DISCONNECT THE COMPUTERS
All computers containing data or programs whose disclosure would compromise national security, individual privacy or infrastructure protection should be immediately disconnected from the Internet.
Access to those computers should be by hard-wired terminals exclusively.
Disconnecting the computers should thwart hackers who use the internet for unauthorized access to computer information.
Disconnecting should apply to all levels of government, government contractors, and public utilities.
People who need to work with information on the computers should do so from offices sufficiently close to the computers that a hard=wired connection can be implemented.
Organizations that need computers with Internet access can use separate computers that do not contain sensitive information and are not connected to the computers with the sensitive information.
There is no substitute for physical security.
