System for Guarding and Securing Objects and Areas
Kuchařík, David ; Kubek, Ján (referee) ; Strnadel, Josef (advisor)
This project deals with given safeguard possibilities, both mechanical and electronic. A row house with garden was chosen for being secured. Subsequently, were elaborated two`s proposals of securing and guarding of this object. First, was based on camera`s system and second on common system ESS. Later on they were evaluated and the most considerable benefits were emphasized. A system based on control panel with connected detectors was selected upon specification. Subsequently was created a model of the chosen system, at which the required behaviour was simulated and verified. An outline of an implementation was created in the C language.

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.

System for Guarding and Securing of Objects and Areas Based on Arduino Platform
Juríček, Jakub ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
This bachelor`s thesis deals with the analysis, design and implementation of a system, that can be used to secure objects, in order to detect and report a potential threat. Emphasis is placed on the ability to control and configure the system and on its easy adaptability to various objects. Part of the thesis is focused on analysis of a fictitious object, on which the appropriate location of the sensors is shown. The design is carried out on the Arduino platform and with the use of various types of sensors and controls, a first-level functional alarm system is capable to monitor case, movement, fire or temperature disturbance and immediately report this fact both acoustically and visually. Configuration interface is used to set system properties. The solution is tested in a complex way on a particular object with a fixed number of sensors.

Wireless electronic security and surveilance system
Vichta, Michal ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
This bachelor thesis is engaged in proposal and implementation of wire less safeguarding system. The proposal is consisting from study of single components wire less safeguarding system like for example: detectors, central, GSM communicator and mobile station. The bechelor is engaged familiarization of technologies for formation sensing element networks and proposal (principal) diagram wire less systém of familly house. For realization wire less network is exploit standart IEEE 802.15.4 ZigBee on a frequence 2,4 GHz and radio outside on a work frequence 868,3MHz. Beside terminal arrangement and near co-ordinator is exploiting Zigbee program units from Meschnetics company too. Next to radio outsider is exploiting wire less base extension station from Satel company. Both of wire less are connected with a central of wire less safeguarding system and conseguently connected with GSM communicator from Satel company, whitch on is concernig abouth sendings of messages abouth loom of wire less safeguarding system towards to user on mobile station.

Management and configuration of Asterisk VoIP exchange
Binder, Tomáš ; Krajsa, Ondřej (referee) ; Číka, Petr (advisor)
This diploma dissertation is dealing with the VoIP software exchange Asterisk. In the dissertation there are described its abilities and possible ways of its configuration. Special attention is given to the signalling protocol SIP, which is described in one of the chapters. Within this dissertation a dial plan, which demonstrates the technique of dial plan creating, was created. Within the boundaries of the dialplan following services could be found: a voicemail, conference, Interactive Voice Response and call queues. Configuration files, with the help of which the exchange is configurated, are described in my dissertation as well. Finally, three laboratory assignments for purposes of the subject Multimedia Services are mentioned. Their main aim is to familiarise students with the creation of SIP accounts in the exchange, their mutual connections, defining the Interactive Voice Response and forming a new call centre.

Possibilities of connecting the Asterisk softswitch to the 4th generation PBX
Halamík, Zdeněk ; Krajsa, Ondřej (referee) ; Šilhavý, Pavel (advisor)
This master’s thesis dissertate the possibilities of the linkage between Asterisk softswitch and the 4th generation private branch exchange. This should create a new generation’s network, so-called NGN, by the convergence of existing telecommunication networks with an IP computer network. This master’s thesis is divided into several chapters. In introduction is described the evolution of the private branch exchanges as well as the principles of the voice digitizing, codecs and signaling commonly used in both TDM and VoIP networks. The main aim of this project is the configuration of Asterisk software exchange for connection with PBX Alcatel 4400 as well as public phone network PSTN. Another goal of this master’s thesis was the configuration of Alcatel PBX and diagnostics of CCS and CAS signaling on E1 interface. In conclusion there are summarized advantages of NGN networks and their utilization in the future.
