Securing IP PBX against attacks and resistance testing
Kakvic, Martin ; Šedý, Jakub (referee) ; Šilhavý, Pavel (advisor)
This diploma thesis focuses on attacks on PBX Asterisk, FreeSWITCH and Yate in LTS versions. In this work was carried out two types of attacks, including an attack DoS and the attack Teardown. These attacks were carried out using two different protocols, SIP and IAX. During the denial of service attack was monitored CPU usage and detected if its possible to establish call and whether if call can be processed. The Security of PBX was build on two levels. As a first level of security there was used linux based firewall netfilter. The second level of security was ensured with protocols TLS and SRTP.

Best Practices pro xUnit testování
Matoušek, Lukáš ; Pavlíčková, Jarmila (advisor) ; Šlajchrt, Zbyněk (referee)
The main goal of this work is to explain to the students the practices of unit testing. In this work are many English words that cannot or have not yet been translated. The theoretical part at the beginning discusses what is software testing, and then notifies you to several methods of testing during the development of the software. Explain the basic concepts such as the software error, verification, validation, quality and reliability testing. After a short introduction into testing the work is going down deeper into the practices of the JUnit testing. Goes through each component part of unit testing that after the merger are key practices to create a unit test. The output of this part is a little guide to writing unit tests. Bachelor thesis should be used as a study material for students of introductory courses of programming 4IT101 - Introduction to Programming and 4IT115 - Fundamentals of Software Engineering at the University of Economics, Prague. The practical part deals with by creating extensions to the IDE BlueJ, which serves as a simple check of unit tests for the students. Students may use this extension when carrying out school projects in courses 4IT101a 4IT115.
