Securing SSH On Ubuntu Precise With WiKID Two-Factor Authentication

SSH offers a highly secure channel for remote administration of servers. However, if you face an audit for regulatory or business requirements, such as Visa/Mastercard PCI, you need to be aware of some potential authentication related short-comings that may cause headaches in an audit. In this document we are going to demonstrate how to combine two-factor authentication from WiKID on Ubuntu. This document will also serve as the basis for additional tutorials because many services on Linux use PAM for authentication.

How To Configure Apache To Use Radius For WiKID Two-Factor Authentication On Ubuntu

How To Configure Apache To Use Radius For WiKID Two-Factor Authentication On Ubuntu

This document describes how to add WiKID two-factor authentication to Apache 2.x using mod_auth_radius on Ubuntu 12.04 Precise. It is recommended that you consider using mutual https authentication for web applications that are worthy of two-factor authentication. Strong mutual authentication means that the targeted website is authenticated to the user in some cryptographically secure manner, thwarting most man-in-the-middle attacks. The use of cryptography is key. While some sites use an image in an attempt to validate a server, it should be noted that any man-in-the-middle could simply replay such an image.
