GCN : February 2015
[BrieFing] 14 GCN FEBRUARY 2015 • GCN.COM The Office of the Director of National Intelligence’s Information Sharing Environment released what it called the first-ever roadmap for national secu- rity information sharing, a set of best practices for agencies and IT firms to synchronize data sharing in pursuing national security threats. The model, called the Data Aggrega- tion Reference Architecture (DARA), was developed over several years as a com- pendium of ways for agencies to share aggregate information to gain insights into potentially relevant intelligence data, said government executives involved the effort. “The mission is improving the sharing and safeguarding of information across the whole of government,” said Kshe- mendra Paul, program manager of the Information Sharing Environment, in a recent video statement. The Information Sharing Environment refers to the people, projects and agen- cies that enable information national security data sharing. DARA would provide a reference architecture or model to the groups to blend their information sharing systems and practices. It addresses how to “pull data sets together in a way that protects information security and protects the privacy of individuals who might be rep- resented in that information,” said Paul. The payoffs for agencies and teams using the plan include access to new analytics tools and access to data from other agencies in the national security establishment. “When analysts are able to search correlated data that other agencies pro- vide using the DARA framework, then organizations do not need to replicate information between systems, which saves storage space, bandwidth and technical staff time across the entire federal enterprise,” according to the DARA plan. The document is also aimed at the national security establishment’s indus- try partners, said Paul, to help them by laying out the roadmap for programs where they will be selling products and services. Ultimately, DARA is a model for how agencies and firms can link pertinent information across rapidly circulating data streams. Managers of the program said the big data insights produced by the DARA roadmap will save lives. The Senate Select Committee on Intelligence, for instance, reported that seven of the 14 separate intelligence failures that led to the Christmas 2009 “shoe bomber” incident were “directly related to limits in data interoperability, aggregation and correlation,” according to a blog post last month by Michael Kennedy, PM-ISE Executive for Assured Interoperability. “We recognize that harmonizing the entire federal government and mandat- ing standards cannot happen over- night,” Kennedy said, “but the DARA takes an important step in that direction, by establishing consistency in under- standing the issues involved, organiza- tional expectations and terminology. Paul emphasized two key features of DARA, starting with its importance as a basic guide to interoperability. “When you talk about big data analytics, the big dirty secret is the prosaic issues of data plumbing: moving data sets, cleansing data, the basic extraction, movement and loading of information,” he said. “What becomes a core issue is that different agencies, different trading part- ners, do it differently and that adds a lot of friction, adds a lot of point-to-point connections.” The second take-away from develop- ing the new reference architecture is its maturity model approach. “Not every agency, not every pro- gram is in the same place in terms of their data management approach,” said Paul, including “their readiness to share information, to assure policy around security and to show agencies where they are on the continuum of maturity.” The roadmap will help them get better in the future, he said. Paul encouraged agencies to down- load the DARA and use it to provide feedback. “Let us know where you have had successes and where there’s more work we can do to make the guidance that much more useful to you and your program,” he said. • Agencies get roadmap for security data sharing • Define the interoperability require- ments for data aggregation enterprise investments. • Define a reference architecture that enables entity resolution, data correla- tion and disambiguation across multiple federal databases. • Provide directions to identify what in- dividual agencies need to do to embrace a federated approach and assess the possible organizational impacts. • Specify what individual agencies need to do to embrace a federated approach and possible enhancements to their investments. • Serve as a broad, general reference architecture that guides the creation of more specific, concrete solution archi- tectures. 5 goals of the Data Aggregation Reference Architecture 0215gcn_005-016.indd 14 2/3/15 9:31 AM
