We present a new security technology called the Multilayer Firewall. We argue that it is useful in some situations for which other approaches, such as cryptographically protected communications, present operational or economic difficulties. In other circumstances a Multilayer Firewall can compliment such security technology by providing additional protection against intruder attacks. We first present the operational theory behind the Multilayer Firewall and then describe a prototype that we designed and implemented.
