OTFE on Linux, encrypting your data

Submitted by MarkAdams on Fri, 10/17/2008 - 15:46

I previously wrote about on the fly encryption, also known as OTFE in my article about using it on my PDA to encrypt data in case the device is stolen.

Today, I'm writing about OTFE for Linux servers. The benefits of OTFE are that you only have to type a password once, and then the encrypted data is easily accessible for the entire session. However, if someone steals your hard disk, the data is as secure as your encryption key.

An easy software SSL VPN solution for Linux

Submitted by MarkAdams on Tue, 10/21/2008 - 14:16

When I went on vacation recently, I was looking for a VPN solution that would be easily used from just about anywhere, and that was easy to install. I found the perfect solution in a product from 3SP Limited, a U.K. company.

A VPN is a virtual private network. In the most basic terms, it is a tool that makes a network that is accessible over a public network to be accessible as if you were on that private network. This is usually done by tunneling the traffic, securely, through the public network.
