System and method for secure copy-and-paste operations between hosts through a peripheral sharing device

Abstract

A peripheral sharing device for supporting secure copy-paste operations between hosts comprising: a plurality of copy-emulators and a plurality of paste emulators, configured cach to be connected to a copy-paste driver, wherein cach copy-paste driver is running on one of a plurality of hosts that are connected to the peripheral sharing device, and the copy-paste driver is configured to fetch or store clipboard objects from the clipboard of the corresponding host, a security bridge that is configured to securely pass clipboard objects between pairs of copy emulator and paste emulator. The security bridge performs security operations, such as, enforce unidirectional data transfer of the clipboard object, monitor the clipboard object and enable or disable the copy-paste operation according to a set of security rules; enable or disable the copy-paste operation according to security policy, analyze clipboard object traffic to detect cybersecurity events, locking suspicious peripheral sharing devices, and preventing clipboard object transfer between pairs of copy-paste controllers according to security rules. The copy emulator receives the clipboard object from the copy-paste driver of a first host, transfer the clipboard object to the security bridge and conditioned upon passing the security conditions the security bridge transfer the clipboard object to the paste emulator that further pass the clipboard object to a second computer's copy-paste driver.
