Businesses are rapidly adopting IoT technologies and their IT departments are desperately trying to keep up, potentially creating security risks if they are not implemented properly. One prominent IoT technology is smart sensors. These devices are used to monitor a multitude of things including, security, motion, light, and temperature. Smart sensors can be deployed by the thousands and each are a potential portal into business’ IT network. While nothing is hack-proof, here are five steps to make an intrusion into your network less likely.
1. Independent Network
The recommended Sensing-as-a-Service strategy is to have smart sensor networks be independent of enterprise networks. This practice has been used successfully by national healthcare, retail, and pharmaceutical chains to prevent intrusion.
2. Robust Encryption
Wireless sensors can communicate to a gateway via mesh or star networks. Using 128 bit encrypted IEEE 802.15.4 type sensors to transmit data, combined with a secure, encrypted cellular network offers a high-level of protection from intrusion. This strategy eliminates direct connections between the sensor network and the enterprise network.
3. Role-based User Credentials
A well-planned and implemented role-based user matrix enables companies to maintain security and information access. This strategy prevents lower-level users from having access to sensitive information or pathways into the enterprise network.
