How To Add WiKID Two-Factor Authentication To The Astaro Security Gateway
Astaro is a very popular Linux-based "all-in-one" security appliance offering spam filtering, malware protection, firewall, VPN, etc. The WiKID Strong Authentication Server is a dual-source two-factor authentication system. PINs are encrypted on a software token and sent to the WiKID server. If the PIN is correct, the encryption valid and the account active, a one-time password is generated, encrypted and returned to the user's token where it is decrypted and presented for use with a network-based services. This document will show how to add WiKID two-factor authentication to the Astaro Security Gateway version 7 using Radius.
Protect Your Files With TrueCrypt 5.1a On Debian Etch (GNOME)
This document describes how to set up TrueCrypt 5.1a on Debian Etch (GNOME). Taken from the TrueCrypt page: "TrueCrypt is a software system for establishing and maintaining an on-the-fly-encrypted volume (data storage device). On-the-fly encryption means that data are automatically encrypted or decrypted right before they are loaded or saved, without any user intervention. No data stored on an encrypted volume can be read (decrypted) without using the correct password/keyfile(s) or correct encryption keys. Entire file system is encrypted (e.g., file names, folder names, contents of every file, free space, meta data, etc)."

How to add two-factor authentication to Google Apps for your Domain using open source software

Webmail is very convenient, but for frequent travellers and those who use public wifi, it can be quite dangerous. Logging in from a kiosk or shared computer is a sure way to get your username and password stolen by a keystroke logger. Using a public WiFi system can lead to a man-in-the-middle attack. In this document we will take advantage of two open source projects to add two-factor authentication to Google Apps. The first is Gheimdall, a a TurboGears project for Google Apps SSO service. Gheimdall supports PAM and LDAP authentication natively. It also includes sample code to add new authentication methods, which made it very easy to add two-factor authentication from WiKID. WiKID is a dual-source two-factor authentication solution that uses public key cryptography to strongly authenticate users.
