  • Protecting and monitoring internal bus transactions
    Patent number: 10572675
    Abstract: A computing device includes a first component, a second component and a monitoring component. The monitoring component, receives, from the first component, a command to issue one or more transactions or data to the second component, and determines whether the first component is authorized to issue the one or more transactions, according to one or more policies or rules, which are received through an out-of-band mechanism to which the first component does not have access. If the monitoring component determines that the first component is authorized to issue the one or more transactions or data to the second component, it forwards the one or more transactions data to the second component. Otherwise, the monitoring component blocks the one or more transactions or data from being issued to the second component.
