IA Defense-in-Depth Implementation

To ensure a consistent "Defense-in-Depth" implementation across component systems of the GIG, IA architectural concepts must ultimately be translated into specific architecture guidance, IA standards and protocols, technical requirements, and policy. This applies to existing, emerging, and future system development efforts such as the Joint Tactical Radio System (JTRS), Warfighter Information Network-Tactical (WIN-T), GIG Bandwidth Expansion (GIG-BE), Intelligence Community System for Information Sharing (ICSIS), Transformational Communications (TC), and other programs supporting the GIG vision.

The implementation must allow both human users of the GIG, and automated services acting on behalf of GIG users, to access information and services from anywhere, based on need and capability. Information must be labeled and also cataloged using metadata, allowing users to search and retrieve the information required to fulfill their mission under a "smart-pull" and information management model. This requires the GIG to know where the information is posted and to recognize who the user is, regardless of location. System access will be available regardless of location; however, access to information will be restricted based on the threat inherent to that location. IA will enforce user privileges and access to the information in addition to providing mechanisms so that the information can be trusted as coming from its claimed source. These mechanisms also will ensure that information is unaltered during processing, storage, and transport. Ultimately, the GIG must enhance the capability to collect, process, and disseminate an uninterrupted flow of information-a Net-Centric approach-while inhibiting or denying an adversary's ability to do the same.
