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

A system for secure copy-and-paste operations between hosts comprising:

• A plurality of hosts;
• and
• A secure copy-paste peripheral sharing device for supporting secure copy-paste operations between hosts,
• Each host is connected to the secure copy-paste peripheral sharing device and comprises copy-paste driver configured to fetch or store clipboard objects from the clipboard of the host
• The secure copy-paste peripheral sharing device, comprising:
• a plurality of copy-emulators and a plurality of paste emulators, configured each to be connected to one of the copy-paste drivers,
• a security bridge that is configured to securely pass clipboard objects between pairs of copy emulator and paste emulator,
• wherein the security bridge performs at least one of or any combination of:
• (1) enforce unidirectional data transfer of the clipboard object;
• (2) monitor the clipboard object and enable or disable the copy-paste operation according to a security policy or a set of security rules;
• (3) enable or disable the copy-paste operation according to security policy comprising from at least the identity of source host, the identity of the target host, the type of the clipboard object, time delays and time of day of the copy-paste operation;
• (4) modify the clipboard object to prevent sensitive data leakage;
• (5) build a profile of copy-paste operation patterns of users;
• (6) analyze clipboard object traffic to detect cybersecurity events;
• (7) log, audit and archive copy-paste operation or clipboard object traffic history;
• (8) scan virus existence in clipboard object;
• (9) sanitize or remove some information from clipboard objects;
• (8) encrypt and decrypt of clipboard objects;
• (9) lock suspicious peripheral sharing devices;
• and
• (10) prevent clipboard object transfer between pairs of copy-paste controllers according to security rules, and
• wherein 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 host's copy-paste driver.

A method for performing secure copy-and-paste operations between hosts through a peripheral sharing device that is attached to the hosts,

• the method comprising the steps of:
• receiving a clipboard object from a source host;
• transferring the clipboard to a security bridge;
• receiving the clipboard from the security bridge;
• and
• sending the clipboard to the target host,
• wherein the security bridge performs at least one of or any combination of:
• (1) enforcing unidirectional data transfer of the clipboard object;
• (2) monitoring the clipboard object and enabling or disabling the copy-paste operation according to a security policy or a set of security rules;
• (3) enabling or disabling the copy-paste operation according to security policy comprising from at least the identity of source host, the identity of the target host, the type of the clipboard object, time delays and time of day of the copy-paste operation;
• (4) modifying the clipboard object to prevent sensitive data leakage;
• (5) building a profile of copy-paste operation patterns of users;
• (6) analyzing clipboard object traffic to detect cyber-security events;
• (7) logging, auditing and archiving copy-paste operation or clipboard object traffic history;
• (8) scanning virus existence in clipboard object;
• (9) sanitizing or removing some information from clipboard objects;
• (8) encrypting and decrypting of clipboard objects;
• (9) locking suspicious peripheral sharing devices;
• and
• (10) preventing clipboard object transfer between pairs of copy-paste controller according to security rules.
