Testimony to the U.S. House of
Representatives
Committee on Veterans Affairs
Information Security at the Department of Veterans Affairs
Dennis Hoffman
Vice President of Information Security
EMC Corporation
May 25, 2006
Mr. Chairman, thank you for the
opportunity to testify before the House Committee on Veterans Affairs.
EMC is the world’s leading provider of technology that allows
organizations of all sizes to store, manage, protect, and secure their
most critical asset: their information. We invest more than $1 billion
annually ($1.2 billion this year) in research and development to
innovate technology solutions that allow enterprises to manage, store,
protect, and secure their growing volumes of information; from its
creation, to its ultimate disposal, helping them efficiently, and
securely, gain the maximum value from their information throughout its
lifecycle.
I am Dennis Hoffman, Vice President of Information Security at EMC
Corporation. Data breaches are happening at an alarming rate. Last year,
at least 23 million—or about one in nine—Americans received notification
of a data security breach.1 The Department of Veterans Affairs is not
alone. Organizations—from government entities to commercial
enterprises—all face this problem. Despite the media’s focus on breaches
involving personal information, the problem is not limited to this type
of information. Organizations create many types of sensitive or mission
critical information; many government agencies’ and commercial
businesses’ primary product is information, which they cannot afford to
be compromised.
Despite massive investments in security technologies, few organizations
today in the private sector feel their data are secure because the
majority of today’s security solutions protect networks, data centers,
and resources, but not information itself. The historic threat of
external hackers has driven IT professionals to take a “perimeter
security” approach to securing sensitive information.
The fundamental issue with this approach is that while these are
necessary investments, they are not complete and do not solve the
problem. Commercial enterprises spent more than $6 billion on security
software last year.2 Despite that investment, 82 percent of commercial
enterprises do not feel their data are secure or “adequately
protected”.3
Even though the nature of security threats is changing, the majority of
enterprise data security spending is still “perimeter-centric”—aiming to
protect the network perimeter from outside threats. Two-thirds of
hardware and software spending last year was on perimeter-focused
technologies such as firewalls, virtual private networks, intrusion
protection systems, antivirus, and anti-malware.4
The problem, however, is that none of these technologies protects data;
they protect the IT infrastructure. None would have prevented the
compromise of veterans’ data from this breach. For example, if a laptop
or similar device were stolen, it is likely the laptop would have some
sort of antivirus software—the largest security software market
today—installed. However, this software would do nothing to protect the
sensitive information stored on the laptop. Technology exists today,
which is used by the National Security oversight committees in The
Congress that would render specific information on the laptop unusable.
Erecting perimeters ignores the fact that in order to have value,
information moves throughout or between organizations. Once your
information moves (accessed, downloaded, e-mailed, printed, etc.)
outside secure perimeters, it is left unprotected.
Additionally, a perimeter security approach ignores the fact that often
the threat exists inside the perimeter. A comprehensive approach is
needed that secures the information, as well as the IT infrastructure.
Thus, information security has increasingly become an information
management issue.
IT professionals are realizing that the internal threat is the more
detrimental. 70 percent of security incidents that cause monetary loss
to enterprises involve insiders.5 The internal threat may be
malicious—such as a criminal stealing credit card data, or it may very
well be inadvertent—a human resources worker e-mailing sensitive
employee health data outside the company by accident. Internal threats
are magnified by the fact that we are an increasingly mobile workforce.
Today, nearly a quarter of the world’s online workforce works
“remotely”. Given that workers take their laptops (often containing
sensitive material) to work and home again, it is only a matter of time
before sensitive data become exposed.
Threats today come from both likely and unlikely sources. While it is
necessary to defend against sophisticated hackers who are deft at
exploiting vulnerabilities in a system, it is equally important to
understand the inherent danger from traditional threats. Media accounts
of the data loss at the VA state that the individual responsible was
likely not part of an elaborate scheme to steal millions of Social
Security numbers, but rather, was the victim of a simple burglary.
However, with no security attributable to the data on the laptop, the
possibility for fraud becomes a high value alternative to just selling
the device.
This event speaks to a wider information security problem. Organizations
often 1) cannot distinguish whether data are sensitive or not, 2) do not
know where their sensitive data reside, 3) do not enforce security
policies around those sensitive data, and 4) are not able to prove
compliance with those policies.
