Automatic Grouping of Regular Expressions
Stanek, Timotej ; Kořenek, Jan (referee) ; Kaštil, Jan (advisor)
This project is about security of computer networks using Intrusion Detection Systems. IDS contain rules for detection expressed with regular expressions, which are for detection represented by finite-state automata. The complexity of this detection with non-deterministic and deterministic finite-state automata is explained. This complexity can be reduced with help of regular expressions grouping. Grouping algorithm and approaches for speedup and improvement are introduced. One of the approches is Genetic algorithm, which can work real-time. Finally Random search algorithm for grouping of regular expressions is presented. Experiment results with these approches are shown and compared between each other.
IDS system SNORT
MAURIC, Jakub
This work deals with Intrusion Detection Systems. It divides them into categories and describes their functions. It describes examples of their using. It deals primary with IDS System Snort, content of them and with an example of their implementation into an existing system. This document will be used like a short compact manual which describes a necessary theory of Intrusion Detection Systems and possibilities of their practical using.
