Resumen de Intrusion-detection systems: guaranteing the safety of a network beyond using a firewall
The increase in the number of links with the Internet has generated a proportional increase in the number of attacks brought against them. Implementing systems capable of detecting these attacks (possibly without false alarms, which in some cases is an imposible dream), and also giving the system administrator the oportunity to intervene inmediately, is an specific area of the networking reseach: intrusion detection. This article discusses how and why intrusion-detection systems (IDss) should be used to record and report possible violations of information systems linked to the Internet.
