Annals of Electronic Information Security

At The Hill, former House Speaker Newt Gingrich raises a good point about the leak of hundreds of thousands of diplomatic cables and other private information:

"You have a private first class who downloads a quarter million documents, and the system doesn't say, 'Oh, you may be over extended?' I mean, this is a system so stupid that it ought to be a scandal of the first order," Gingrich said.

Regardless of which administration(s) are responsible (these systems probably took many years to reach their current form), one wonders if commercial EMR's suffer from the same oversights.

Insurers Test Data Profiles to Identify Risky Clients

Stories like this one today at the WSJ disturb me.

“Insurers Test Data Profiles to Identify Risky Clients”
Wall Street Journal
Nov. 19, 2010

From that story:

Life insurers are testing an intensely personal new use for the vast dossiers of data being amassed about Americans: predicting people’s longevity.

Insurers have long used blood and urine tests to assess people’s health—a costly process. Today, however, data-gathering companies have such extensive files on most U.S. consumers—online shopping details, catalog purchases, magazine subscriptions, leisure activities and information from social-networking sites—that some insurers are exploring whether data can reveal nearly as much about a person as a lab analysis of their bodily fluids.

In one of the biggest tests, the U.S. arm of British insurer Aviva PLC looked at 60,000 recent insurance applicants. It found that a new, “predictive modeling” system, based partly on consumer-marketing data, was “persuasive” in its ability to mimic traditional techniques.

The research heralds a remarkable [alarming? -ed.] expansion of the use of consumer-marketing data, which is traditionally used for advertising purposes.


Read the entire article.

The reason I find this article disturbing is that it can and probably should be looked at as another example of technophiles and opportunists with no knowledge of (or lack of caring about) Social Informatics, a decades-old discipline with a focus on studying the unintended consequences of new information and communications technologies (ICT's), enabling our society to move one step closer to centralized control.

Social Informatics (SI) refers to the body of research and study that examines social aspects of computerization, including the roles of information technology in social and organizational change, the uses of information technologies in social contexts, and the ways that the social organization of information technologies is influenced by social forces and social practices.

Stories such as the above WSJ story, and others in their running series on Internet privacy, also dampen my enthusiasm about the possibility that electronic medical information will be kept private, confidential and secure.

Medical data breach of the week - but your EMR data is secure, trust us, we're IT experts

I have written frequently about the pipe dream of secure national electronic medical records, such as in Febraury 2010 at my post "Networked EMR's and Healthcare Information Security: Practical When Massive IT Security Breaches Continue?", my post "Networked, Interoperable, Secure National Medical Records a Castle in the Sky?", as well as "Operation Aurora And a Widespread Reluctance to Discuss IT Flaws: Is Universal Healthcare IT Really a Good Idea in 2010?" and others.

I was also quoted on July 30, 2010, in a Philadelphia Inquirer story about the theft of a laptop computer with data on 21,000 patients from Thomas Jefferson University Hospital here, and also interviewed August 2 by local NPR station WHYY-91FM, where I stated:

"There is almost no excuse for unencrypted data to be sitting on any computer at a hospital or any organization," said Scot Silverstein, a Drexel University expert on health-information technology.

In the latest health-data-on-computer-theft-of-the-week, the Inquirer ran this story today about a local theft ten times as large as July's:

Medical-data breach said to be major
A computer flash drive containing the names, addresses, and personal health information of 280,000 people is missing - one of the largest recent security breaches of personal health data in the nation.

"We deeply regret this unfortunate incident," said Jay Feldstein, the president of the two affiliated Philadelphia companies, Keystone Mercy Health Plan and AmeriHealth Mercy Health Plan.

The breach, which involves the records of Medicaid recipients, is the first such Medicaid data breach in Pennsylvania since at least 1997, according to the state's Department of Welfare, which has oversight.

There is little more I can add to my prior postings on this issue except the words of privacy advocate, psychiatrist Dr. Deborah Peel:

The security failure, one of the several largest in nearly two years, involves nearly two-thirds of the insurers' subscribers. It became known only after The Inquirer requested information Tuesday evening. The insurers said the drive was missing from the corporate offices on Stevens Drive in Southwest Philadelphia. It noted that the same flash drive was used at community health fairs.

