Open standards were supposed to drive interoperability of Internet of Things devices, allowing cybersecurity software to interrogate devices across the network. Many vendors even hoped to install apps or agents inside IoT nodes; after all mobile devices allow this. Yet none of these approaches, APIs, or standards that products are built upon achieved wide adoption. With so little control and visibility into IoT, the coming wave of 5G devices should make security professionals nervous.
In response to 5G's potential to exacerbate an already complex problem of IoT security, researchers in defense and academic circles have launched programs to jumpstart R&D. This summer, the Defense Advanced Research Projects Agency (DARPA) released IoT research grants. And in a separate but parallel development, academic researchers at the Association of Computing Machinery (ACM) simultaneously launched a program allowing industry IoT experts to collaborate with academic researchers.
5G Will Soon Redefine CybersecurityGartner notes that the number of 5G IoT devices will expand from today’s 3.5 million units to 49 million in 2023. Gartner's past IoT predictions have been solid, though 5G has encountered curveballs, such as the impact of US sanctions on China's 5G mega-provider, Huawei, not to mention the uneven rollout of 5G service in North America.
Unsolved security issues can also hinder adoption. Analyst firm Omdia recently asked enterprise organizations about their biggest challenge in deploying IoT. The top answer: ensuring data, network and device security. This new world of 5G IoT devices will represent exceptional challenges for vulnerability management, threat hunting, and incident response.
