ABSTRACT:
Methods and systems for distinguishing between sources of messages at a computer system resource are provided. In particular, messages are classified according to the physical interface at which the messages are received. A message received at an interface connected to a trusted source has the port address associated with that message mapped to a predefined port address by a firewall computer, before being passed to a server computer or other system resource. A message received at an interface that is connected to an untrusted source is passed to the server computer using the original port address. The server computer may then treat messages associated with one of the reserved port addresses differently from messages associated with a non-reserved port address.
