Data Backup and Data Storrages
Bartošek, Lukáš ; Hynek, Luboš (referee) ; Kříž, Jiří (advisor)
The chosen theme of the thesis is data backup and data storage. They analyzed the situation, the problems related to data backup and data storage in a controlled marketing company. The following are the actual implementation of hardware for improving the current situation in the company. More content part of the theoretical bases of which are set out proposals for the issue.

Securing IP PBX against attacks
Hynek, Luboš ; Krajsa, Ondřej (referee) ; Šilhavý, Pavel (advisor)
This master project focuses on the possibilities of protecting the most common free software PBX Asterisk, FreeSWITCH and YATE. In practice, it was verified the behavior of PBX in the attacks and suggested protection against them on one of the most popular distributions of Linux server on CentOS. Tool was created to simulate several types of attacks targeting denial of service. Both protective options PBX themselves and operating system capabilities are used in this work. Comparison was also the possibility of protection of individual PBX with each other. It also includes a brief description of the protocol, topology attacks and recommendation for the operation of softswitches.

Open source PBX FreeSWITCH
Hynek, Luboš ; Daněček, Vít (referee) ; Šilhavý, Pavel (advisor)
This bachelor thesis focuses on the possibilities of using alternative soft-switch FreeSWITCH. It is verified the possibilities and difficulties of the installation (including expansion cards) onto the most popular Linux distribution, Ubuntu, in practice. The installation is described in such a way that we can get a functional PBX with secure communication using the SIP protocol, the routing of the analog phone and the primary circuit E1, if the procedure is followed. Emphasis is placed on communication security against eavesdropping on the route. It also contains a comparison of their options with the most Asterisk PBX software. It also includes a brief history and division of telephone exchange and transmission systems into generations. Finally there are two laboratory tasks designed to focus on the configuration of the SIP protocol PBX and the use of secure protocols during communication.
