We determined that DHS needs to improve the collection and management of data across its multiple components to better serve and safeguard the public.  The data access, availability, accuracy, completeness, and relevance issues we identified presented numerous obstacles for DHS personnel who did not have essential information they needed for decision making or to effectively and efficiently carry out day-to-day mission operations.  Although DHS has improved its information security program and developed plans to improve quality and management of its data, follow through and continued improvement will be essential to address the internal control issues underlying the data deficiencies highlighted in the report.  We made no recommendations in the summary report.