In this breach, the data in question may have been exported from a
database. While the database itself was probably “locked down” with all
of the appropriate access controls, once the names and Social Security
numbers are exported into a file, the controls associated with the
database become irrelevant. An Excel spreadsheet, for example, could be
stored or moved anywhere: on an insecure file share, employee laptop, or
e-mailed outside of the organization. Sensitive data such as these often
propagate throughout (and beyond) a network as they are saved,
replicated, accessed, e-mailed, manipulated, and resaved. Moreover, as
the file moves and is saved in various locations, the organization has
no knowledge of what information is contained therein, and whether it is
sensitive.
While the VA has a security policy that forbids sensitive data from
leaving the premises, the policy was unenforceable. Similarly, many
commercial organizations have reams of paper-based business and security
policies that rarely see the light of day. Not only are they rarely
enforced in some automated fashion, but they are often not effectively
communicated to an organization’s employee base.
Finally, many organizations do not have a way to prove compliance with
the policies they have established. This is detrimental for two reasons:
1) policy violations are not detectable in real time to enable
corrective action; and 2) they are not able to demonstrate (to internal
or external auditors) the effectiveness of the security in place.
Thus, how do we solve the problem of protecting data as opposed to
protecting the IT infrastructure? The solution to this problem lies in
people, processes, and technology, where technology is actually the
minor piece. It is important to note that there is no single threaded
solution or technology “silver bullet”, and to prescribe one would be a
mistake.
There must be a fundamental shift in our approach to information
security. The focus—rather than being “perimeter” or “network” centric,
should be “information” centric. It should aim to secure data
themselves. To accomplish this, organizations must start by assessing
the security of their data. They must understand and define what
constitutes sensitive data, where those data reside, and how those data
are being used.
Second, organizations should create policies for the storage, access,
and use of those sensitive data. The organization is then able to employ
the appropriate mechanisms to enforce those policies at the data level
by leveraging technologies that enable “Data Element Rights Management,”
which grants or denies access and use privileges (who can see it, when
it can be seen, where it can be seen, if it can be copied, printed,
forwarded, and when access should be revoked or expired) based on the
policy assigned to the specific data. Thus, the sensitive data are
protected at the point of access, whether that is inside the office on
the corporate network or on a laptop at home.
Finally, organizations should be able to enforce and prove that they are
in compliance with those policies at any time by leveraging automated
technologies that provide an audit trail of authorized data access, or
attempted unauthorized data access. This has the dual effect of enabling
organizations to detect policy violations on a real-time basis for
remediation purposes, as well as to prove that the security they have in
place is effective.
Information security need not be the equivalent of boiling the ocean.
Within the majority of Federal agencies, the IT infrastructure that
supports the enterprise is often highly decentralized and stove-piped.
The VA has more than twenty-five separate data centers, which
historically have operated under various levels of decentralized
management and control. With this degree of decentralization and
disparate IT systems, our experience indicates that any comprehensive
approach to data security methodology or technology will be exceedingly
difficult to effectively implement.
Mr. Chairman, you have been at the forefront of this issue for the past
several years, working to empower the CIO of the VA by providing him
with centralized authority over IT personnel, IT management, and IT
investment across the Department. As a result of your efforts, the
Office of the CIO is finally empowered to develop, plan, and budget for
a major data processing center consolidation initiative that would
significantly consolidate the VA’s existing decentralized IT
infrastructure. This initiative should not only be maintained, it should
be accelerated. Significant steps can immediately be taken to reduce the
data security threat within the VA; however, given the magnitude of the
VA IT enterprise, only after an aggressive consolidation initiative
would the Department realistically be in position to perform a high
quality information assessment, develop comprehensive security strategy
and policy, as well as implement the necessary technology, methodology,
and automated enforcement controls to achieve comprehensive information
security across the enterprise.
An information-centric approach must be supported not only by
technology, but more importantly, by people and processes. Organizations
should assess the security of their information by classifying data and
understanding where those data reside, document and communicate their
security policies clearly, enforce the policies appropriately, remediate
violations to the policies swiftly, and prove compliance quickly and
easily.
This problem is big and the Department of Veterans Affairs is not alone.
Today, there exist thousands of technologies that address security. We
believe that the plethora of vendors and point products on the market is
confusing to security buyers and implementers. Some basic principles of
IT best practices – consolidation, standardization, centralized
management and control, and the classification of data and systems based
on their sensitivity and mission criticality – make this endeavor
significantly more feasible. In short, security must become
information-centric.
Mr. Chairman, thank you for the opportunity to testify before your
Committee. I look forward to your questions and those of the Committee.
