Internet of Things (IoT) devices are versions of typically analog devices with added internet connectivity. These can be anything from cloud-connected thermostats and security cameras to door locks and even refrigerators. But while IoT devices have increased capabilities, they also come with significantly greater security risks for your business.
Let’s look at the current IoT threatscape and go over how you can secure your workplace’s IoT devices to prevent a devastating cyberattack.
What are the risks associated with IoT devices?
Unlike servers, computers, and mobile devices, IoT devices are rarely built with cybersecurity as a priority. This is often due to cost constraints or a lack of foresight by creators, who may not have anticipated credible threats targeting these devices. Unfortunately, cybercriminals are sly — they will attack IoT devices to disrupt your business and steal your hard-earned money.
Some of the ways they accomplish this are:
- Device hijacking: Hackers can gain control of a device and use it to interfere with your operations or extort you with the threat of damage. Such risks become particularly dangerous when organizations rely on IoT devices for safety purposes, such as cloud-connected sensors in manufacturing settings.
- Spying: Cybercriminals who gain access to your IoT devices can collect data from your company that they can sell or use to attack you. For instance, IoT security cameras can be hijacked to find blackmail material.
- Backdoor intrusions: If your IoT devices are connected to your wider IT network, cybercriminals could compromise these devices and use them to deliver malware.
How to secure your organization’s IoT devices
Take the first steps to secure your IoT devices with these simple actions that will minimize your risk:
Audit all devices
Start by taking a thorough inventory of all your IoT devices and setting them to “discoverable by all.” While this might initially seem counterintuitive, it’s crucial for identifying every device connected to your network and pinpointing their locations to maintain security. Remember, making a device discoverable doesn't equate to making it vulnerable.
Eliminate unused devices
If your audit reveals unused or underutilized IoT devices, it’s best to remove them. Every inactive device poses a potential security risk, especially when neglected. As devices age, the likelihood of cybercriminals exploiting vulnerabilities increases, making proactive removal a crucial step in protecting your network.
Invest in secure devices
Not all IoT devices suffer from weak security, but only some are equipped with robust built-in cybersecurity features. Protect your investment by choosing devices designed with security in mind. However, even secure devices may not be fully protected straight out of the box. Take the time to properly configure their security settings before connecting them to your network for optimal protection.
Set a regular update schedule
Unlike desktops and other primary devices, IoT devices rarely update their software or firmware automatically. Firmware, in particular, requires regular attention, as updates often need to be applied manually to keep devices secure and functional.
Practice network segmentation
Network segmentation entails splitting an organization’s network into smaller, separate segments to enhance security and simplify management. If malware or a cyberattack breaches your defenses, segmentation acts as a barrier, effectively stopping the threat from spreading. As a rule of thumb, do not connect your IoT devices to the same network where you store sensitive data and critical systems.
