History

Richard Hughes e87fc05ab9 Speed up the daemon startup by ~2% by doing dlsym much less We were calling g_module_symbol() 2703 times, which is actually more expensive than you'd think. It also means the plugins are actually what we tell people they are: A set of vfuncs that get run. The reality before that they were dlsym'd functions that get called at pretty random times.		2021-11-09 12:02:07 +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.
