System Log Analysis
Ščotka, Jan ; Peringer, Petr (referee) ; Smrčka, Aleš (advisor)
The goal of this master thesis is to make possible to perform system log analysis in more general way than well-known host-based instrusion detection systems (HIDS). The way how to achieve this goal is via proposed user-friendly regular expressions. This thesis deals with making regular expressions possible to use in the field of log analysis, and mainly by users unfamiliar with formal aspects of computer science.
Attack Detection by Analysis of the System's Logs
Holub, Ondřej ; Puš, Viktor (referee) ; Kaštil, Jan (advisor)
The thesis deals with the attack detection possibilities and the nonstandard behaviour. It focuses on problems with the IDS detection systems, the subsequent classification and methods which are being used for the attack detection. One part of the thesis presents the existing IDS systems and their properties which are necessary for the successful attack detection. Other parts describe methods to obtain information from the operating systems Microsoft Windows and it also analyses the theoretical methods of data abnormalities. The practical part focuses on the design and implementation of the HIDS application. The final application and its detection abilities are tested at the end of the practical part with the help of some model situations. In the conclusion, the thesis sums up the gained information and shows a possible way of the future development.
