Malicious boot firmware is a largely unrecognized but
significant security risk to our global information infrastructure.
Since boot firmware executes before the operating
system is loaded, it can easily circumvent any operating
system-based security mechanism. Boot firmware programs
are typically written by third-party device manufacturers
and may come from various suppliers of unknown origin. In
this paper we describe an approach to this problem based
on load-time verification of onboard device drivers against
a standard security policy designed to limit access to system
resources. We also describe our ongoing effort to construct
a prototype of this technique for Open Firmware boot platforms.
