Are you confident that your enterprise networks are secure? If so, can you be certain all approved IoT devices are accounted for and properly configured? It’s essential to identify every device connected to your network if only to ensure that it is not a malicious actor.

But identifying unauthorized network intruders is not the only reason for carefully inspecting your enterprise networks.

In this article, I’ll provide 3 tips for locating and identifying any Internet of Things (IoT) Devices on your enterprise networks. These tips will help you reduce vulnerability across your entire organization and ensure maximum data security.

Scan The Network

One of the best ways to locate and identify IoT devices on your enterprise networks is to scan the network for any active connections. This can be done using various tools such as nmap or a vulnerability scanning product. By scanning the network, you can see which devices are connecting to your network and get some idea of what they might be. Some tools, including nmap can guess the type of device it might be based on stack fingerprinting or services identified.

Scan For BlueTooth Devices

Many IoT devices use Bluetooth to connect to other devices or interact with users, and scanning for such devices can help you locate them. You can use a tool such as BLE Scanner to detect any active Bluetooth devices connected to your network. This will help you identify unapproved or unauthorized Bluetooth-enabled IoT devices on your networks.

Inventory MAC Addresses And ARP Data

Every IoT device connected to your network has a unique MAC address. By keeping an inventory of all the active MAC addresses, you can quickly identify any new or unauthorized devices connecting to your networks. Additionally, you should monitor ARP data for changes or anomalies. Detecting any suspicious activity could indicate that a malicious actor or unexpected device is attempting to connect to your network.

To look up the MAC address and identify the vendor of an IoT device, you can search using the MAC address on websites such as macvendors.com, which will show you who manufactured the device. Some network security and monitoring systems may also provide a way to look up MAC addresses, allowing you to identify any unauthorized devices on your enterprise networks quickly.

In conclusion, ensuring that all IoT devices connected to your enterprise networks are identified and adequately configured is essential. To do this, you should scan the network for active connections, scan for Bluetooth devices, and inventory MAC addresses and ARP data.
