The release of thousands of pages of classified US government information over the weekend by whistleblower website Wikileaks prompted an order to all federal agencies by the White House Office of Management and Budget (OMB) to immediately review procedures in place for protecting sensitive data.
In a brief directive issued Sunday, OMB director Jacob Lew called on the heads of all federal agencies and departments to establish special security assessment teams to conduct the reviews. Each team should include counter-intelligence experts as well as security and information assurance experts, the directive noted.
Lew's memo requires that each agency evaluate their specific security measures for restricting access to classified government sysems.
The directive also orders agency heads to ensure that employees can only access data that's required for their jobs. As part of the review, agencies have been asked to implement restrictions on the availability and use of removable media on classified government networks.
The OMB and the Office of the Director of National Intelligence and the Information Security Oversight Office will assist agencies in reviewing security practices, the directive added.
Any failure by agencies to safeguard classified information "is unacceptable and will not be tolerated," the memo stated. "Any unauthorised disclosure of classified information is a violation of our law and compromises our national security."
The OMB directive does not offer specific deadlines for completing the reviews and implementing new procedures.
The OMB directive follows Wikileaks' release of tens of thousands of leaked US Department of State cables on Sunday.
The cables reveal sensitive and what government officials call potentially damaging information on US diplomatic activities in dozens of countries. The documents also revealed more data on the attacks against Google this year.
Wikileaks claims that it has a cache of more than 250,000 State Department cables, and plans to release them in batches over the next few months. The release of the initial set of documents yesterday provoked intense criticism from US officials as well as from governments around the world.
Peter King (R-NY), ranking member of the Committee on Homeland Security, yesterday called on Attorney General Eric Holder to label Wikileaks a terrorist organisation and to prosecute its founder, Julian Assange under the Espionage Act.
This is the second time this year that Wikileaks has released sensitive documents on such a massive scale.
In July, the site released close to 90,000 sensitive documents relating to the wars in Afghanistan and Iraq. That disclosure led Defense Secretary Robert Gates to order all military agencies to review their information security practices.
Bradley Manning, an Army intelligence analyst who has already been accused of supplying Wikileaks with a video allegedly showing a deadly US Apache helicopter attack in Iraq, is a prime suspect in the latest incident as well.
Bradley, who has been in solitary confinement for the past several months is alleged to have downloaded the documents and copied them onto removable thumb drives and rewritable CDs while stationed at a US Army base in Iraq.
