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.
