Abstract

Broadly speaking, embodiments of the present technique provide apparatus, systems and methods to enable secure communication between devices. In particular, the present techniques provide an apparatus configured to monitor for a data packet transmitted between a transmitter and a receiver, determine if the data packet is permitted to be transmitted, and act on at least part of the data packet to prevent the receiver from acting on the data packet if it is not permitted to be transmitted. In other words, the present techniques provide/implement security filters in a communication channel between a transmitter and a receiver to reduce the risk that unauthorised data packets are sent to, and implemented by, the receiver device.

Dependent claims

A method of filtering data packets transmitted between a transmitter device and a receiver device, the method comprising:

monitoring, at a node device arranged between the transmitter device and the receiver device, a data packet transmitted from the transmitter device to the receiver device;
determining, at the node device, if the monitored data packet is permitted to be transmitted between the transmitter device and the receiver device;
distorting, responsive to the determining, at the node device, at least part of the monitored data packet if the monitored data packet is not permitted to be transmitted.
