A new cryptographic filesystem in the Linux kernel uses stacking technology.

FiST

The Stony Brook University (SUNY) File Systems and Storage Labs (FSL) (filesystems.org) has developed a stacked filesystem framework called FiST. eCryptfs is derived from Cryptfs, which is one of the example filesystems implemented in FiST. Unionfs is another popular stacked filesystem written by the SUNY FSL.

This article is on page 54 of the print edition. I recommend picking up a copy; there are several good security-related articles in there.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6

Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.
