The Defense Information Systems Agency (DISA) is working to extend enterprise services to warfighters operating in
remote areas at the tactical edge of military communications and data networks, a senior official said at the Network Enabled Operations Conference
in Alexandria, Va., on Jan. 24.
To better provide services to the edges of the Defense
Department’s (DOD) networks, DISA is shifting its focus from an
enterprise-centric approach that pushed information out to the edge from data
centers located in the United States, said David Bennett, program executive
officer in charge of Global Information Grid enterprise services at DISA.
The new model is globally based, supporting disconnected, intermittent and low bandwidth
user environments by moving data from the edge to the core, he said.
Supporting users at the end of the last tactical mile
requires deployable enterprise services, Bennett said. These in-theater
services allow users to download applications locally, which is important for warfighters in disconnected or limited connectivity
To provide overall network integration that allows for more
seamless service, DISA is working on its Joint Command and Control architecture.
The architecture will ensure that information-sharing capabilities are built
into DOD service community strategies, Bennett said.
DISA is also working on new capabilities such as enterprise
messaging, which will be included in a deployable package designed to support
tactical users. The deployable enterprise services are a set of preconfigured
capabilities designed to provide warfighters with services and connectivity
from the edge to the core. These services are also configured to synchronize and
work with enterprise services when connectivity is available, he said.
Other DISA capabilities include enterprise services
management that can be customized to meet user requirements and enterprise
search, which is deployable on tactical enclave or ship hardware, Bennett said.
He said the search capability was created on Intelink, the intelligence
community’s information sharing network. This allows vetted users to search
both DOD and intelligence community databases.
DISA is also developing identity and access management
capabilities that can be used by DOD command and control systems and services.
One area focuses on attribute-based access control that allows administrators
to dynamically manage access control based on changing user roles and needs.
These capabilities provide for strong authentication and are traceable back to
the user, Bennett said.
In the near future, DISA is looking at a joint e-mail system that will
provide a single DOD enterprise with global email access and a global directory
service, Bennett said. The agency will also provide joint enterprise SharePoint
that will be globally accessible and access enterprise identity management
Another upcoming capability is joint enterprise file
sharing that will become available this year and consist of a network file
storage and sharing capability that can be accessed by DOD users in major
facilities or in forward operating posts, he said.
