Should sensitive data be stored on
laptops?
BOSTON, Massachusetts (AP) -- Every month
seems to bring another episode of sensitive personal
information escaping into the wild because a corporate or
government laptop computer is lost or stolen. A common
response is a lot of hand-wringing over how the data should
have been encrypted.
But some key
questions usually go unanswered. Why is so much private data
allowed to be on laptops to begin with? What do people do all
day that compels them to tote around records on, say, 26
million Americans, the staggering number seen in the recent
Veterans Affairs case?
"It's pure
laziness. There's actually no excuse for it," said Avivah
Litan, a security analyst for Gartner Inc. "There's no good
business reason for it."
Litan advocates a
few simple steps: Organizations should keep sensitive
information only on secure, centralized servers. Workers can
access the data from PCs in the office or over private
Internet connections, but can't store the records on their own
machines to fiddle with them offline.
Many companies give
storage-rich laptops to employees whether they really need
them or not.
If they absolutely
need to analyze data out of the office, the employees should
run programs that replace live credit card or Social Security
numbers with random "dummy" figures whenever possible, since
the actual numbers aren't always relevant.
Following such
rules would have prevented the scare that resulted when a
laptop with veterans' data was burgled from an analyst's home
May 3 (it was later recovered with the information apparently
unaccessed). The VA inspector general told Congress that the
staffer had been bringing data home for policy analysis since
2003.
It's true that
encrypting data -- scrambling them with private codes -- can
make whatever is found on a laptop almost impossible to read.
But encryption often isn't turned on by users who think it
degrades computer performance.
Consider the case
of the ING Financial Services adviser who had Social Security
numbers and other personal data for 13,000 District of
Columbia employees on his laptop -- until the computer was
stolen from his home last month. ING administers pensions for
the district.
The adviser had
broken ING rules by not having the data encrypted. ING
responded by recalling all employees' laptops to ensure that
encryption software was turned on and couldn't be switched
off.
But the fact that
the information was out of the office was not itself a
violation.
ING officials said
the adviser had the records because they corresponded to older
pension plan participants who were more likely to call him for
assistance. The adviser also wanted the data on hand for
potential marketing efforts, such as to help decide whom to
invite to a finance seminar.
Now, in light of
the laptop episode, ING is reconsidering whether sensitive
data should be allowed to leave the nest at all, even if it is
encrypted.
Steve Van Wyk,
ING's chief information officer, believes the emergence of
ubiquitous broadband connections and secure Web-based business
software have made it unnecessary for employees to store
private data on portable devices. Not only is that data
diaspora a security risk, but it also can be costlier for the
company to make sure back-office files and mobile data are in
sync, he said.
"The ability to
control it and protect it may be best if it's centralized," he
said. "Why even go through the vulnerability?"
To a large degree,
the problem of personal data floating away with laptops stems
from companies' tardiness in accepting just how valuable the
information is. Otherwise such records would have long been
treated like product designs, market intelligence and other
business secrets that aren't allowed to leave secure central
computers.
But it's not clear
this problem will ever go away.
Many mobile workers
want to keep information "locally" on their laptops so they
can work efficiently while traveling, meeting with clients or
pounding away in other settings where they can't connect to a
network. That's why they're often allowed -- even encouraged
-- to take laptops home.
That was the case
for an employee of investment adviser Ameriprise Financial
Inc. who had 158,000 clients' account information on a laptop
stolen in January.
Ameriprise
spokesman Steven Connolly said the worker was one of "very few
people" in the company allowed to keep that kind of personal
data on his own machine. Connolly would not explain what the
man -- a corporate-level staffer who did not interact with
clients -- did that required such intimate access.
In February, a
similar theft hit an Ernst & Young consultant, who lost
names, addresses and credit card information on 243,000
Hotels.com customers.
Ernst & Young
spokesman Charlie Perkins would not say why the consultant
needed to hold so much live personal information. Perkins said
the firm was confident, however, that its policy of encrypting
all 30,000 of its consultants' laptops -- a step that was
being implemented when the theft occurred -- would prevent
future incidents while preserving the staff's
mobility.
Even if employees
technically aren't supposed to walk out the door with
computers, many will quietly transfer business files to iPods,
"thumb" drives and other capacious storage devices, said Sunil
Jain, senior consultant for Sprint Enterprise Mobility Inc.,
the services arm of Sprint Nextel Corp.
"It's much faster
to download the data and then do the reports offline," Jain
said. "It's just human nature."
Jain finds that
even though he knows his company's central servers are
supposed to back up key files every night, he does the same on
his laptop just in case. He expects that's a common move,
especially since many companies -- including his -- tend to
give increasingly storage-rich laptops to employees whether
they really need them or
not.
