Secure communication in a connected world

The future of the Internet of Things (IoT) means billions of devices must communicate with application servers via the internet, and with each other, without the need for people to get involved. With that comes a host of software, firmware and hardware that must be integrated to ensure each device is speaking the same language—and that security isn’t left out of the conversation, either. Even the most experienced IT departments don’t always have the capabilities in-house to tackle the biggest questions around connectivity and security.

Connectivity is key in IoT

What is IoT without the connection that brings devices together? It’s crucial for people and systems to be able to extract information out of an IoT solution, whether it’s a custom or standards-based IP network.

Network topology has grown past point-to-point to consider additional network setups such as star, bus and mesh. Whether every endpoint connects to a single gateway or there are multiple linking points, there’s a tremendous amount of data in any IoT deployment. All that networking allows devices to speak different languages across communication protocols as varied as infrastructure or ad-hoc networking from WiFi, Thread, ZigBee and Bluetooth to Sigfox, LoRaWAN and more.

End-to-end security schemes are necessary for IoT communication

Security in IoT is more than just a software update or encrypted chip. You must consider a security scheme from the beginning of the product roadmap through deployment and updates. Whether considering a fitness tracking wearable or a global industrial IoT network, secure communication has three distinct characteristics:

  • Mutual authentication: each device or server within an IoT deployment should and can prove true and unique identities to each other to ensure safety of communication.
  • Message integrity: messages sent between devices and servers shouldn’t be able to be hacked, altered or changed by an interfering party to ensure data privacy.
  • Message confidentiality: messages should have the ability to be coded so only authorized parties have access to read them.

Companies worldwide are spending tens of billions on IoT security. Having a partner with experience in end-to-end in security can move you from initial product planning to designing, building, deploying and maintaining an IoT solution.
