Full-Disk-Encryption Crash-Course

Everything to hide

This is not a hacking presentation, no vulnerabilities are presented. It's a crash-course in full-disk-encryption ("FDE") concepts, products and implementation aspects. An overview of both commercial and open-source offerings for Windows, Linux, and MacOSX is given. A (programmer's) look at the open-source solutions concludes the presentation.

Full-Disk-Encryption is an important aspect of data security and everyone should use an appropriate solution to protect their (especially mobile) systems and data. This lecture covers the technology behind Full-Disk-Encryption software products.

The established technical architectures of software solutions for Microsoft Windows and Linux are presented in this lecture: Pre-Boot-Authentication, encryption driver and in-place filesystem encryption.

An overview of commercial products and open-source offerings for Windows, Linux and OSX is given. Distinguishing features of specific products and additional topics are covered, including: TPM support (OS binding and key storage), multi-disk support and threats.

The last segment of the lecture focuses on open-source solutions: TrueCrypt's volume specifications, TrueCrypt's hidden volume capabilities and a comparison of in-place filesystem encryption implementations of TrueCrypt and DiskCryptor. A feature wish-list for open-source Full-Disk-Encryption solutions completes the lecture.
