Um analisador de intrusões baseado em séries temporais

Abstract

In the same time that Internet grows and many services had converged, some algorithms – with objective to capture confidential information in the computers network – had evolved. Therefore, some methods became essential to deny the illegal access. While some methods were configured to interrupt malicious users, many intruders find ways to break the security of systems. The security is based on three things: confidentiality, integrity and disponibility, and many times the network managers forgot the last of this three. Because that, this work was focused to find disponibility attack attempts. To do that was established: the attacks; the characteristics of witch attack; how the attack could be detected using Temporal Series; and finally, the development of a software called DIBSeT – Temporal Series Based Intrusion Detector – that identify network attack attempts.
