Does My SMB Need a Separate Network for IoT Device Security?

Summary: How the Internet of Things affects computer network security, and what small and midsized businesses (SMBs) need to do to protect their data.

Does the Internet of Things Put Your Business Data at Risk?

Smart device technology continues to evolve and make more and more previously mundane tasks easier and more convenient. However, smart device vendors have sent many products to market that have low or non-existent cybersecurity protections in place. Weak security and factory-default passwords have opened new doors for cybercriminals.

Any device connected to your network is a vulnerable endpoint, and smart devices are no different. Smart thermostats, smart televisions, smart lightbulbs, self-driving vehicles, smart refrigerators, app-controlled toys, and smart vacuum cleaners are just a small sampling of connected smart devices available. They’re all part of the Internet of Things (IoT), but do we really need to worry about IoT device security? Absolutely. A lack of protection for networked devices poses a risk not only for your business but also your clients, customers, and vendors.

Q: What are IoT devices and why do they pose security risks?

A: IoT devices include connected tools like smart cameras, thermostats, printers, and sensors that communicate over the internet. They often lack strong built-in security, making them attractive entry points for cybercriminals. If compromised, these devices can expose networks, leak data, or enable broader system attacks.

Computer Network Security for Smart Devices

Consider a hypothetical question: Does it make sense for your smart vacuum cleaner to be on the same network as your business PCs? Of course, the answer is no. Connecting smart devices to the same network that is home to your SMB’s private data is a high risk. You might have state-of-the-art network protection for your business network. However, new hacking opportunities arise with the addition of every new smart device endpoint.

Consider this, too: In 2020 more than 30% of all cybercrime was initiated through networked smart devices. That’s more than double the number of 2019. Unfortunately, regulations governing smart device security have not kept up with the rapidly growing market. As a result, smart device manufacturers have not been motivated to spend money on tightening security for their devices but instead have taken advantage of the lack of regulatory control.

Q: Why is network segmentation important for IoT devices?

A: Network segmentation involves separating IoT devices from core business systems on different networks. This limits the damage if a device is compromised, preventing attackers from moving laterally across systems. It adds an extra layer of protection, helping contain threats and safeguard sensitive data and operations.

IoT Device Security: Do I Need a Separate Network for IoT?

There are several ways in which you can take control of your IoT network protection:

Create a Guest Network on Your Router – Most routers provide the option for users to configure a “Guest Network.” This feature is commonly used to allow non-employees and other guests to log onto your business network without accessing any of your company’s data. However, you need to secure your guest network with the same care and diligence you’ve applied to secure your primary network. It is also essential to create a strong username and password and deny most of the permissions and resources usually available to users of your primary local business network.

Configure Two Completely Separate Networks on One Router – Another option is using one router for two separate networks. However, if you choose this option, you’ll have to spend money to get a separate network connection from your internet service provider.

Purchase Two Separate Routers – This option can get a little confusing and tricky. The user must keep track of which devices are on which network. Also, they have to devote extra attention toward keeping everything running through each router separately from the other.

Use a WiFi Network Tool to Configure a Separate Network – Network software can help configure a separate network. Ideally, this approach should be used only by IT professionals or power users with a level of tech expertise.

Q: How do software updates improve IoT device security?

A: Regular software and firmware updates patch known vulnerabilities and improve device defenses. Many IoT devices are overlooked when it comes to updates, leaving them exposed to known exploits. Keeping devices updated ensures they have the latest protections and reduces the risk of successful cyberattacks.

How Do You Get Started with Computer Network Security?

SMBs must take issues involving network security for IoT devices more seriously. Unfortunately, many businesses don’t make basic cybersecurity protocols a priority. Adding a new layer of connected smart devices doesn’t often make the list of security imperatives. Smaller companies don’t typically have the time or the budget for a full-time IT department. However, they also lack the expertise to take the necessary steps to protect all their cyber vulnerabilities.

Q: What are best practices for securing IoT devices in small businesses?

A: Best practices include changing default credentials, enabling encryption, updating firmware regularly, and disabling unnecessary features. Businesses should also monitor device activity and limit access permissions. Taking these steps helps reduce vulnerabilities and ensures IoT devices do not become weak points within the broader network.
