Securing The Cyber Supply Chain

Many parties touch your organization's systems and software, potentially exposing them to malware, breaches, or worse. A new end-to-end approach is required to minimize the risks.

Total Trust

One way that DOD and the National Security Agency are tackling this issue already is by commissioning custom chipsets for some of their most critical systems. Only a few chipmakers, like Intel, still manufacture their chips in their entirety. Most are now fabless, and in the process, they've given up a measure of security, something the military and intelligence communities can't accept for their most critical systems. "Maliciously tampered integrated circuits cannot be patched," retired Army Gen. Wesley Clark recently wrote in Foreign Affairs magazine. "They are the ultimate sleeper cell."

The Defense Department requires chips used in critical systems to be built by and procured from trusted companies and facilities within the continental United States. In 2003, NSA joined with DOD to create the Trusted Access Program Office, also known as Trusted Foundry. That program enables DOD and NSA to track their chips through the supply chain from design to delivery.

The National Security Agency and the Defense Department have a 10-year contract with IBM through 2013 and work with other manufacturers that build components at more than a dozen factories in the United States. In fiscal 2008, the Trusted Foundry program delivered more than 21,000 parts and 340 chipset designs for more than 70 DOD and NSA programs and contracts, according to budget documents.

The agencies plan to spend about $41 million this year to develop custom chips. Last year, NSA spent about $13 million just to form partnerships and to accredit suppliers.

In fiscal 2010, the agencies plan to redouble their Trusted Foundry efforts, developing new sources across the supply chain, according to budget documents. Under a Congressional requirement in this year's defense budget, DOD is to team up with the intelligence community, private industry, and academia to assess ways to verify the authenticity and "trust" of chips that the Defense Department buys from commercial sources.

The Defense Advanced Research Projects Agency is in the middle of a $19 million, three-year program called Trust in Integrated Circuits that tries to determine ways to quickly verify that chips are built to carry out only the functions for which they're intended. The agency employed MIT engineers to compromise chips, and three companies to develop and test new ways to sort the compromised chips from real ones.

As the evidence shows, the IT risks and vulnerabilities in an improperly managed supply chain, from counterfeit equipment to malware to other avenues of attack, are real and growing. It may be unrealistic to lock down your organization's IT supply chain from end to end, but IT pros can't afford to ignore the issue. IT departments must keep a more watchful eye on vendors, partners, and others in their cyber supply chains and adopt best practices for mitigating risks across their systems and processes.

Enterprise Vulnerabilities
From DHS/US-CERT's National Vulnerability Database
CVE-2014-0607
Published: 2014-07-24
Unrestricted file upload vulnerability in Attachmate Verastream Process Designer (VPD) before R6 SP1 Hotfix 1 allows remote attackers to execute arbitrary code by uploading and launching an executable file.

CVE-2014-1419
Published: 2014-07-24
Race condition in the power policy functions in policy-funcs in acpi-support before 0.142 allows local users to gain privileges via unspecified vectors.

CVE-2014-2360
Published: 2014-07-24
OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules allow remote attackers to execute arbitrary code via packets that report a high battery voltage.

CVE-2014-2361
Published: 2014-07-24
OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules, when BreeZ is used, do not require authentication for reading the site security key, which allows physically proximate attackers to spoof communication by obtaining this key after use of direct hardware access or manual-setup mode.

CVE-2014-2362
Published: 2014-07-24
OleumTech WIO DH2 Wireless Gateway and Sensor Wireless I/O Modules rely exclusively on a time value for entropy in key generation, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by predicting the time of project creation.
