Distributed denial of service filtering based on Mikrotik network devices
Rajj, Jakub ; Martinásek, Zdeněk (referee) ; Gerlich, Tomáš (advisor)
The bachelor thesis is focused on the issue of denial of service attacks. These types of attacks are still up to date, but are currently being used in their distributed form. The theoretical part of the thesis describes the basic mechanisms of attacks and the division of attacks. Also there are described the most famous type of attacks. The theoretical part also includes a description of how to respond to these attacks. Four basick methods are described (prevention, detection, identification and response), as well as intrusion detection and prevention systems (IDPS). The practical part deals with connection of intrusion detection system and router, for detection and filtration on said router.

Comparison of SIP implementations used in Asterisk and Kamailio open source PBX's
Rajj, Jakub ; Krajsa, Ondřej (referee) ; Šilhavý, Pavel (advisor)
The diploma thesis deals with the comparison and testing of private branch exchanges Asterisk and Kamailo. It also deals with the comparison of stack SIP and PJSIP. At the beginning of the thesis, there is a theoretical part describing private branch exchanges, SIP protocol and PJSIP. In the next section, the tested PBXs Asterisk and Kamailio are described and there is comparison of it´s functions. The private branch exchanges are installed, configured and tests are performed using the Spirent Testcenter C1. The results of the tests were processed into graphs and at the end there is a discussion about the results.
