How many devices in your office are connected to the Internet? You have your laptops, desktops, and phones, but what about printers, cameras, and thermostats? The fact is that almost every device we use today has some level of internet connectivity. This means your business could be full of Internet of Things (IoT) devices and the security risks that come with them.
Worldwide, studies estimate about 75 billion devices are connected to the Internet, all offering a connection to someone else’s data. And while it might seem weird to think about a data breach happening through a printer or coffee machine, cybercriminals see these as unprotected entry points into a business’s network.
Here’s why IT support services providers throughout the US are encouraging businesses to take a second look at their IoT devices.
What Makes IoT Devices Vulnerable?
If you were a bank robber, would you prefer to go in the heavily guarded front door or the small basement window that everyone’s forgotten about? IoT devices are often considered the small basement window.
They’re easy to hack and offer access to a company’s network or data, but many businesses don’t even consider protecting them. IT support services providers are worried about IoT devices impacting small businesses because of these vulnerabilities:
- Lack of Built-In Security Features: Many IoT devices are designed with basic functionality in mind, often sidelining advanced security protocols. Devices like smart thermostats, security cameras, and sensors may leave gaps that hackers can exploit.
- Default Passwords and Outdated Firmware: A startling number of IoT devices continue to operate with their factory-set credentials or outdated firmware, making them an easy target for unauthorized access.
- Connections to Critical Systems: IoT devices are often interconnected with business-critical systems. If one device is compromised, it can serve as a gateway for attackers to access your broader network, amplifying the impact.
How Do Hackers Use IoT Devices to Access Data?
Let’s use a smart thermostat hacking as an example. By exploiting weaknesses such as unencrypted communication or insecure APIs, a hacker can gain control of the thermostat. From there, they can explore the network it’s connected to, scanning for other vulnerable devices or accessing business-critical systems.
This could look like:
- Accessing sensitive company data stored on a connected server.
- Launching a ransomware attack, demanding payment for the return of critical business files.
- Installing malware that can spread throughout the network and disrupt day-to-day operations.
And since thermostats often carry detailed usage patterns and location data, attackers may also use this information for other targeted attacks. Think of IoT devices as an unlocked backdoor to your business’s network, providing attackers with an easier way to breach your systems.
Best Practices to Secure Your Business’s IoT Devices
To protect your business from these risks, here are seven best practices from IT support services providers that you can implement immediately.
1. Change Default Credentials
Out-of-the-box devices often come with default usernames and passwords, which are widely known and easy to exploit.
Replace default credentials with strong, unique passwords that include a mix of letters, numbers, and special characters. Consider using a password manager to keep track of complex credentials.
2. Keep Firmware and Software Updated
Manufacturers regularly release firmware updates to address vulnerabilities and improve device security. Failing to update can leave devices exposed.
Set reminders to check for updates regularly or enable automatic updates when available.
3. Segment Your Network
Segregating your IoT devices from your critical systems can limit the extent of damage if a device is compromised.
Use a separate network or VLAN specifically for IoT devices to create an extra layer of isolation.
4. Enable Encryption
Encryption ensures that sensitive data transmitted between devices and networks cannot be accessed by unauthorized parties.
Use end-to-end encryption wherever possible and verify that your devices support secure communication protocols like TLS (Transport Layer Security).
5. Implement Access Controls
Restricting access minimizes the chances of unauthorized users tampering with your devices.
Assign access levels based on roles and responsibilities, ensuring only authorized personnel can modify device settings.
6. Monitor and Audit Devices Regularly
Continuous monitoring allows you to detect unusual patterns of behavior that might indicate a security breach.
Use monitoring tools to track IoT device activity and conduct regular audits to ensure all devices are compliant with your security standards.
7. Disable Unnecessary Features
IoT devices often come with features you don’t need, many of which can open pathways for hackers if left active.
Review your devices and disable any features you’re not actively using, such as remote access or data logging.
