A number of measures were introduced in an attempt to prevent and penalize activities that are deemed to support terrorism. It was made a crime to harbor or conceal terrorists, and those who do are subject to a fine or imprisonment of up to 10 years, or both. U.S. forfeiture law was also amended to allow authorities to seize all foreign and domestic assets from any group or individual that is caught planning to commit acts of terrorism against the U.S. or U.S. citizens.

However, should the offense occur a second time, the penalty increases up to 20 years' imprisonment. The act also specified the development and support of cybersecurity forensic capabilities. It directs the Attorney General to establish regional computer forensic laboratories that have the capability of performing
