Abstract
A method, system, and computer-usable medium are disclosed for: (i) determining if a server response from a server received at a security device and intended for a client includes original encryption key information for encrypting identifying information associated with the server; (ii) if the server response includes original encryption key information for encrypting identifying information associated with the server, determining if a network policy provides for decryption of identifying information associated with the server; and (iii) if the network policy provides for decryption of identifying information associated with the server, replacing the original encryption key information with modified encryption key information associated with the security device and communicating the server response to the client with the modified encryption key information associated with the security device.
