A method and apparatus are provided for controlling system management interrupts is disclosed. The method comprises: receiving an interrupt signal; determining a type associated with the interrupt signal; using the determined type to access control information indicating an action to be applied to the determined type of interrupt; and blocking, passing or remapping the interrupt signal in response to the control information. The apparatus comprises a memory, an interrupt unit and a logic circuit. The memory is adapted to store control information regarding a plurality of types of interrupt signals. The interrupt unit is adapted to receive the interrupt signal, and use the interrupt type contained in the interrupt signal to access the control information stored in the memory. The logic circuit is adapted to block, pass or remap said interrupt signal in response to the control information.
