Auditing Privacy Part 2 - Risk Assessment of Data Loss


The easy way to assess privacy risks is to focus on the impact of data theft to the organization by including the private data as a corporate asset. There are well documented methods to identify the vulnerabilities in means of collecting, storing and sharing the data. Similarly, there are methods to identify and list the data's threats (hackers, "insiders," and negligent loss). The impacts will likely shake out along the lines of direct costs (postage, call center, other incident response costs), potential legal and regulatory actions and reputation damage. (For an example, Protegrity assessed the TJX data breach at $1.7 billion, though TJX was not strictly a privacy issues, it has parallels*).


This would be the easy way, but may not result in the most accurate results. The problem lies in identifying the impacts of a privacy breach. The attribute of “privacy” assigned to the data is what makes the data valuable, and worthy of protection. However, "privacy" is not an attributed that belongs to the corporation, but to the individual the data describes. So an assessment of risk to the corporation of privacy loss should start at looking at the impact of the loss to the individual.


Why do many corporations, when disclosing losses of tremendous amounts of data, appear to suffer only short term damage to their reputation. I posit that the potential damage to a corporation is proportional to the actual real damage to privacy of the individuals described in the lost damage. (See Guin v Brazos)


The real impact of a privacy incident on individuals has been hidden behind a cloud of security vendor fear mongering and media induced panic. The common problems with the data is equating data loss with a privacy breach. Identity theft properly defined is likely a higher impact, lower frequency event than is commonly reported.


The SB1386-style disclosure laws have been a boon to identifying the frequency of data loss, but the information that has to be disclosed does little to help identify the impact. An auditor concerned strictly with compliance would have to place equal risk to any loss of private data. But the auditor should take the risk assessment to the next step and focus on the individuals, identifying the risks that lead to actual harm to the privacy of individuals. Compliance risk is equivalent for the loss of a laptop carrying an encrypted database of private data and the same databases being heisted off a web server unencrypted by a criminal with the intent to exploit the identities. The real risk to the privacy of the individuals described in the database is clearly different.


Beyond the risk of a data loss, the auditor should also consider the equally important risks of the collection of private data and the dossier-ification of data. More on that later.




*Why the high risk to TJX? Though not strictly a privacy issue, the damages related are an issue of a loss to a third party - the banks - rather than TJX itself.

Impacted Molars II


Occlusal
Panopticonistas Cyveillance say ID theft is so bad, we are all going to die. Seems like shutting down copyright scofflaws got a little too Web 1.0 for them, so they've unleashed their vicious crawling spiders on a search for contraband identities. And guess what they found out? EVERYBODY'S IDENTITY IS ALREADY PWN'D! Now that they've collected this data, I'm curious as to what are they going to do with all those credit card numbers, SSNs and mothers' maiden names. Did they help shut down the sites hosting the illicit data? Did they notify the victims? This sort of research is on an odd ethical footing. I hope they get it all sorted before they do their research on other forms of digital contraband.

Distal
California Secretary of State Debra Bowen kicks ass in the name of privacy for Californians. She gets privacy, and maybe even cares about the citizens of California. I wish she could impart some of her knowledge to the Texas county clerks.

Mandibular
CDT publishes their draft Privacy Principles for Identification. Seem pretty much like Fair Information Practices to me, which is not necessarily a bad thing.

Panopticon Enabled Desktops Increase Productivity!


From Dark Reading, the joys of workforce monitoring software with Ascentive!:

"We call it 'workforce activity management,'" says Schran. "Our latest edition provides all the insight necessary to eliminate time-wasting, increase productivity, and protect private company data."
Or, in the words of Ascentive's VP of Customer Relations Jeremy Bentham,

Morals reformed - health preserved - industry invigorated - instruction diffused - public burthens lightened - Economy seated, as it were, upon a rock - the gordian knot of Gramm Leach Bliley and Sarbanes-Oxley are not cut, but untied - all by a simple idea in Software Architecture!
More from Dark Reading:

Perhaps even more importantly, employee monitoring tools can deter workers from insider activities such as data theft or unauthorized file access, Schran adds. "If your employees are downloading files to a USB device, our software will record that action," he says. "Our data has already been used in evidentiary proceedings in court."


But I prefer the hot buzz on this product from their EU Product Evangelist Michel Foucault:

The heaviness of the old 'houses of security', with their fortress-like architecture, could be replaced by the simple, economic geometry of a 'house of certainty'. The efficiency of power, its constraining force have, in a sense, passed over to the other side - to the side of its surface of application. He who is subjected to a field of visibility, and who knows it, assumes responsibility for the constraints of power; he makes them play spontaneously upon himself; he inscribes in himself the power relation in which he simultaneously plays both roles; he becomes the principle of his own subjection. By this very fact, the external power may throw off its physical weight; it tends to the non-corporal; and, the more it approaches this limit, the more constant, profound and permanent are its effects: it is a perpetual victory that avoids any physical confrontation and which is always decided in advance.

