Static methods for detection DDoS attacks

This thesis contains a theoretical basic for solution to issue of network anomalies with use of static methods and it also contains software as a solution for detection of network attacks. The main point of thesis is detection of DoS (Denial of Service) attacks. In thesis is located an analysis of DoS attacks rate categorization. Further in thesis is located analysis of protocols TCP (Transmission Control Protocol) and UDP (User Datagram Protocol), their possible use to attacks SYN flood and UDP flood. Here are analysed three static methods and their detailed description. There is also a analysis of collected data and their comparison in the thesis. Thesis contains description and the results testing of software which is used to detect attacks in network, at the end
