Network intrusion detection systems (NIDS) can be evaded by carefully crafted packets that exploit implementation-level discrepancies between how they are processed on the NIDS and at the endhosts. These discrepancies arise due to the plethora of ...

Signature-based network intrusion detection systems (NIDSs), such as Snort and Bro, rely on a rule database that describes traffic patterns for known attacks. They examine each packets flowing through a network segment and report suspicious packets to ...

Intrusion Detection System (IDS) is a software or hardware tool that repeatedly scans and monitors events that took place in a computer or a network. A set of rules are used by Signature based Network Intrusion Detection Systems (NIDS) to detect hostile ...
