Denial of Service detection methods
Horský, Milan ; Zeman, Václav (referee) ; Sikora, Marek (advisor)
This bachelor thesis deals with a methodology for detecting and describing the Denial of Service (DoS) condition on a web server. The aim of the thesis is to develop and implement methods that enable effective detection of DoS attacks in an experimental network. The theoretical part focuses on the analysis of different types of DoS attacks, including their detection on the application server and network side, and discusses possible reasons for false positives. In the practical part, software tools for monitoring and analyzing server and network resources were developed and then tested against different types of DoS attacks. As a result of the work, the proposed methodology has been validated and implemented in an experimental network, which provides useful tools for improving the security and stability of web servers.

Hardware acceleration of packet classification using TC Flower
Benc, Marek ; Fujcik, Lukáš (referee) ; Libich, Jiří (advisor)
Sdružení CESNET vyvíjí vysokorychlostní programovatelné síťové karty COMBO (aktuálně až s dvěma 100Gbps porty) zaměřené na analýzu a zpracování síťových dat. Karty obsahují FPGA čip, který dovoluje uživatelům přesně definovat způsob, jakým má být síťový provoz zpracován. Jedno z možných využití těchto karet je jako síťový přepínač pro virtuální stroje v data centru. Tato práce je zaměřená na implementaci podpory TC Flower offloadu pro karty COMBO (software a FPGA firmware). Jedná se o všeobecné rozhraní pro instalaci flow pravidel typu shoda+akce do SmartNICů, a dovoluje nám použít je pro správu síťového provozu mezi virtuálními stroji a vnějším světem. Cílem je úspora procesorových cyklů hostitelského stroje.

Automated system for installing and configuring GNU/Linux virtual hosts
Horák, Daniel ; Polívka, Michal (referee) ; Pelka, Tomáš (advisor)
This work deals with possibilities of administration of virtual machines (mainly from the developer's point of view) and available methods for automatic installation of GNU/Linux distributions. First part contains the information about virtualisation technologies and possibilities to configure them with a libvirt library. The definition and specification of each part of virtualisation environment (virtual machines, disks, networks) using XML is described. Further more the possibilities of automatic installation of Linux distributions based on RedHat and Debian considering the virtualisation environment are discussed. The possibility of copying an existing disk with installed system is also mentioned. In a practical part a server application for control and management of virtual machines including automatic installation of operating system is proposed and realised.