And they say security software people don't read post-structuralist French philosophers. Heck, Foucault is all around you! I running a Jacques Derrida Packet Sniffer & Deconstructor right now! Or am I?

Auditing Privacy Part 1 - Ethics and the Canon

It would comfort many compliance auditors to discover the ultimate checklist and tear after their organization's privacy program, collecting tick marks and developing the dreaded deficiency finding. I say to them, "Google is your friend." For the more enlightened internal auditor, the first step in evaluating their organizations privacy practices should be a step back.

The Canon
There are best practices, and there are benchmarks. There are torts, laws, and rational fear of the irrational regulator. However, for most every auditable area there is also The Canon. Take a file to the gilded crust of Sarbanes-Oxley and the PCOAB (and all their works and all their ways), you eventually uncover the Generally Accepted Accounting Principles. Take a snowblower to the myriad layers of dust and ash of the Code of Federal Regulations. If you squint and hold your head just right, you'll see a vague outline of the Decalogue. And somewhere below ornate filigree and baroque ornamentation of HIPAA, Gramm Leach Bliley and SB1386 is the shape of the Fair Information Practices of the US Department of Health, Education and Welfare, 1973.

From the link above, here are the five practices of the modern privacy canon:

  1. Collection limitation
  2. Disclosure
  3. Secondary usage
  4. Record correction
  5. Security
These five principles will be your mantra for your audit. They will guide your question and inform your issues. Advanced practitioners may chose from the following according to their path:

The 10 AICPA's Generally Accepted Privacy Principles

The OECD Guidelines on the Protection of Privacy and Transborder Flows of Personal Data


The Ethos
Like the Torah, the Sermons of Buddha, the Qur'an, the Gospels, or Fermat's Principle, a canon is only meaningful if applied. You must ask the CEO, the CIO, the Chief Marketeer, the General Counsel, and listen, and interpret their answers accordingly. Are the principles used as values to guide their decisions, obstacles to be worked around, or are they simply unknown? Read your corporate policies regarding privacy. Do you see in them evidence of the Fair Information Practices, or do they appear to be more oriented to a specific set of industry specific regulations? Interview the folks who handle the data. Do they treat the data with the care they would treat their own? The answers to these questions will begin to lead you to determining if your organization has the ethical basis for a privacy program.

What Does This Mean?
A compliance oriented organization may maintain reasonable concordance with Fair Information Practices without even knowing what they are. However, the organization may be reactive, and inefficient. The organization's privacy direction will be dictated by outside entities, rather than developed within.
A organization with a firm foundation in privacy practices, coupled with an ethic duty to privacy, will be more efficient, more effective, and retain a better reputation in the face of an incident.

I Am Not A Cop


A couple posts on the role of internal audit in the information security controls of a company got me thinking.
First, Anton describes an auditor as "policing agent" model:

  • InfoSec develops controls.
  • Operations operationalizes them.
  • Audit goes around with a checklist to make sure they got done
Farnum at Computerworld comments, as does Rothman.

The issue I have with this model is that if what InfoSec develops are inadequate, they could still be well implemented. InfoSec should take ownership in the controls, and insure they are implemented and monitor their performance after they are implemented. When the auditor comes along, he or she should be looking not only at the implementation, but if the system as designed by InfoSec achieves the requisite goals of risk reduction acceptable to the board. Unlike the crime, systems development or drug prescription analogies, information security is an ongoing management process.

So I'm looking through rose colored glasses rather than my usual green eyeshade, but I'm not going to play Kavenaugh to bunch of Mackeys.

More Questions than answers

This evening has been spent practicing for my SXSW day show: a brief discussion about privacy for which some auditors will be getting CPE. As a result, I have also spent the evening listening to my voice slowly decay into a burbling croak.

But, I was happy that IT Security published what's on their blog feed. Some good stuff there, and I'm definitely subscribing to fellow Texan McKeay's keenly honed published thoughts. He nailed the county clerk bit better than I could. I could have saved some electrons and blood vessels if I read him first.

Speaking of privacy, my favorite bass player got in the mail a solicitation to participate in clinical study of some new medicine that replaces some prescription med. The suggested way to sign up was to go to a url: http://MYWIFESNAME.DRUGCOMPANYNAME.COM. That seemed odd. Half of me want to do some DNS-fu on the beast, see what names I can get (if any), and see what information I can gather. The other half of me is mildly outraged but barely has the energy to google to finder others in equivalently mild states of outrage. The third half feels like having a scotch and going to bed. Strictly for medicinal purposes. In Balvenie veritas.
