There is provided an integrity monitor configured to monitor the integrity of a component protection device. The component protection device comprises a protective medium to protect at least one electronic component, and having associated therewith a magnetic element and a Hall Effect sensor. The at least one of the magnetic element and the Hall Effect sensor is embedded within the protective medium and the Hall Effect sensor is located, when in use, to sense a magnetic field generated by the magnetic element. The integrity monitor has an input for receiving an output of the Hall Effect sensor indicative of the sensed magnetic field and the integrity monitor is configured to identify from the received output any change to the sensed magnetic field and determine, based on the change to the sensed magnetic field, an integrity of the component protection device.
