Analysis and Design of Information System MEDIMED
Lebeda, Martin ; Malinka,, Kamil (referee) ; Neuwirth, Bernard (advisor)
This work deals with the modifications of project MeDiMed, which ceased to meet the requirements it imposed. In the first part the main objectives, targets and methods to achieve them are defined. The second part deals with the theory that is needed to understand the issue. In the practical part, which is based on the theory is prepared SWOT analysis and the modified HOS-8 analysis of the current state, whose results are then analyzed. The next section presents design of new solution. The conclusion summarizes all the proposed solutions and knowledge that have been achieved in this work.

ISP Network Management
Svoboda, Filip ; Pavláček, Martin (referee) ; Ondrák, Viktor (advisor)
The subject of this thesis is management of computer network managed by internet service provider in the village Boleradice. Based on the analysis of current management practices weakness in monitoring was revealed. In order to address this issue a server was purchased, on which was installed Nagios, an advanced monitoring tool. The benefit of this project is increased efficiency and improved management of the network and ability to quickly respond to outages of network devices.

Monitoring the operation of local internet networks
Papež, Nikola ; Bartl, Milan (referee) ; Verner, Lukáš (advisor)
This thesis deals with issues of traffic monitoring of local internet networks. Attention is paid to describing main functions and methods of network monitoring, consequently standards for monitoring such as SNMP protocol, WMI service or Cisco NetFlow methods. There are also described some other basic tools with open source licence used for monitoring. The main contribution of this thesis is clarification and subsequent usage of these methods for monitoring on VUT network. For this intermediation was used Nagios tool which used Nagios tool which provided feedback about the status of devices together with the own programmed plugin and tool Cacti which collected data from these devices and created graphical dependencies.

Comparison of Systems for Monitoring of Computer Networks
Vozdecký, Lukáš ; Kašpárek, Tomáš (referee) ; Čejka, Rudolf (advisor)
This thesis is comparison of three open--source Linux/Unix network monitoring applications Nagios, Zabbix, Big Sister. Every application is described according to its basic fundamentals. The comparison is done through managing series of tests based on real environment experience. Solution to these problems and specific procedure differencies are described for each application.

Implementation of open source system for network monitoring
Scripnic, Dmitrii ; Sládok, Ondřej (referee) ; Grenar, David (advisor)
The bachelor thesis deals with network monitoring. In this work, a theoretical analysis of known monitoring systems was performed and their architecture, properties and work with these systems were also described. Subsequently, a comparative characteristic of all described systems was performed. At the beginning of the practical part, the installation and configuration of all monitoring systems and their evaluation was performed. The second part deals with the Zabbix monitoring system, where more emphasis was placed on monitoring IP service delays.

Design and Implementation of the Surveillance Information System
Čelka, Marek ; Jiřík, Leoš (referee) ; Luhan, Jan (advisor)
The main goal of the master thesis is design and implementation of information system for monitoring purposes. The implemented monitoring system will be able to automatically monitor devices of a certain company. This goal is preceded by strategic analysis using PEST and 7S methods for examination of current state of the company. Another part is the analysis of the efficiency of service processes using the HOS method together with the selection of a suitable monitoring system. An enhancement of service processes is designed by the Lewin model. Finally, the selected information system for monitoring was designed, implemented and tested. A deployment of the system should provide simplification of devices supervision, to save costs as well as to speed-up the response-time to unexpected situations.

Identification of Device Availability in Technological Networks
Vodehnal, Stanislav ; Mlýnek, Petr (referee) ; Škorpil, Vladislav (advisor)
This diploma thesis deals with the monitoring of network elements of technological networks and distribution systems. There are described reasons why and what kind of values we want to monitor. Three monitoring systems are then selected, described their properties and functions. Based on their merits, one system for deploying the test environment is selected. The practical part is the configuration of the selected system and its subsequent deployment to the network.

Enterprise Network Design and Simulation - Cisco Virtual Lab
Ollé, Karol ; Komosný, Dan (referee) ; Soumar, Michal (advisor)
Tématem této diplomové práce (dále jen DP) je návrh rozsáhlých podnikových sítí podle doporučení stanovených společností Cisco. Dále je realizována simulace navržené topologie prostřednictvím programů s otevřeným zdrojovým kódem a dohled nad sítí prostřednictvím programu Nagios. Úvodní část obsahuje stručné seznámení se základním rozdělením sítě do jednotlivých funkčních bloků. Druhá část se zabývá popisem jednotlivých funkčních bloků a jejich rolí v rámci celé síťové topologie. Bloky jsou dále rozděleny na jednotlivá zařízení a jsou popsány služby, které tato zařízení musí poskytovat. Třetí část DP se snaží zmapovat základní požadavky na služby, které jsou kladeny na dnešní síťové infrastruktury. Hlavní důraz je kladen na dostupnost všech nabízených služeb sítě. Jsou vyjmenovány jednotlivé protokoly druhé až třetí vrstvy OSI modelu, které zabezpečují stálou dostupnost sítě v případě selhání aktivních prvků. Čtvrtá část DP se věnuje popisu návrhu síťové topologie WAN. Pátá část obsahuje popis bezpečnostních rizik, která ohrožují dostupnost sítě, tak i popis útoků, které mají za cíl krádež identity uživatele. V šesté části DP jsou popsány programové nástroje pro zprávu sítí (Nagios, Cisco Security Device Manager) a programy, které simulují Cisco přepínače, směrovače (Dynamips & Dynagen, GNS3) a Cisco PIX firewall (PEMU). Sedmá kapitola se zabývá konkrétním návrhem rozsáhlé sítě s použitím principů, které byly zmíněny v předcházejících kapitolách. Navržená infrastruktura je dále realizována pomocí simulačních programů a tato virtuální síť dovoluje demonstrovat nastavení a chování všech popsaných protokolů a zařízení. V závěrečném shrnutí je nejdůležitější poznatek, že návrh a konfigurace rozsáhlé sítě a její realizace ve virtuálním prostředí je funkční a použitelná pro pokusné účely i pro studijní účely.
