Lights, Cameras…Vulnerabilities? Rise of Non-Business IoT Devices Putting North American Corporate Networks At Risk

IoT survey from Palo Alto Networks highlights the need for shared responsibility among remote workers and IT teams to secure their enterprise

TORONTO, Oct. 20, 2021 /CNW/ -- Cyber adversaries know that one small IoT sensor can provide entry into a corporate network to launch ransomware attacks and more. According to a survey of IT decision-makers by Palo Alto Networks (NYSE: PANW), 84% of respondents in North America (among those whose organization has IoT devices connected to its network) reported an increase in non-business IoT devices on corporate networks in the last year. Smart lightbulbs, heart rate monitors, connected gym equipment, coffee machines, game consoles and even pet feeders are among the list of the strangest devices identified on such networks in the study.

For the second year, survey responses warn of needed security changes to protect corporate networks from non-business IoT devices. This year, 96% of the same group above indicated their organization's approach to IoT security needs improvement, and 1 in 4 (25%) said it needs a complete overhaul with the greatest capability needs around threat protection (59%), risk assessment (55%), and IoT device context for security teams (55%).

"IoT adoption has become a critical business enabler. It presents new security challenges that can only be met if employees and employers share responsibility for protecting networks," said Ivan Orsanic, regional vice president and country manager, Canada at Palo Alto Networks. "Remote workers need to be aware of devices at home that may connect to corporate networks via their home router. Enterprises need to better monitor threats and access to networks and create a level of segmentation to safeguard remote employees and the organization's most valuable assets."

Worth noting, of the 400 North American IT decision-makers polled by Palo Alto Networks this year that have IoT devices connected to their network, half (50%) indicated that IoT devices are segmented on a separate network from the one they use for primary business devices and business applications (e.g. HR system, email server, finance system, etc.), and another 29% of respondents said that IoT devices are microsegmented within security zones — an industry best practice where organizations create tightly controlled security zones on their networks to isolate IoT devices and keep them separate from IT devices to avoid hackers from moving laterally on a network.

Top 3 IoT Security Tips for the Work-from-Home (WFH) Employee

  1. Get more familiar with your router. All of your connected devices likely connect to the internet through your router. Start by changing defaults — the settings every router comes with — to something unique. Then encrypt your network by simply updating your router settings to either WPA3 Personal or WPA2 Personal. 
  2. Keep track of which devices are connected. You can access your router's web interface and look for "connected devices," "wireless clients" or "DHCP clients" to see a list and disconnect older devices you no longer use, and disable remote management on the devices where you don't need it.
  3. Segment the home network. Network segmentation is not only for large corporations. You can segment your home network by creating a guest Wi-Fi network. The easiest way to do this is to have IoT devices use a guest Wi-Fi network, while other devices use the main network. This helps to logically group devices in your home and isolate them from each other. Keeping them on a separate network makes it difficult to get to your computers from a compromised IoT device. 

Top 3 IoT Security Tips for the Enterprise

  1. Know the unknowns. Get complete visibility into all IoT devices connected to the enterprise. An effective IoT security solution should be able to discover the exact number of devices connected to your network, including the ones you are and are not aware of — and those forgotten. This discovery helps collect an up-to-date inventory of all IoT assets. 
  2. Conduct continuous monitoring and analysis. Implement a real-time monitoring solution that continuously analyzes the behaviour of all your network-connected IoT devices to contextually segment your network between your IT and IoT devices — and their workloads. Securing and managing WFH setups as branch extensions of the enterprise requires a new approach.
  3. Automate risk-based security policy recommendations and enforcement. An IoT security solution should be easy to deploy without the need for any additional infrastructure or investment. Look for a solution that leverages your existing firewall investment for comprehensive and integrated security posturing. Running in conjunction with the capabilities of your firewall, the solution should automatically recommend and natively enforce security policies based on the level of risk and the extent of untrusted behaviour detected in your IoT devices. An IoT security strategy should also align with the principle of Zero Trust to enforce policies for least-privileged access control. Additionally, a point solution can extend a corporate network and bring unified security policy management and SASE (secure access service edge) to WFH employees. 

Palo Alto Networks helps secure IoT devices with IoT Security, which combines machine learning with patented App-ID™ technology to provide the most accurate and deepest level of visibility into your IoT and OT devices for effective baselining of their normal behaviors. The solution empowers security teams to proactively prevent threats, monitor device risk, detect anomalies, and recommend then apply policies for enforcement.
