System and method for providing network and computer firewall protection with dynamic address isolation to a device

A system comprising:

• a network interface configured to be coupled to an external network;
• a firewall in communication with the network interface, the firewall configured to perform both network-level security and application-level security on incoming data packets, the firewall being further configured to reject the incoming data packets if the incoming data packets include malicious content according to a security policy, the firewall being configured to allow the incoming data packets to pass to one or more applications if the incoming data packets do not include malicious content according to the security policy;
• a computer system in communication with the firewall, the computer system having one or more applications associated with at least one application address, the computer system being configured to send to the firewall outgoing data packets including an application identifier identifying a particular application of the one or more applications to the firewall;
• and
• an address translation engine configured to translate the at least one application address associated with the particular application of the one or more applications to an external address, thereby dynamically isolating the particular application of the one or more applications from the external network.
