Intrusion Detection Systems: Definition, Need and Challenges

ثبت نشده
چکیده

IDS are becoming the logical next step for many organizations after deploying firewall technology at the network perimeter. IDS can offer protection from external users and internal attackers, where traffic doesn't go past the firewall at all. However, the following points are very important to keep in mind. 1. Strong identification and authentication: An IDS uses very good signature analysis mechanisms but strong user identification and authentication mechanisms are still needed. 2. IDS are not a solution to all secur...

A Parallel Genetic Algorithm Based Method for Feature Subset Selection in Intrusion Detection Systems

Intrusion detection systems are designed to provide security in computer networks, so that if the attacker crosses other security devices, they can detect and prevent the attack process. One of the most essential challenges in designing these systems is the so called curse of dimensionality. Therefore, in order to obtain satisfactory performance in these systems we have to take advantage of app...
