Abstract

The invention discloses antivirus method and system for a secure gateway cluster. in the method, the secure gateway cluster selects one of a plurality of secure gateway devices in advance as a main secure gateway, and the other secure gateway devices are used as backup secure gateways; the main secure gateway identifies a data stream needing antivirus processing and sends the data stream needing antivirus processing to the backup secure gateways through inquiring a cluster state database and a predetermined load balancing strategy; the backup secure gateways carry out antivirus processing on the received data stream needing antivirus processing, package and send the processed data stream to the main secure gateway; and the main secure gateway de-package and forward a data packet subjected to antivirus processing. In the invention, the unification of the transparency and the high performance of the secure gateway cluster is realized, and the utilization ratio of overall resources of the secure gateway cluster is improved on the basis of maintaining high availability of the secure gateway cluster through an effective dynamic load balancing mechanism.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a security gateway cluster antivirus method and system. Background technique [0002] With the continuous development of network technology and network security technology, the traditional security gateway function can no longer meet the emerging various new needs. Traditional security gateways only perform centralized access control at the network layer, and are powerless to the security of the application layer. The new generation of security gateways also need to perform centralized control of the security of the application layer, so as to realize the three-dimensional security control of the network from the second layer to the seventh layer. In the emerging application layer security functions, the anti-virus function plays a very important role. The security gateway needs to perform real-time virus scanning on the FTP, HTTP, POP3, SMTP, IMAP and other traffic pass...
