Network-Based Application Recognition
Štourač, Jan ; Barabas, Maroš (referee) ; Malinka, Kamil (advisor)
This thesis introduces readers various methods that are currently used for detection of network-based applications. Further part deals with selection of appropriate detection method and implementation of proof-of-concept script, including testing its reliability and accuracy. Chosen detection algorithm is based on statistics data from network flows of tested network communication. Due to its final solution does not depend on whether communication is encrypted or not. Next part contains several possible variants of how to integrate proposed solution in the current architecture of the existing product Kernun UTM --- which is firewall produced by Trusted Network Solutions a.s. company. Most suitable variant is chosen and described furthermore in more details. Finally there is also mentioned plan for further developement and possible ways how to improve final solution.

Network Capacity Optimization on UNIX

Title: Optimizing the utilization of networks' capacity on unix-like systems Author: Martin Pelikán Department: Department of Distributed and Dependable Systems Supervisor: RNDr. Leo Galamboš, Ph. D., Department of Distributed and De- pendable Systems Abstract: Modern unix-like systems contain very powerful network stacks with configuration options often beyond operators' understanding. A comparison of available algorithms, documentation and visualization of certain components help their understanding, leading to better configuration choices. By explaining the network stack from the drivers up to the network layer will exhibit problems with timekeeping, burst traffic processing or queue management with regard to classification, scheduling or traffic regulation options in Linux or OpenBSD. The thesis works as an overview of implemented algorithms and updated documen- tation of Linux's actions and filters, while the implementation introduces a new portable tool to visualize existing configuration on remote machines without the need of modifying them. Keywords: network internals, traffic shaping, traffic classification, queue ma- nagement 1
