APPLICATION OF NETWORK LOAD ANALYSIS SYSTEM FOR DETECTING START OF DDOS ATTACK
Different web resources including state and geoinformational systems can be exposed to denial of service (DDoS) attacks. The goal of this investigation is determining the efficiency of developed system for network load analysis. Problem of DDoS-attacks is considered together with existing methods and measures for counteraction of such kinds of attacks. An approach to determining attack beginning is examined in details. Developed system, its architecture and functionality of each module are described. Testing results are given for both normal traffic conditions and abruptly increasing load, which models avalanche DDoS-attack. The system builds graphs to visualize monitoring process which definitely show attack beginning. A conclusion is made that the system can be used for DDoS-attack detection.
