Network Protocol Analyzer
Hlísta, Juraj ; Žádník, Martin (referee) ; Tobola, Jiří (advisor)
Bachelor's thesis is concerned with methods of protocol detection at seventh layer of ISO/OSI network model. It focuses on proposal and implementation of a system which is able to identify aplication protocols from packet's data field. This part of packet contains signatures that the analyzer searches for using regular expressions. The application was written in C programming language using libpcap library that provides API for capturing network communication.

Reactive Audit
Hlísta, Juraj ; Drozd, Michal (referee) ; Hanáček, Petr (advisor)
The thesis deals with the proposal and the implementation of an extension for the audit system in Linux - the reactive audit. It brings a new functionality to the auditing in form of triggering reactions to certain audit events. The reactive audit is implemented within an audit plugin and its use is optional. Additionally, there is another plugin which stores some audit events and provides time-related statistics for the first plugin. As the result, the mechanism of the reactive audit does not only react to some audit events, it is also able to reveal anomalies according to the statistical information and set ofe the appropriate reactions. It is a fairly general mechanism that can be useful in various situations.
