Joint Regional Information Exchange System

Joint Regional Information Exchange System is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Joint Regional Information Exchange System rather than just read about it. In short: The Joint Regional Information Exchange System (JRIES) began in December 2002 as an all-source intelligence / information sharing system, designed initially as a grassroots pilot system to connect the California Anti-Terrorism Information Center, the New York Police Department, and the Defense Intelligence Agency (DIA).

Key takeaways

  • Joint Regional Information Exchange System belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Joint Regional Information Exchange System to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Joint Regional Information Exchange System from memory before moving on to harder problems.

Reference excerpt

The Joint Regional Information Exchange System (JRIES) began in December 2002 as an all-source intelligence / information sharing system, designed initially as a grassroots pilot system to connect the California Anti-Terrorism Information Center, the New York Police Department, and the Defense Intelligence Agency (DIA).

Purpose These groups designed JRIES, which was first deployed in February 2003, to facilitate the exchange of suspicious activity reports, register events potentially related to terrorist activity, and foster real-time intelligence and law enforcement collaboration in a secure environment across federal, state, and local jurisdictions. JRIES used a commercial, off-the-shelf software collaboration tool application to enable multiple groups to share the information securely. A JRIES executive board, composed of representatives from the participating groups, provided guidance and structure to help manage the system. JRIES proved useful during the northeast blackout in 2003 when information posted on the system allowed users across the country to quickly learn that the event was not related to terrorism. The system provided a very simple and efficient way for the law enforcement community to obtain situational awareness concurrently, without the need for hundreds of phone calls.

Transfer to DHS Although DIA originally operated and maintained JRIES, DIA transferred program management of the system to the U.S. Department of Homeland Security (DHS) in September 2003, due to funding constraints. DIA was concerned that managing JRIES to support domestic intelligence activities conflicted with its military intelligence role. As of February 2004, approximately 100 organizations–with more than 1,000 law enforcement and intelligence analysts from federal, state, and local government agencies—were using JRIES.

Expansion After acquiring JRIES, DHS recognized that the system's utility could be expanded beyond its existing counter-terrorism intelligence and threat awareness mission because JRIES met DHS' requirements for senior executive communications, crisis planning and management, and coordination and communications with first responder, emergency management, and military organizations. As such, in February 2004, DHS announced the expansion of JRIES as its primary communication, collaboration, situational awareness, and information-sharing system. The DHS Secretary renamed JRIES as the Homeland Security Information Network (HSIN) in order to reflect the system's broader scope. By December 2004, DHS had deployed HSIN to all 50 states, 53 major urban areas, five U.S. territories, the District of Columbia, and several international partners. DHS extended HSIN access beyond the law enforcement community to include state homeland security advisors, governors' offices, emergency managers, first responders, the National Guard, and an international component. DHS equipped each location with two laptops installed with the commercial, off-the-shelf software collaboration tool application.

Web-based portals In February 2004, because of the lack of scalability to accommodate a large increase in users, DHS decided to move HSIN away from the current software collaboration tool and to develop a series of web-based portals as replacements. Nonetheless, DHS continues to operate both the commercial software collaboration tool application and a portal to support the law enforcement community.

State and local initiatives DHS has expanded the role of HSIN through a state and local initiative. The goals of this initiative are to identify and address requirements of state and local communities of interest, as well as to provide robust training to promote effective use of the network. As of January 2006, eight states had deployed HSIN throughout their respective departments and agencies. Declaring HSIN the primary system for operational information sharing and collaboration, the DHS Secretary asked that the department's senior managers as well as headquarters and field personnel support the ongoing growth and utilization of HSIN.

Worked examples

Example 1 — a first encounter with Joint Regional Information Exchange System

Start with the simplest possible case. Write down what Joint Regional Information Exchange System claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Joint Regional Information Exchange System before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Joint Regional Information Exchange System ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Joint Regional Information Exchange System

In research
Joint Regional Information Exchange System appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Joint Regional Information Exchange System in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Joint Regional Information Exchange System is common in secondary-school and first-year university syllabi. It links to neighbouring topics Information systems, so understanding it makes those chapters shorter.
In everyday life
Look for Joint Regional Information Exchange System outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
