Law enforcement information sharing has expanded significantly across all levels of government, improving law enforcement's ability to detect, prevent, and respond to acts of terrorism. The sharing of law enforcement information is not a single integrated process. Rather, it cuts across business processes in multiple communities and at all levels of government. But these seemingly unrelated efforts share many features in common.

UCORE is a federal information sharing initiative that supports the NSIS and associated agency strategies. UCORE enables information sharing by defining an implementable specification (XML Schema) containing agreed-upon representations for the most commonly shared and universally understood concepts of who, what, when, and where in the context of national security.

In 2010, the Department of Homeland Security (DHS) conducted the first nationwide, in-depth assessment of fusion center baseline capabilities. The baseline capabilities assessment has advanced DHS’s responsibility to bring together multiple federal agencies and representatives of state, local, tribal, and territorial governments to establish effective, efficient, and coordinated federal support to designated state and major urban area fusion centers.

In 2008, the Seahawk project in Charleston, South Carolina, operating under the umbrella of the Maritime Domain Awareness (MDA) initiative, generated a Vessel Activity Report (VAR) for each vessel inbound to the Port of Charleston. Using the Maritime Information Exchange Model (MIEM)—which would soon become NIEM-Maritime—the Department of Transportation, the Coast Guard, the Navy, and 30 other participating federal, state, and local agencies could all exchange information about cargos, crews, and vessels. The Seahawk platform generated a VAR for each vessel, adding value with a risk assessment, vessel analyses, and related data. 

Alerts, warnings, and notifications are produced by agencies at all levels of government and serve a variety of mission and organizational needs. AWNs are a form of communication that enables authorities to share information about threats, events, and incidents with stakeholders for preparedness, mitigation, response, and recovery. Currently there are multiple government AWN protocols and methods and mechanisms for dissemination through a wide array of distribution channels between federal, state, local, tribal, and territorial governments.

The ISE Architecture Program describes the necessary rules and practices to plan and operate ISE participant systems in a way that is consistent with enterprise architecture best practices. This program helps partner agencies across broad mission areas such as maritime, cargo, aviation, cybersecurity, and healthcare identify the necessary interoperability requirements for responsible information sharing.

The Intelligence Reform and Terrorism Prevention Act of 2004, as amended, requires implementation of an ISE Architecture to facilitate information sharing.
