System and method of providing virus protection at a gateway

摘要

A system, a method for providing virus protection, and a computer program stored on a storage medium in a communication system including at least a first network coupled to a destination to which transmissions of data packets are made from the first network to the destination is described. A virus protection system includes a gateway, coupled between the first network and the destination, which includes a firewall which receives data packets and a virus scanning engine, coupled to the firewall, which receives the data packets after reception by the firewall, tests the data packets, passes any data packets, which are tested by the virus scanning engine to not contain a virus to the destination and discards any data packets which are tested by the virus scanning engine to contain a virus.

主权项

1. An apparatus comprising:
a hardware firewall configured to
receive a first data packet and a second data packet intended for a destination in networked communication with the hardware firewall;classify, responsive to a determination that the first data packet includes audio or video content, the first data packet as being a first type of data packet that cannot contain a virus;classify the second data packet as being a second type of data packet that can contain a virus;cause, responsive to classifying the first data packet as being the first type, transmission of the first data packet to the destination; andcause, responsive to classifying the second data packet as being the second type, transmission of the second data packet to a virus scanning engine for testing.
