Cyber security is becoming a large concern throughout the world, as governments face repeated onslaughts against their IT infrastructure.

According to the Wall Street Journal, U.S. military and civilian systems are challenged thousands of times daily. The North Atlantic Treaty Organization faces approximately 100 attacks every day at its headquarters. Similarly, the U.S. government believes at least 100 nations are persistently attempting to break into its networks.

In response, the Pentagon will be unleashing a Cyber Command center to protect itself and other government agencies against electronic infiltration.

While the Pentagon's cyber security system is ahead of much of the rest of the world, there are still legal issues preventing the government from complete security.

As things stand, the government is not legally allowed to provide cyber protection for private citizens or institutions. This leaves banks, centers of industry and major businesses somewhat vulnerable, as other nations may attack them in an effort to get to the government. Discussions have already begun to update legislation to mandate an increased level of national cyber security.

National security can be threatened if the government is unable to protect its business and industry. Iran is currently working to fend of a virus dubbed Stuxnet that could have caused catastrophic damage in the nation. Stuxnet was launched, presumably by another country, at Iran's industrial systems. If the virus had gotten through to the critical areas of the network, it could have disrupted, sabotaged or controlled factories for extended periods of time.
