Fingerbank provides a suite of tools designed to recognize network devices through their unique network fingerprints. These fingerprints are essential for various applications, such as allowing Network Access Control systems like PacketFence to adjust network permissions according to the type of device connected, whether it be a gaming console or a laptop. Fingerbank understands how devices typically behave on a network, including their communication patterns, and can detect when a device strays from these expected behaviors. Our technology continuously mines data to identify common patterns among networking devices, which enables us to issue alerts if a device exhibits unusual activity. When a device connects to a network, it reveals valuable information across multiple layers of the networking stack. The Fingerbank collector is capable of creating an accurate fingerprint of the device and leveraging the knowledge and algorithms from the Fingerbank cloud API to precisely identify it. This capability not only enhances security but also facilitates better network management by ensuring that the right devices have appropriate access levels.
