IMAP Proxy for POP3 Mailboxes
Kružliak, Miroslav ; Burget, Radek (referee) ; Kolář, Dušan (advisor)
This bachelor's thesis deals with retrieving e-mails from different accounts on POP3 servers and their organisation in one account on IMAP server. It also studies settings and configuration of IMAP servers in enviroment of operating system Linux. Protocols IMAP and POP3 are briefly compared here from implementation point of view. Further it studies possibilities of periodical start of processes and secure saving of sensitive information. In this part of my thesis main methods of cryptography are shortly confronted.

Data Acquisition from HTML Sites
Komenda, Tomáš ; Šimek, Václav (referee) ; Straka, Martin (advisor)
This work describes scope of creating application for extraction and following data from HTML sites. This work engages in lexical analyze and parsing HTML. This work describes filtration of data from HTML sites. This work describes saving of data in database and XML documents, creating of dynamic HTMP pages, timer cron, GNU utility wget, sending of SMS, sending email and extraction of date from internet. Final chapters describe two web applications. These applications follow data from HTML sites and inform users about changes.

Location visualization of sensor units
Hulanský, Jozef ; Verner, Lukáš (referee) ; Komosný, Dan (advisor)
This master thesis deals with wireless sensor network with protocol IPv6. In the begining there are explained the priciples of communication in wireless sensor network, and based on this teories are configured a wireles network with predefined development kit. Furthermore, by using geographic coordinates, positions of the nodes are displayed on a website, what is a part of this thesis. On this website are also presented the measured values from sensors. For saving all informations and measured values about each nodes was used remote MySQL server. Communication between this server and 6LoWPAN network provide Perl script which is runs at periodical intervals. With this method automatization of the whole system are ensured.

Weather Forecast Based on Different Sources
Hořák, Martin ; Kořenek, Jan (referee) ; Novotný, Tomáš (advisor)
Bachelor thesis deals with the weather forecast through the artificial neural network with backpropagation method. The forecast is based on data obtained from freely accessible services offering weather information. The created application downloads and saves the forecasts from servers and creates a new forecast. The results of the prediction are being compared with the reality and the original services.

Web Portal for Network and Application Response Time Monitoring
Hornický, Pavol ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
This bachelor's thesis describes the design and implementation of system for the response time monitoring of network services. This thesis describes the basic techniques used for such monitoring, and describes in detail the active monitoring. The core of the resulting system is the automated responses measurement of network services using standard UNIX programs. The web interface gives a clear view of captured responses using rrdtool graphs. The web interface is also used for monitoring management.

IT/OT modular honeypot
Nečas, Martin ; Fujdiak, Radek (referee) ; Blažek, Petr (advisor)
V bakalářské práci byl realizován modulární a škálovatelný systém honeypotů zaměřený na IT a OT. Cílem bylo navrhnout a implementovat systém, který umožní snadné přidávání modulů reprezentujících komunikační protokoly a virtuální zařízení a silně zdůrazňuje modularitu. Honeypoty jsou nasazeny v kontejnerech a systém aktivně monitoruje komunikaci mezi těmito kontejnery a útočníky. Všechny komunikační aktivity jsou uloženy v centralizovaném logu pro důkladnou analýzu a monitorování.
