For many years, the security has become a main issue in Internet community. Intrusion detection systems (IDSes) are security tools which should indicate when someone is breaking into a system. However, as this thesis shows, the local exploits are not well detected and IDSes generate a huge amount of data that should not always be considered as intrusion. There is no universal IDS, all IDSes have different strengths and weaknesses. The detection of intrusion can be improved by correlating different information sources and by considering the environment in which they occur.
