Abstract
A system and method for monitoring a leakage of internal information by analyzing encrypted traffic according to the present invention is characterized in that an SSL session is not created directly between an internal computer and an external computer, but a monitoring computer creates SSL sessions with the internal computer and the external computer respectively, and when a data packet is transmitted from the internal computer to the external computer, the monitoring computer first checks whether the data packet contains internal information and then delivers the data packet.
