Abstract
A data processor includes an input/output bridge that provides enforcement of a security status on transactions between devices across the bridge. The bridge includes circuitry to parse a received request to obtain one or more identifiers, and compare the identifiers against one or more programmable lookup tables. Based on this comparison, the bridge can determine the security status of the transaction, as well as selectively forward the transaction based on the security status.
