History

Richard Hughes 7d132b728c Simplify the quirk file format The best way of not getting something wrong is to not require it in the first place... All plugins now use DeviceInstanceId-style quirk matches and we can just drop the prefix in all files. We were treating HwId=, Guid= and DeviceInstanceId= in exactly the same way -- they're just converted to GUIDs when building the silo!		2021-03-03 08:30:34 +00:00

MSR

Introduction

This plugin checks if the Model-specific registers (MSRs) indicate the Direct Connect Interface (DCI) is enabled.

DCI allows debugging of Intel processors using the USB3 port. DCI should always be disabled and locked on production hardware as it allows the attacker to disable other firmware protection methods.

The result will be stored in a security attribute for HSI.

External interface access

This plugin requires read access to /sys/class/msr.
