Module for Network Policy Monitoring in Flow Data
Piecek, Adam ; Kučera, Jan (referee) ; Wrona, Jan (advisor)
The aim of this master's thesis is to design a language through which it would be possible to monitor a stream of network flows in order to detect network policy violations in the local network. An analysis of the languages used in the data stream management systems and an analysis of tasks submitted by the potential administrator were both carried out. The analysis specified resulted in the language design which represents pipelining consisting of filtering and aggregation. These operations can be clearly defined and managed within security rules. The result of this thesis also results in the Policer modul being integrated in the NEMEA system, which is able to apply the main commands of the proposed language. Finally, the module meets the requirements of the specified tasks and may be used for further development in the area of monitoring network policies.

A Tool for Testing Network Applications
Hornický, Pavol ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
This master thesis addresses the issue of software testing. It discusses different types and forms of testing such as white-box testing, black-box testing, unit testing, integration testing and regression testing. Further it deals with the specific problems of testing network applications and automation of the testing process. To solve these issues, the thesis presents a language based on XML for describing testing cases. The following chapter describes the design of this language interpreter. The thesis also deals with problems occurring during implementation phase of similar tools and their possible solutions. Functionality demonstration of designed tool helped to discover an error in product of AVG Technologies CZ, s.r.o..
