Subtitle B legislated for the creation of a secure network which can be used by financial institutions to report suspicious transactions and which can also give them alerts of relevant suspicious activities. Subtitle B also makes FinCEN a bureau of the United States Department of Treasury. The subtitle allows the Board of Governors of the Federal Reserve System to authorize personnel to act as law enforcement officers to protect the premises, grounds, property and personnel of any U.S. Federal reserve bank, and allows them to delegate this authority to U.S. Federal Reserve Banks. It instructs any United States Executive Directors of international financial institutions to use their voice and vote to support any country that has taken action to support the U.S.'s War on Terrorism, and to require such Executive Directors to provide ongoing auditing of disbursements made from their institutions to ensure that no funds are paid to persons who commit, threaten to commit, or support terrorism.
