U.S. lawmakers called on three large U.S. government agencies, including the Department of Energy, to start monitoring their IT purchases for possible malware, counterfeits or other security flaws, after a watchdog agency pointed out potential vulnerabilities in their IT supply-chain procedures.
The three agencies, also including the U.S. Department of Justice and Department of Homeland Security, do not have plans in place to identify possible embedded threats in IT products or monitor commercial IT products for embedded threats, said the U.S. Government Accountability Office, in a report released Tuesday.
With agencies buying hardware pieced together from components made all over the world, they need to check their purchases for vulnerabilities that could slip in at any point in the manufacturing and shipping process, Gregory Wilshusen, GAO's director of information security issues, told lawmakers.
"The global IT supply chain introduces risks that, if realized, could jeopardize the confidentiality, integrity and availability of federal information systems," he told the U.S. House of Representatives Energy and Commerce Committee's oversight subcommittee.
Of four national security-related agencies the GAO studies, only the Department of Defense has made significant progress toward identifying IT supply chain risks, despite an August 2009 standard on IT supply chain security published by the National Institute of Standards and Technology, the GAO said.
The GAO report prompted lawmakers to push Department of Energy CISO Gil Vega to develop an IT supply chain security plan. The DOE, which oversees the nation's nuclear energy stockpile, began to address the concerns in the GAO report this month, when it first heard of them, Vega told the subcommittee.
"When will the Department of Energy finish its process of giving guidance to your suppliers to promote their supply chain's integrity?" said Representative Cliff Stearns, a Florida Republican. "When is that date going to be?"
A date is "hard to predict," said Vega, who has been the agency's CISO for just eight months. Vega said he's not aware of any cyberattacks at the DOE that resulted from supply chain vulnerabilities.
Supply chain risks are real, Stearns said. Based on the DOE's nuclear mission, "I think you should have been ahead of the curve, instead of, just in the last two weeks, giving guidance to your suppliers," he said.
But four of the five witnesses at Tuesday's hearing, including Wilshusen, said vulnerabilities in the IT supply chain were not the most pressing cybersecurity concern for most federal agencies. Cyberattacks from outside groups or involving insiders are a bigger problem for agencies, said Dave Lounsbury, CTO at the Open Group, an IT standards consortium working on supply chain security.
Still, agencies need to address supply chain security, added Larry Castro, managing director of the Chertoff Group, a security consultancy. Castro pointed to China and Russia as countries that have the expertise to compromise the IT supply chain.
However, the GAO report suggested that merely looking at the country of origin of a piece of software or hardware may not be a good way to track possible supply-chain problems. U.S. intelligence agencies "offered the view that determining if a relationship exists between a supplier company and a foreign military or intelligence service is a more reliable indicator of a potential security risk than whether a product was manufactured or provisioned outside the United States," Casto said.
The U.S. government should investigate links between foreign IT suppliers and military and intelligence services in their countries, Castro recommended.
