Device selection criteria
A common concern with IoT devices is that they could be the weakest link that enables attackers to break into an Edge network.
Thus, it's important to consider two standards when choosing devices. One is that it has a well implemented Security Development Lifecycle (SDL), a concept introduced by Microsoft to consider security and privacy concerns throughout the entire software development process.
Next is IEC 62443, an internationally accepted standard that lays down process requirements for the secure development of products used in industrial automation and control systems as well as Edge IT applications.
Secure network design
Rather than a one-size-fits all approach, a Defence-in-Depth Network (DDN) approach can help diversify risks by creating security zones with different defensive elements in each zone.
