Application Level Gateway Benefits

The application level gateway offers the following benefits.

• It provides the same filtering benefits of the packet filtering firewall.
• The gateway can prevent application level attacks as previously discussed.
• It completely hides the protected network from the Internet.
• The application level gateway can provide complete logging of all traffic in and out of the firewall. This leaves a record of any attempted or successful break-ins to the protected network. Without logging it is difficult to tell when someone has broken in or is attempting to break in to the network.
