Dear nixCraft, I carry my Linux powered laptop just about everywhere. How do I protect my private data stored on partition or removable storage media against bare-metal attacks where anyone can get their hands on my laptop or usb pen drive while traveling? -Sincerely,

Worried about my data.

That’s actually a great question. Many enterprises, small businesses, and government users need to encrypt their laptops to protect confidential information such as customer details, files, contact information, and much more. Linux supports the following cryptographic techniques to protect a hard disk, directory, and partition. All data that is written on any one of the following techniques will automatically encrypted and decrypted on the fly.
