Despite calls from two senior House Democrats for the Homeland Security Department to stop work at least for a time on a new version of DHS’ national collaborative platform for sharing sensitive but unclassified information. an official who oversees the program’s development said its deployment should continue.

Stopping work now on the Homeland Security Information Network-Next Generation (HSIN Next Gen) project would hamper information sharing, said Harry McDavid, chief information officer for DHS’ Office of Operations Coordination which is developing the updated platform. McDavid said July 30 he was confident in the current plan for rolling out the new version of Homeland Security Information Network (HSIN) in phases over the next 12 to 18 months.

“Not continuing with [HSIN Next Gen] puts the successes that we’ve achieved at risk,” he said.

McDavid added that he isn’t the person who makes a decision whether to halt the program and that DHS was working to answer a series of questions and concerns that two senior House Democrats submitted to the department in a letter dated July 23.

Government auditors, DHS’ inspector general and lawmakers have criticized the first version of HSIN for not fully meeting its users’ needs. DHS hired General Dynamics for $62 million in May to work on the HSIN Next Gen project that DHS says will be easier to use and more secure.

McDavid said that the HSIN program office has developed a strategy for HSIN Next Gen that uses lessons learned, recognizes the resource limitations of the program and does not incur cost, schedule, performance or security risks.

McDavid made the comments at the Homeland Defense Journal’s Fusion Centers and Information Sharing Conference in Washington, where he discussed HSIN's use in fusion centers. State and local authorities at intelligence fusion centers around the country use HSIN to share information.

The 2008 National Response Framework (NRF), which delegates different emergency response tasks to federal, state and local governments as well as the private sector when re, also identified HSIN as “the primary reporting method for information flow.”
