AMaViS (A Mail Virus Scanner) scans e-mail attachments for viruses using third-party virus scanners available for UNIX environments. It resides on a UNIX (Linux) machine and looks through the attached files arriving via e-mail, generates reports when a virus is found and sets the delivery on hold.
The Bait and Switch Honeypot System combines the snort Intrusion Detection System (IDS) with honeypot technology to create a system that reacts to hostile intrusion attempts by marking and then redirecting all "bad" traffic to a honeypot that partially mirrors your production system. Once switched, the would-be hacker is unknowingly attacking your honeypot instead of the real data, while your clients and/or users are still safely accessing the real system. Life goes on, your data is safe, and you get to learn about the bad guy as an added benefit. It works with Snort 1.9.0, 1.9.1, and 2.0.2.
CCSAT (Cisco Configuration Security Auditing Tool) is a tool for automated auditing of configuration security for large numbers of Cisco routers and switches. The tool is based upon industry best practices, including Cisco, NSA, and SANS security guides and recommendations. It is flexible and can report details down to individual device interfaces, lines, ACLs, and ASs, etc. This tool has been tested and used successfully on FreeBSD, Solaris 8, and Linux, and should work on all major UNIX platforms (POSIX.2).
CODEX (the Cornell Data Exchange) is a key distribution system. It is designed for applications with a moderate number of clients (tens or hundreds) requesting keys that change often but not continuously (on the scale of minutes to hours). It employs the RSA and ElGamal encryption schemes, as well as techniques such as threshold cryptography and proactive secret sharing.
Cisco Template Manager (CTM) is a set of tools that make it easy to manage Cisco configurations over a whole network based on your self-defined templates. With CTM you will have a unified configuration in your entire network, which is the basic building block of operational stability and security. The pre-defined templates support regular expressions. It supports the C760x, C730x, C37xx, C35xx, C29xx, C28xx, C18xx, and C17xx family series.
The DansGuardian Anti-Virus Scanner gives you the ability to virus-scan all content that passes through DansGuardian. It uses the scanning code from the MailScanner project to do the actual virus scanning, so it supports all the virus engines that the MailScanner project supports. The scanning is done as the file is being downloaded, so your current network apps don't have to be modified, etc. They just have to support using a proxy.
