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.
