Preventing Linux rootkit threats through secure boot design

The Linux OS is likely to become even more popular as 32bit computing becomes a commodity and projects like Yocto make it easier to create, develop and maintain Linux based systems for embedded applications.

One of the advantages of Linux is that it enables OEMs to become more like startups, where agile hardware development teams speed time to market by using an OS to abstract the underlying hardware details. However, despite its benefits, a Linux system can be vulnerable to rootkits unless its embedded processor is booted properly.
