Global Information Grid

Global Information Grid is a computer 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 Global Information Grid rather than just read about it. In short: The Global Information Grid (GIG), now referred to as the Department of Defense Information Network (DODIN), refers to the entire network of information transmission and processing capabilities maintained by the United States Department of Defense (DoD). It is a worldwide network of information transmission, of associated processes, and of personnel serving to collect, process, safeguard, transmit, and manage this i…

Key takeaways

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

Reference excerpt

The Global Information Grid (GIG), now referred to as the Department of Defense Information Network (DODIN), refers to the entire network of information transmission and processing capabilities maintained by the United States Department of Defense (DoD). It is a worldwide network of information transmission, of associated processes, and of personnel serving to collect, process, safeguard, transmit, and manage this information. It is an all-encompassing communications project of the Department of Defense. The GIG makes this immediately available to military personnel, to those responsible for military politics, and for support personnel. It includes all infrastructure, bought or loaned, of communications, electronics, informatics (including software and databases), and security. It is the most visible manifestation of network-centric warfare. It is the combination of technology and human activity that enables warfighters to access information on demand. It is defined as a "globally interconnected, end-to-end set of information capabilities for collecting, processing, storing, disseminating, and managing information on demand to warfighters, policy makers, and support personnel". The GIG includes owned and leased communications and computing systems and services, software (including applications), data, security services, other associated services, and National Security Systems. Non-GIG information technology (IT) includes stand-alone, self-contained, or embedded IT that is not, and will not be, connected to the enterprise network. This new definition removes references to the National Security Systems as defined in section 5142 of the Clinger-Cohen Act of 1996. Further, this new definition removes the references to the GIG providing capabilities from all operating locations (bases, posts, camps, stations, facilities, mobile platforms, and deployed sites). And lastly, this definition removes the part of the definition that discusses the interfaces to coalition, allied, and non-Department of Defense users and systems. The DoD's use of the term "GIG" is undergoing changes as the Department deals with new concepts such as Cyberspace Operations, GIG 2.0 (A Joint Staff J6 Initiative), and the Department of Defense Information Enterprise (DIE). The GIG is managed by a construct known as NetOps. NetOps is defined as the operational framework consisting of three essential tasks, Situational Awareness (SA), and Command & Control (C2) that the Commander (CDR) of United States Strategic Command (USSTRATCOM), in coordination with DoD and Global NetOps Community, employs to operate and defend the GIG to ensure information superiority.

In the past The specifications for the GIG were published by the DoD on 22 September 1999, and the assistant secretary of defense officially mandated it on 19 September 2002 to carry out the project. Although in 2008, the ambitious objectives of the program had not been realized, informatic communications between soldiers and commanders on the battlefield had been successfully realized, the most well-known examples having occurred during the 2003 invasion of Iraq. The GIG underwent a severe cyberattack in 2008, in the form of a computer virus which spread through military computer networks. As a result, the US Strategic Command banned all forms of removable media, including thumb drives, DVDs, and floppy disks. At the time, the GIG contained about 17 million military computers, and it was scanned millions of times daily.

Defense Information Enterprise The Department of Defense Information Enterprise is defined as the DoD information resources, assets, and processes required to achieve an information advantage and share information across the Department of Defense and with mission partners. It includes:

the information itself and the Department's management over the information life cycle the processes, including risk management, associated with managing information to accomplish the DoD mission and functions activities related to designing, building, populating, acquiring, managing, operating, protecting, and defending the information enterprise related information resources such as personnel, funds, equipment, and IT, including national security systems

Vision The Network-Centric Warfare (NCW) doctrine represents a fundamental shift in military culture, away from compartmentalized war machines and toward interconnected units operating cohesively. The tenets of Network Centric Warfare are:

A robustly networked force improves information sharing; Information sharing enhances the quality of information and shared situational awareness; Shared situational awareness enables collaboration and self-synchronization and enhances sustainability and speed of command; Speed of command, in turn, dramatically increases mission effectiveness. At the enterprise level, forging new paths with whom components of the military communicate will ease logistics burdens, improve communication and combat effectiveness of the war fighter, decrease instances of confusion-related fratricide, accelerate the trend in minimizing collateral damage, and hasten the flow of business. For the warfighter, situational awareness would be improved tremendously by linking what he sees with what an overhead satellite sees. The fog of war would be lifted by seamless communication between unit members, off site detection devices, and commanders operating behind the line. Improved coordination may also assist in delivering appropriate firepower or other tangible assets to first responders during domestic attacks and natural disasters worldwide.

Worked examples

Example 1 — a first encounter with Global Information Grid

Start with the simplest possible case. Write down what Global Information Grid claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 Global Information Grid 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 Global Information Grid 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 Global Information Grid

In research
Global Information Grid appears in computer 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 Global Information Grid 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
Global Information Grid is common in secondary-school and first-year university syllabi. It links to neighbouring topics 21st-century conflicts, Grid computing, Military communications, so understanding it makes those chapters shorter.
In everyday life
Look for Global Information Grid 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.
