Abstract
A network firewall may apply policies to packets based on a security classification. Packets with an authenticated and established security connection may be handled at a high throughput while packets with unauthenticated connections may be handed at a low throughput or even discarded. In some embodiments, three or more levels of security classifications may be used to process packets at different speeds or priorities. In some embodiments, one device may classify and tag each packet, while another device within the network may process the packets according to the tags.
