Data mirroring method based on private head

Abstract

The invention discloses a data mirroring method based on a private HEAD, which includes: a user terminal accesses the Internet; an AH module identifies data packets for accessing the Internet, copies the data packets that meet the conditions, and adds a private HEAD to the front of the packet for encapsulation. Send the encapsulated data packet to the audit hardware module; both the HOST device and the audit hardware module have their own fixed network addresses; after the audit hardware module receives the encapsulated data packet, the AS module decapsulates it; audit The hardware module conducts a network security audit on the decapsulated data packets, discards useless data packets, converts useful data packets into data that meets the requirements and standards of public security in various cities, and reports to the designated audit server through the network. The present invention consumes less performance on the HOST equipment, has no impact on the user experience of the HOST equipment, reduces deployment costs, and is easier to implement in small and medium-sized places.
