  • NCDI is a merge of a grass roots effortand CNCI
  • Current goal of NCDI: Create an actionable R&D plan
  • Summary of NCDI planning meetings
  • Why it is a daunting (but achievable) challenge to realize a secure system

House panel chief demands details of cybersecurity plan (October 24, 2007)

The chairman of the House Homeland Security Committee called on the Bush administration yesterday to delay the planned launch of a multi- billion-dollar cybersecurity initiative so that Congress could have time to evaluate it. Rep. Bennie Thompsonsaid he wants to make sure the new program is legal before it is launched. In an interview, the Mississippi Democrat said he had been told that President Bush might unveil the initiative as early as next week. Known internally as the"Cyber Initiative,"the program is designed to use the spying capabilities of the National Security Agency and other agencies to protect government and private communications networks from infiltration by terrorists and hackers. The Sun reported the existence of the program last month, but Thompson said the administration has refused to discuss the initiative with members of his committee, despite repeated requests.
a letter this week to Homeland Security Secretary Michael Chertoff, Thompson demanded that his committee receive a briefing on details of the plan. He also warned that the "centralization of power" envisioned under the initiative raised "significant questions" that should be answered before the program is launched. Thompson - whose panel oversees the Homeland Security Department, which would run the initiative - said he was unaware of the program's existence until I …

A Homeland Security spokeswoman said Chertoff had received Thompson's letter, which was dated Monday, and would respond "in a timely fashion. We do agree that cybersecurity is a very important issue, and that is why since the beginning of this congressional session DHS has provided more than a half a dozen briefings to the House Homeland Security Committee on cyberthreats and related issues," said the spokeswoman, Laura Keehner.Thompson said that if the administration continues to give his panel the silent treatment, he will consider issuing a congressional subpoena. "You have to put sunshine on a program so sensitive as this," he said. The administration is saying that "'you have to believe us.' Obviously, as a nation of laws, we can't accept that.“ Thompson said that because the program involves the NSA and similar agencies, questions aboutprivacyand domestic surveillance would be of particular concern.

findings of ncdi
Findings of NCDI
  • “Attackers Rule !” and Disasters are Likely
  • Short-term Measures Essential but Insufficient
  • Market Forces Will Not Change the Balance
  • Usability & Manageability Critical to Solution
  • New Technology Can Catalyze Major Changes
  • Research Business as Usual will Not Work

Only a National Initiative Involving Researchers, Industry with Government Funding Will Make a Real Difference

ncdi vision
NCDI Vision

Over the next ten years transform the cyber-infrastructure to be resistant to attack so that critical national interests are protected from catastrophic damage and our society can confidently adopt new technological advances

Transformation means we must learn how to build the new infrastructure and deploy it. Learning how to execute this transformation will advance both technology and U.S. competitiveness in many ways
