Abstract
Described are techniques for Universal Serial Bus (USB) security. The techniques include intercepting, by a Universal Serial Bus (USB) firewall of a USB device connected to a host, a file access request for a file. The techniques further include transmitting the file access request for the file to an authorization server, where the authorization server determines whether the file access request for the file is permitted based on a hash of the file. The techniques further include receiving a cryptographically signed message from the authorization server based on the hash of the file, where the cryptographically signed message indicates whether the file access request for the file is permitted.
