An apparatus and method are provided for implementing one or more security services to messages and data being communicated between a first network and a second network. In particular, a network bridge device is provided for applying communications security services to data passing by means of the device from a first network to a second network, the device having a first network interface for linking to the first network, a second network interface for linking to the second network, and a unidirectional link between the first and second network interfaces within the device incorporating a first hardware logic module, configured to apply one or more predetermined data security functions to message data received via the first network interface, and a second hardware logic module, arranged to apply a predetermined scheme for authentication of the source of messages passing through the device.
