"In order to promote a united, Department-wide information-sharing environment, it is critical that each DHS component gives the highest priority to the sharing of potential terrorism, homeland security, law enforcement, and related information.' DHS personnel must have timely access to all relevant information they need to successfully perform their duties. Therefore, absent any legal prohibitions as set forth by the Department's General Counsel, information shall be shared within DHS whenever the requesting officer or employee has an authorized purpose for accessing the information in the performance of his or her duties: possesses the requisite security clearance, and assures adequate safeguarding and protection of the information. Furthermore, all DHS components are considered part of one 'agency' for purposes of the Privacy Act 5 U.S.C. 8 552a(a)(l), (b)(l). No DHS component should consider another DHS component to be a separate agency for information-sharing purposes."
