Security continues to be a hot topic in all areas of technology, including machine-to-machine (M2M) applications. Today, most analysts agree that the security risk is relatively low, primarily because M2M is still a growing space and hasn’t reached a critical mass that would draw significant attention from hackers. However, M2M is growing very quickly. Cisco estimates that there will be 25 billion connected devices by 2015 and 50 billion by 2020, so security concerns will likely grow in the near future.
