Abstract:
1. A confidential information leakage prevention system which controls a first network access request sent from an application program via a network access service provision unit and a second network access request directly sent from an application program, based on a security level assigned to the application program, comprising: a first monitoring unit for monitoring whether the network access service provision unit has been called by the application program; a second monitoring unit for monitoring whether the second network access request is sent to a network; a first access control unit for controlling, when the first monitoring unit detects that the network access service provision unit has been called, the first network access request of the detected call, based on a security level assigned to the application program that has called the service provision unit; and a second access control unit for determining, when the second monitoring unit detects that the second network access request has been sent, whether the first access control unit has already performed access control on the detected second network access request, and, if the determination result is negative, controlling the second network access request based on a security level assigned to the application program that has sent the second network access request.
