Patent attributes
Systems and methods for centralized management and enforcement of online privacy policies of a private network are provided. According to one embodiment, existence of private information contained in a data packet originated by a client device of a private network and destined for a server device external to the private network is identified by a network security device protecting the private network by scanning the data packet for information matching a signature contained within a private information signature database. An online privacy policy of the private network is determined by the network security device that is applicable to the private information with reference to a privacy policy set defined by an administrator of the private network. The online privacy policy is enforced by the network security device on the data packet by performing one or more actions specified by the online privacy policy to the data packet.
