Toriss is an IIS plug-in that makes the SMTP service immune to Reverse NDR Attacks. Instead of bouncing emails that are sent to invalid users, Toriss will reject the email as soon as the RCPT command is received. A Reverse NDR Attack can fill the mail queue with thousands of undeliverable bounce-backs, slowing down the whole system and making the SMTP service unresponsive. Toriss solves this problem completely.

The Snare Micro Server is a program that provides a central collection facility for a variety of log sources, including Snare Agents for Windows, Solaris, AIX, Irix, ISA Server, IIS Server, Lotus Notes (and others), plus any device capable of sending data to a syslog server.

Snare is currently used by hundreds of thousands of individuals, and organisations worldwide, and is free software with source available under the terms of the GPL.
