An apparatus includes an interface and a processor. The interface is configured for communicating over a bus. The processor is configured to disrupt on the bus a transaction in which a bus-master device attempts to access a peripheral device without authorization, by forcing one or more dummy values on at least one line of the bus in parallel to at least a part of the transaction.
