WASHINGTON – After personnel data held by the Office of Personnel Management was compromised by hackers, the dispute over the improvement and possible reform of federal government’s cybersecurity system has become heated.
The OPM data breach resulted from a compromise of a highly privileged user’s credential, which also gave them access to the data center of the Department of Interior. Although no data was stolen from within DOI’s system, it triggered a large concern about the department’s computer network protection system.
According to the Federal Information Security Management Act, each deferral agency should develop, document and implement an agency-wide program to provide information security. But in reality, many federal agencies are using information protection services provided by other departments, such as DOI. The reason behind it is for economy purposes, according to Sylvia Burns, chief information officer of DOI. “You can gain economy from the scale. So it’s less expensive and more efficient for a customer to consume services from a provider like that.”
In 2005, OPM first became a customer of DOI’s data hosting service. DOI offers its IT infrastructure and host information, ensures the connection between DOI and OPM, and encrypts the connection between the two agencies.
“Shared service is a concept of creating a more robust, centralized point of service around specific activities,” Burns said, explaining the origin of this concept. According to Burns, a 2001 data breach in DOI resulted in disconnecting five DOI bureaus from the Internet for about six and half years. For the fear of being disconnected again, all the bureaus and offices in the department created separate protections for themselves. In that state, cooperation became hard because they were trying to protect themselves from being associated with trust data. In 2008, DOI reconnected those organizations back to Internet, and it turned out that they had difficulty just doing day-to-day work because of the security controls. That’s when the department began to create the segmented system.
Although this time’s data breach was not a result of technical failure, DOI hasn’t seriously treated the 3,000 critical vulnerabilities in its hundreds of publicly accessible computers that were identified by the Office of Inspector General. But viewing this issue from a broader perspective, OPM fell into a trap of an outdated model of cybersecurity system, which we call “line of sight governance.” This is a belief that I can walk down a corridor to where everybody is working and then I have the control of the security surrounding them. In the era of Internet when everyone is connected with the outside world, it’s just impossible to ensure their security by believing that internal system is absolutely secure.
The new model, called the BeyondCorp initiative, assumes that the internal network is as dangerous as the Internet. Using authentication, authorization and encryption, trust is moved from the network level to the device level. For example, Google staff are required to use a security key when connecting their computers to the Internet. When the security key is plugged into the USB portal, it automatically generates a one-time password. With this one-time password and the staff’s own username and password, the Internet is accessible.
“It’s relatively easy to get online in the company, but it can be very hard to access to the internal system when you are at home because a VPN is needed. And not everyone can get it unless you are at certain rank,” said Jiasong Sun, a Google employee. Some companies including Coca-Cola Co., Verizon Communications Inc. and Mazda Motor Corp. are taking a similar approach.
Several questions about DOI’s role in the breach remain unanswered, including whether or not other agencies may have been compromised, how many breaches took place at DOI and whether or not the attackers are still in the system. But this two factor authentication system is a possible solution that the DOI is considering to take after the data breach.
Rep. Will Hurd (R—TX) urges federal agencies and their CIOs to review past IG reports and address the vulnerabilities that have been identified. “We know what needs to be done, we just need to do it,” Hurd said.
