Any discussion of security is dependent on context. This report will discuss security issues associated with migrating M2M/IoT communications to cellular technologies or creating a new M2M/IoT product using cellular communications. Historically most M2M communications were focused around proprietary protocols, private networks, leased lines and POTS.
Some systems have moved to local LANs and TCP/IP . Now they are moving to Internet access and cellular connectivity. Most efforts to date are focused on just getting things to work with only minimal consideration to overall system security. Most cellular modems today connect directly to the Internet with less protection than the average home PC. Even products that do have some threat protection are still at risk of unanticipated data consumption. This paper will discuss ways to avoid some of the threats to M2M/IoT communications systems and ways to mitigate others.
