Security Analysis of Smart Home Devices
Grofčík, Peter ; Kmeť, Martin (referee) ; Matoušek, Petr (advisor)
Main purpose of my bachelor thesis is to analyze security of smart home devices and afterwards to test and confirm exposed vulnerabilities on these devices. The first section describes MioSMART kit devices used for analysis including ways, how to access them. The next section describes communication of smart home devices including protocols, that are used for it. In the next chapter, free tools are introduced to identify vulnerabilities in IoT communications. The next section contains description of network attacks that were carried, based on detected vulnerabilities to damage the functionality of smart home devices. Part of this chapter is dedicated to the description of monitoring options for ongoing attacks on smart home devices.

Configuring Linux Mail Server
Babický, Karel ; Pícka, Marek (advisor) ; Mikoláš, Mikoláš (referee)
The aim was to configure a Linux mail server, which should serve as a complement to web hosting, therefore should be able to serve multiple domains at once. The next task was to test the server base.
The theoretical part explained how email works, describes the steps that occur from sending to receiving message. They described the various components of the mail server. Furthermore the most important protocols have been described, what purpose they have, how they work and at which ports they operate.
In the practical part was at first selected a suitable solution mail server. Postfix server and additional necessary components were chosen eventually. Dovecot was installed to manage mailboxes and IMAP implementation. ClamAV antivirus and antispam BitDefender were installed as protection. Step-by-step changes in the setting were described. The solution has been tested for security.
