HLBR is a brazilian project, started in november 2005, as a fork of the Hogwash project (started by Jason Larsen in 1996). This project is destined to the security in computer networks.

HLBR is an IPS (Intrusion Prevention System) that can filter packets directly in the layer 2 of the OSI model (so the machine doesn't need even an IP address). Detection of malicious/anomalous traffic is done by rules based in signatures, and the user can add more rules. It is an efficient and versatile IPS, and it can even be used as bridge to honeypots and honeynets. Since it doesn't make use of the operating system's TCP/IP stack, it can be "invisible" to network access and attackers.

Since version 1.0, released in march 5th 2006, HLBR can use regular expressions to detect intrusion attempts, virus, worms, and phishing. To see an example of rule with regular expressions, click here. To see the README file click here.

You can use another program, called HLBRW. HLBRW will help you to make new HLBR rules. You can download it in HLBR repository, in the same place where are the HLBR files. To see the README file click here. To see the manpage, click here (txt2tags format).
