NATIONAL INFORMATION EXCHANGE MODEL

Mission

The CBRN domain provides the primary source of data elements and attributes for the N.25 Information Exchange Package (IEP) as well as a source of standard components for other IEPs when there is a need for data components that have been defined in the CBRN domain.


Governance

CBRN is governed by the CBRN Domain Community of Interest (COI) and is currently under the stewardship of DHS Domestic Nuclear Detection Office (DNDO).  To support the need for information-sharing in the Preventive Rad/Nuc Detection mission area, DHS's DNDO, with the support and cooperation of Customs and Border Patrol (CBP), developed a standard messaging protocol for interoperability and information sharing among Global Nuclear Detection Architecture (GNDA) participants – the N.25 Protocol. During the development of the N.25 Protocol, the CBRN domain was established to publish a set of data elements and common Rad/Nuc vocabulary that did not already exist in the model. Subsequently, these domain elements were harmonized with the Maritime and International Trade domains.
