Abstract

See full text

A firewall system determines whether a protocol used by an incoming data packet is a standard protocol compliant with Request For Comment (RFC) standards. In the event the protocol is RFC compliant, the firewall transmits the packet to the recipient according to firewall policies regarding the standard protocol. If the protocol is not that of an RFC standard, the firewall determines whether the protocol matches an RFC-exception protocol in a RFC-exception protocol database. If the protocol does match an RFC-exception, the firewall may transmit the packet to the recipient according to firewall policies regarding the RFC-exception protocol. If it does not match an RFC-exception, the firewall may transmit the packet or protocol to a support system where it may be quarantined until it is approved based on a decision that the protocol is safe and/or widely adopted.
