Abstract
A technique includes detecting a presence of a hardware security module in a computer. The hardware security module performs trusted computing base measurements in response to the boot of the computer. The technique includes detecting an intention to change firmware of the computer and regulating providing a message warning about an impact of the change based on the determination. The regulation includes determining whether an operating system of the computer binds operations to the trusted computing base measurements and allowing communication of the message based on the determination.
