US Initiative on Network Defense: Security Measures Against Cyber Threats

It will take several more years for the US government to fully install high-tech systems to block computer intrusions, a drawn-out timeline that enables criminals to become more adept at stealing sensitive data, experts say. As the Department of Homeland Security moves methodically to pare down and secure the approximately 2400 network connections used every day by millions of federal workers around the world, experts suggest that technology already may be passing them by.

The department that's responsible for securing government systems other than military sites is slowly moving all the government's Internet and e-mail traffic into secure networks that eventually will be guarded by intrusion detection and prevention programs. The networks are known as Einstein 2 and Einstein 3.
