4 Open and Free Disk and NAS Encryption Projects - page 2
DiskCryptor is another disk encryption solution. It offers encryption of entire disks, including the system partition, and CD/DVDs. The best part is that the partitions don't have to be empty. You can encrypt drives or partitions with existing data in place, even your system or boot partition.
If you do a lot of sharing on your network, network-attached storage (NAS) servers can be quite useful. They provide a central storage spot for the entire network. They give you better functionality and control over what simple file shares of Windows, Linux, or Mac OS X provide. However, don't forget about disk encryption. Thieves can still steal your NAS server, which is probably a gold mine of sensitive documents.
CryptoNAS is a Linux-based NAS server designed to encrypt the drives you use with it. It can turn pretty much any old PC into a secure NAS server. Simply insert a LiveCD or install onto an existing Linux machine.
You can create and mount the encrypted volumes via the web-based GUI by supplying a encryption password. Then the volume is accessible on computers in the network via a Samba (Windows) share, which works just like accessing a simple shared folder. You can also access the CryptoNAS shares via Linux, Mac OS X, and other OSs that support Samba shares. Once you unmount or restart the NAS server, the encrypted volumes are locked until the encryption password is provided.
Since CryptoNAS creates the encrypted disk partitions using the LUKS volume, they are also accessible directly in Linux or directly in Windows via FreeOTFE.
For help on using CryptoNAS, refer to a previous tutorial of mine on PracticallyNetworked, another Internet.com site.Eric Geier is the founder of NoWiresSecurity, which helps businesses easily protect their Wi-Fi networks with the Enterprise mode of WPA/WPA2 encryption. He is also a freelance tech writer, and has authored many networking and computing books for brands like For Dummies and Cisco Press.
