The purpose of this legislation is to enhance oversight and transparency of the information systems and bulk data managed by the Office of Intelligence and Analysis within the Department of Homeland Security. It aims to ensure that these systems are regularly audited to maintain accountability and proper use of data. Key provisions of the law require the Under Secretary for Intelligence and Analysis to conduct an annual audit of the office's information systems and bulk data. This audit must be completed within 180 days of the law's enactment and annually thereafter.
