Anti DDoS systém postavený na open-source platformě

Abstract

This master‘s thesis deals with the design of an open-source system for the detection and reduction of network attacks, testing and verification of a created system within a school laboratory. In the theoretical section there is a description of various basic and network DoS/DDoS attacks. Other sections will explain the principles of DoS/DDoS defensive mechanisms and the tools used for DoS/DDoS attacks with a rating of actual situational effectiveness on the field. In my thesis you can also find the required steps for the successful use of the open-source program on Ubuntu 14.04. The actual testing, which was done in the school’s lab, completes a presentation of graph outputs from packet analyzers and also comments on the steps. The program was created to automate the reduction of network attacks and protection of devices and services. The whole code is placed at the end of the document as an appendix.
