resources, which is entitled DDoSSim. The system was designed to enable users to observe the method of operation of typical DDoS attacks through a visual simulation. It is configurable and interactive, thus allowing different scenarios to be predefined, simulated, and also modified during the simulation. After configuration the system plays a scenario in a step by step animation manner, making it possible for users to follow the complete attack. DDoSSim can be used as a teaching aid at the courses covering topics from computer security and/or network security area or to improve the overall awareness about the DDoS attacks.
