David P. Pekoske, Senior Official Performing the Duties of the Deputy Secretary, of the Department of Homeland Security (DHS) signed the "NIEM first" memorandum on May 3rd, 2019 outlining the Department's adoption of the National Information Exchange Model (NIEM).
"The Information Sharing and Safeguarding Governance Board (ISSGB), has recommended to me, unanimously, that the Department adopt the National Information Exchange Model (NIEM) for all new data exchanges created by DHS operational components and Headquarters. While it would be inefficient to make all, existing data exchanges NIEM conformant, we can take steps to ensure NIEM conformance for all future data exchanges created at DHS. The adoption of NIEM for all new data exchanges will provide a critical foundation for future information sharing and exchange across the enterprise that best enables DHS to accomplish mission responsibilities while appropriately complying with information safeguards and privacy protections."
This memorandum, similar to DoD CIO's 2013 memo "Adoption of the National Information Exchange Model within the Department of Defense", amplifies the ongoing commitment by NIEM community executives to advance and champion greatest adoption of a common data standard to achieve data interoperability.