"That seems grossly irresponsible," said Dr. Deborah Peel, a Texas psychiatrist who heads Patient Privacy Rights, an advocacy group.

"Why would you be hauling around private patient information to a health fair," she said. "I can't imagine what they were thinking, taking this data out of a locked room at company headquarters.

"What's tragic is that this is a particularly vulnerable group of people," Peel said. "They tend to be vulnerable to identity theft, vulnerable to discrimination." Medicaid recipients are low-income people.


As to encryption (a built-in feature of the upper tier versions of Windows and of Mac OS X):

They [the companies] would not comment on the riskiness of taking the drive to health fairs, nor would they say whether the data on the drive was encrypted.

Highly likely translation: no.

The companies issued an apology:

"At Keystone Mercy Health Plan and AmeriHealth Mercy Health Plan, our number one priority is our members. Since reporting this unfortunate incident to the Department of Public Welfare, we have actively and responsibly executed a multifaceted plan to inform those affected, while also evaluating and enhancing our security measures to ensure this does not happen again."

[Did any employee have their "privileges revoked" -- the medical term of art for a physician who is 'fired' -- I wonder? - ed.]

Perhaps the executives in charge of this data, as well as the IT department, should read stories like the aforementioned July 30, 2010 story.

However, I fear there are those who are ineducable or hopelessly irresponsible when it comes to acting cautiously and responsibly regarding computer-based medical information, in the poorly bounded, complex, unpredictable world of healthcare.

That is not to even mention deliberate theft for personal gain.

This is why the dream of
secure national electronic medical records seems a pipe dream for the foreseeable future.

10/23 Addendum

in an updated story, the Inquirer reports the data was indeed unencrypted, although the companies claimed an encryption project was in progress.

Networked EMR's and Healthcare Information Security: Practical When Massive IT Security Breaches Continue?

At "Networked, Interoperable, Secure National Medical Records a Castle in the Sky?" I wrote that the holy grail of electronic medical record efforts - the creation of a networked, interoperable, secure national medical records system - may be far more difficult than anyone expected due to vulnerabilities in current, widespread IT networking and OS platforms.

Now we hear the situation is even worse than in the articles I cited at that post:


Wall Street Journal

Broad New Hacking Attack Detected

Global Offensive Snagged Corporate, Personal Data at nearly 2,500 Companies; Operation Is Still Running

Hackers in Europe and China successfully broke into computers at nearly 2,500 companies and government agencies over the last 18 months in a coordinated global attack that exposed vast amounts of personal and corporate secrets to theft, according to a computer-security company that discovered the breach.

The damage from the latest cyberattack is still being assessed, and affected companies are still being notified. But data compiled by NetWitness, the closely held firm that discovered the breaches, showed that hackers gained access to a wide array of data at 2,411 companies, from credit-card transactions to intellectual property.

One can only imagine how internet-connected hospitals, generally an IT backwater, might fare under such an onslaught.

... In more than 100 cases, the hackers gained access to corporate servers that store large quantities of business data, such as company files, databases and email.

They also broke into computers at 10 U.S. government agencies. In one case, they obtained the user name and password of a soldier's military email account, NetWitness found. A Pentagon spokesman said the military didn't comment on specific threats or intrusions.

At one company, the hackers gained access to a corporate server used for processing online credit-card payments. At others, stolen passwords provided access to computers used to store and swap proprietary corporate documents, presentations, contracts and even upcoming versions of software products, NetWitness said.

Data stolen from another U.S. company pointed to an employee's apparent involvement in criminal activities; authorities have been called in to investigate, NetWitness said. Criminal groups have used such information to extort sensitive information from employees in the past.


Read the while article. These breaches are an unpleasant reality in 2010, but what's worse is there really are no solid metrics for the true extent of this 'disease.'

Perhaps future Internet technologies will reduce or eliminate the problem, as one reader suggested in a comment to my aforementioned post. I do not believe, however, that patients and their medical records should be used as guinea pigs until those new networking and security technologies are widely deployed and well-proven.

