The Importance of Segregated Networks for IoT Devices
In today’s world, almost every new device requires an internet connection or the creation of an account to function. From smart thermostats to connected coffee makers, the age of the “Internet of Things” (IoT) is upon us. While these devices bring convenience and innovation, they also introduce potential risks to your business or home network security.
It’s crucial to understand why separating your IoT devices from your main network is important and how to do it effectively.
Why Separate Your IoT Devices?
IoT devices, while useful, can be vulnerable to cyberattacks. Unlike computers or smartphones, many IoT devices lack robust security features. If a cybercriminal gains access to one of your IoT devices, they could potentially infiltrate your entire network, accessing sensitive business information. By segregating IoT devices onto a separate or “Guest” network, you create a barrier that protects your main network from potential breaches.
While convenient,IoT devices can generate a significant amount of network traffic, potentially slowing down your main network. By placing these devices on a separate network, you ensure that your critical business operations aren’t impacted by the traffic generated by IoT devices.
Best Practices for Setting Up Internet Connected Devices
1. Use a Dedicated Guest Network: Most modern routers allow you to create a guest network. This network is isolated from your main network, providing an additional layer of security. Ensure that your IoT devices are connected to this guest network rather than your primary business (or personal) network.
2. Strong Passwords: Set strong, unique passwords for your guest network connection and IoT devices. Avoid using default passwords for products or services, as these are easily guessable and a common target for cybercriminals. A quick google search can give popular or default username/password combinations for devices.
3. Regular Updates: Ensure that your IoT devices are regularly updated with the latest firmware and security patches. Manufacturers release updates to address vulnerabilities and improve device security and functionality. Keeping devices updated will patch holes that the developer is aware of to prevent exploitation by hackers.
4. Monitor Network Traffic: Keep an eye on the traffic and behavior of your IoT devices. Unusual activity could indicate a security issue that needs immediate attention. Network monitoring tools may be needed for in-depth investigation, but if you find your devices creating a lot of chatter across the network it may be good to try and investigate further.
5. Limit Device Permissions: Only grant the necessary permissions to your IoT devices. For example, if a device doesn’t need internet access, disable it. This reduces the risk of unauthorized access and can be toggled on later if needed in the future.
Creating Accounts for IoT Devices
Setting up accounts for your devices may be something you do without much thought. Change that approach. By strengthening a few steps in the account creation process, you can thwart hackers.
1. Use Unique Email Addresses: When creating accounts for IoT devices, use unique email addresses for each device or service. This practice helps contain potential security breaches and makes it easier to manage device-specific settings. At minimum, a service email should be created separate from any standard user’s email account.
2. Enable Two-Factor Authentication (2FA/MFA): Whenever possible, enable two-factor authentication for accounts associated with IoT devices. 2FA adds an extra layer of security, making it harder for unauthorized users to access your accounts even if they know your password.
3. Review Privacy Settings: Take the time to review and adjust the privacy settings in the device. Opt for the highest level of privacy and limit data sharing to what’s strictly necessary for the device to work. Only enable options you know for sure you will use and are aware of the risk.
4. Regular Account Audits: Periodically review the accounts associated with your IoT devices. Remove any old or unused accounts to minimize potential security risks. Old devices should also be disposed of if no longer in use to reduce chances of security holes.
Proactive Security is Your Best Protection
In the rapidly evolving landscape, it’s vital to take preemptive steps toward network security. By segregating your IoT devices onto a dedicated guest network and following best practices for connecting and managing these devices, you can protect your business from potential cyber threats and ensure smooth, uninterrupted operations.
Remember, taking these steps not only safeguards your sensitive business data but also provides peace of mind in knowing that your network is secure. Embrace the benefits of IoT with confidence by prioritizing security and vigilance.
