In this paper an algorithm for detecting anomalous behavior on computer systems is proposed. The work is based on information from the behavior of authorized users who have performed various tasks on a computer system over two years. The study uses a dynamic data structure that can encode the current activities of users and their behaviors. The identification of the most and least frequent tasks,...
Classification techniques based on Artificial Intelligence are computational tools that have been applied to detection of intrusions (IDS) with encouraging results. They are able to solve problems related to information security in an efficient way. The intrusion detection implies the use of huge amount of information. For this reason heuristic methodologies have been proposed. In this paper, decision...