In effect, this is probably not a good time for actual records-level interoperability to be deployed in any manner other than in consideration of a future strategy. Operationalizing that strategy should probably await a time when the "digital ether" in which the data resides and moves is more mature, unless proprietary networks and technology are to be used and without connection to the Internet. Planning data-level compatibility between systems, on the other hand, is work that should continue.

Finally, the layoffs and staffing levels in today's IT departments (at both vendor and user shops), plus the outsourcing of critical IT functions to overseas contractors where workers' loyalty to the primary firm is questionable at best, may be a contributing factor to the nakedness of corporate America's information systems.

Networked, Interoperable, Secure National Medical Records a Castle in the Sky?

The holy grail of electronic medical record efforts of late is the creation of networked, interoperable, secure national medical records that would allow a physician in Palo Alto to retrieve the records of a patient from Hoboken if that patient moved or was found (in the hackneyed and somewhat histrionic scenario) unconscious on the streets of San Francisco.

Recent events have made me skeptical we are anywhere near ready for such a technological accomplishment:

McAfee: Big Business Under Constant Cyber Attack
01.29.10

At the World Economic Forum Annual Meeting in Switzerland, McAfee announced the results of a survey of 600 IT security execs in "critical infrastructure enterprises worldwide": that is, in places such as utility companies, banks, and even oil refineries. And apparently, they're constantly under cyber attack and also extortion related to those attacks.


It's a real battlefield out there.

The report, written by the Center for Strategic and International Studies (CSIS), says that 54 percent of those surveyed have already been attacked. The culprits behind the cyber-attacks are listed as "organized crime-gangs, terrorists, or nation-states."

In other words, not simply teenage hackers or cyber-papparazi interested in the medical condition of a movie star.

Only one-fifth of the IT execs surveyed believe their systems are currently secure. One-third say things are worse now, vulnerability-wise, than a year ago, due to budget cuts.

What constitutes a cyber attack? A distributed denial of service (DDoS) is the most typical ... mitigation can be hampered by the local laws, working in multiple countries, or the economics of where they operate. For example, half of those surveyed claim the laws in their countries don't do enough to prevent or deter cyber attacks. That's especially true for Russia, Mexico, and Brazil.

Other attack vectors include DNS poisoning where Web traffic is redirected, SQL injection attacks on back-end data via a public Web site, and plain old theft of services.

If you need a plot for your new thriller novel, keep in mind that 20 percent of these companies are not just cyber-attacked, but have also been threatened with attacks in the last two years in "low-level extortion" attempts.

... Those surveyed said the money loss is the worst part, second is the loss of reputation, and (if you thought you weren't important) loss of customers' personal information is third.

This is a worldwide survey, and almost two-thirds of those surveyed believe foreign governments were responsible in some way for previous attacks. The two countries considering the biggest threats: China (by 33 percent of those surveyed) and the good ol' U.S. of A. (by 36 percent). China believes it's the biggest target.

The full report, called In the Crossfire: Critical Infrastructure in the Age of the Cyber War is free on McAfee's Web site in PDF format.

I note that Google recently called in the National Security Agency to help analyze a major corporate espionage attack:

The attacks targeted Google source code -- the programming language underlying Google applications -- and extended to more than 30 other large tech, defense, energy, financial and media companies. The Gmail accounts of human rights activists in Europe, China and the United States were also compromised.

Then there's this:

Intelligence Chief: U.S. at Risk of Crippling Cyber Attack

Feb. 4, 2010

The United States is at risk of a crippling cyber attack that could "wreak havoc" on the country, Director of National Intelligence Dennis Blair said.

"What we don't quite understand as seriously as we should is the extent of malicious cyberactivity that grows, that is growing now at unprecedented rates, extraordinary sophistication," Blair said.

... He said one critical "factor" is that more and more foreign companies are supplying software and hardware for government and private sector networks. "This increases the potential for subversion of the information in ... those systems," Blair said. [Outsourcing our HIT development overseas sounds like a great idea - ed.]


Read the linked articles in their entirety.

Perhaps we should focus on the local at present. National networked EMR's are a great concept, but there are a few social-technical details that remain to be worked out beforehand.


A Castle in the Sky...
