APPLYING FILTER RULES IN LPWA COMMUNICATION NETWORKS

摘要

The invention relates to a communication device (110) for communicating data over a low power wide area, LPWA, communication network, wherein the communication device (110) comprises: a processor (111) configured to process data; a memory (113, 115) configured to store data; a radio (117) configured to transmit and/or receive data over the LPWA communication network (100); and a security system. The security system is configured to operate one or more logically separated sets of security domains (111a-c, 113a-c, 115a-c), including a first set of security domains (111a, 113a, 115a), on the processor (111) and the memory (113, 115), wherein each set of security domains comprises a processor security domain (111a-c) and a memory security domain (113a-c, 115a-c), wherein the processor security domain (111a) of the first set of security domains (111a, 113a, 115a) is configured to monitor and/or control data to be transmitted by the radio (117) and/or data received by the radio (117) on the basis of a set of filter rules.
