Abstract
A computer is especially vulnerable when connected to a network while software on the computer is in an unpatched state. A portable firewall adapter is installed inline between the computer having the unpatched software and a network. A firewall within the adapter enforces a security policy that protects the computer from attack via the network. The adapter allows the computer to be connected to the network in order to download patches and/or other software that cure the vulnerabilities on the computer.
