Abstract

This bachelor's thesis deals with the development of new mitigation strategies that are designed to suppress DDoS attacks that exploit packet fragmentation. It analyses fragmented traffic primarily emphasizing the order of fragmented packets. Based on the result of the analysis, it implements a new heuristic method for port numbers inference. The work also measures the latency and throughput of newly implemented functionalities. All new methods are integrated in a project developed by the CESNET association.

Keywords
