PROPOSTA DE ATUALIZAÇÃO AUTOMÁTICA DOS SISTEMAS DE DETECÇÃO DE INTRUSÃO POR MEIO DE WEB SERVICES

Abstract

The security of computer networks is indispensable for its administrators. Intrusion Detection Systems (IDSs) can increase their security but is very important to update them constantly. This research work proposes a model for sharing information between Computer Security Incident Response Teams (CSIRTs) and IDSs, aiming the achievement of an automatic update of the IDSs response actions data base, based on restrictive short-term measures suggested in security alerts issued by CSIRTs. This model is based on Web services and Extensible Markup Language (XML) technologies. It is also presented a multiagent architecture based on information retrieval and filtering techniques, designed to automatically maintain the IDSs attacks signatures mechanism up-to-date.
