Abstract:
In one embodiment, an apparatus includes a channel filter and a security processor. The security processor is to: receive a plurality of device access control policies from a protected non-volatile storage of a platform; determine whether the plurality of device access control policies are verified; program the channel filter with a plurality of filter entries each associated with one of the plurality of device access control policies based on the determination; and remove a security attribute of the security processor from a policy register of the channel filter, to lock the channel filter for a boot cycle of the platform. Other embodiments are described and claimed.
