External device risk is everywhere: how can enterprises block unauthorized devices from connecting through USB ports?
In many enterprises, a USB port looks like an ordinary physical interface. In practice, however, it is one of the easiest ways to weaken endpoint control without attracting immediate attention. An employee inserts a personal USB drive into a work laptop to copy a file. A contractor plugs in removable media to deliver materials. Research, finance, HR, and legal endpoints allow general USB devices to connect freely for years. In these situations, the enterprise data boundary is no longer being challenged through sophisticated network attacks. It is being opened directly at the endpoint through a simple hardware connection.
