Abstract
An integrated circuit chip comprising: system circuitry comprising interconnect circuitry for transporting transactions; and monitoring circuitry configured to: monitor transactions from the interconnect circuitry comprising transactions between an entity and a specified region of the integrated circuit chip, the entity being associated with a set of one or more access rights for accessing the specified region of the integrated circuit chip; determine from the monitored transactions values of one or more parameters associated with the access to the specified region by the entity to identify whether the entity has breached its access rights; and perform a dedicated action indicative of a breach of the access rights in response to determining from the parameter values that the entity has breached its access rights.
