A Parallel Architecture for Stateful Intrusion Detection in High Traffic Networks
White Papers These issues are critical especially for Network Intrusion Detection Systems (NIDS) that need to trace and reassemble every connection, and to examine every packet flowing on the monitored link(s), to guarantee high security levels.

SIFT: Snort Intrusion Filter for TCP
White Papers High-level intrusion rules mapped directly into hardware separate malicious content from benign content in network traffic. In this paper, a Snort Intrusion Filter for TCP (SIFT) is presented that operates as a preprocessor to prevent benign...

IPS Vs. IDS: Similar on the Surface, Polar Opposites Underneath
White Papers A common notion is that an Intrusion Prevention System (IPS) is nothing more than an Intrusion Detection System (IDS) deployed in-line with blocking capabilities. Although IPS and IDS both examine traffic looking for attacks, there are critical...

Target-Based TCP Stream Reassembly
White Papers The authors revealed that intrusion detection systems cannot be effective and accurate because they do not necessarily process, or perhaps, even observe network traffic exactly as the destination host that receives the message does.
