Everyone talks about weirdo, geek computer hackers who break into heavily protected bank or military computer systems. But imagine using hacker skills for military purposes. For instance, imagine the military value of taking an enemy’s command-and-control system, and inserting a depiction of forces you want him to see, instead of the real-world situation. How about entering his air defense system and letting him “see” false attacks to the west, while your real attack comes from the east? Why not lead him to believe that your ground forces are located where they are not, so he will exhaust his artillery ammunition pounding barren land, while your force escapes unharmed? Or even make him believe the forces arrayed against him are so vast and dominating that he will sue for peace before the battle begins?

Information warfare can be conducted at all levels of conflict, and includes a defensive side as well.

Of all the nations of the world, the United States is the most vulnerable to computer attacks. We use computers everywhere. Our telephones are now simple computer entry pads. Our wristwatches are computers. We plan our days, operate our automobiles, and communicate with computers. Our military equipment is so advanced largely because computers aim our guns, fly our planes, and operate our ships.

Therefore, even as we do our best to control the inputs to an enemy’s computers and knowledge system, we must also protect the integrity of the knowledge systems we are using to prosecute the battle.

Most easily understood is the need to protect our own computer databases from corruption or other manipulation. Though private industry and the military have been working this problem for years, the threat has grown at a pace equal only to the raging change in computer capabilities worldwide. There are no longer “have” and “have not” nations when it comes to the capacity to access and manipulate computer databases and programs.

Meanwhile, most current users are in a state of denial about the vulnerability of their data systems, simply because they have some small protection—and the alternative is too terrible to contemplate.

For example, the banking industry loses millions of dollars each year to computer crime. They can afford to overlook that loss. But what if computer criminals learned how to attack the customer trust and confidence on which their industry is built and relies? Could they afford to overlook that? Other financial markets, such as stock exchanges, suffer the same vulnerability.
