The idea: Penalize a site’s ranking in search engine results if the site suffers a security breach.
Now, for some background and details…
In December 2013 Target revealed that it had suffered a significant breach that exposed over 40 million credit card numbers. A month later it upped the count to 70 million and noted the stolen information included customers’ names, mailing addresses, phone numbers, and email addresses.
Does anybody care?
Or rather, what do they care about? Sure, the media likes stories about hacking, especially ones that affect millions of their readers. The security community marks it as another failure to point to. Banks will have to reissue cards and their fraud departments be more vigilant. Target will bear some costs. But will customers really avoid it to any degree?
Years ago, in 2007, a different company disclosed its discovery of a significant breach that affected at least 40 million credit cards. Check out the following graph of the stock price of the company (TJX Holdings) from 2006 to the end of 2013.
Notice the dip in 2009 and the nice angle of recovery. The company’s stock didn’t take a hit until 2009 when TJX announced terms of its settlement. The price nose-dived, only to steadily recover as consumers stopped caring and spent money (amongst any number of arbitrary reasons, markets not being as rational or objective as one might wish).
Consider who bears the cost of breaches like these. Ultimately, merchants pay higher fees to accept credit cards, consumers pay higher fees to have cards. And, yes, TJX paid in lost valuation over a rather long period (roughly a year), but only when the settlement was announced — not when the breach occurred. The settlement suggests that lax security has consequences, but a breach in and of itself might not.
Truth of Consequences
But what if a company weighs the costs of a breach as more favorable than the costs of increasing security efforts? What if a company doesn’t even deal with financial information and therefore has no exposure to losses related to fraud? What about companies that deal in personal information or data, like Snapchat?
Now check out another chart. The following data from Quantcast shows daily visitors to a lyrics site. The number is steady until one day — boom! — visits drop by over 60% when the site is relegated to the backwaters of search results.
Google caught the site (Rap Genius) undertaking sociopathic search optimization techniques like spreading link spam. Not only does spammy, vapid content annoy users, but Google ostensibly suffers by losing users who flee poor quality results for alternate engines. (How much impact it has on advertising revenue is a different matter.) Google loses revenue if advertisers care about where the users are or they perceive the value of users to be low.
The two previous charts have different time scales and measure different dimensions. But there’s an underlying sense that they reflect values that companies care about.
Think back to the Target breach. (Or TJX, or any one of many breaches reported over the years, whether they affected passwords or credit cards.)
What if a penalty affected a site’s ranking in search results? For example, it could be a threshold for the “best” page in which it could appear, e.g. no greater than the fourth page (where pages are defined as blocks of N results, say 10). Or an absolute rank, e.g. no higher than the 40th entry in a list.
The penalty would decay over time at a rate, linear or exponential, based on any number of mathematical details. For example, a page-based penalty might decay by one page per month. A list-based penalty might decay by one on a weekly basis.
If the search engines drives a significant portion of traffic — that results in revenue or influences valuation — then this creates an incentive for the site to maintain strong security. It’s like PCI with different teeth. It might incentivize the site to react promptly to breaches. At least one hopes.
But such a proposal could have insidious consequences.
Suppose a site were able to merely buy advertising to artificially offset the rank penalty? After a breach you could have a search engine that’d love to penalize the “natural” ranking of a site only to rake in money as the site buys advertising to overcome the penalty. It’s not a smart idea to pay an executioner per head, let alone combine the role with judge and jury.
A penalty that a company fears might be one for which it suppresses the penalty’s triggers. Keeping a breach secret is a disservice to consumers. And companies subject to the S.E.C. may be required to disclose such events. But rules (and penalties) need to be clear in order to minimize legal maneuvering through loopholes.
The proposal also implies that a search engine has a near monopoly on directing traffic. Yes, I’m talking about Google. The hand waving about “search engines” is supposed to include sites like Yahoo! and Bing, even DuckDuckGo. But if you’re worried about one measure, it’s likely the Google PageRank. This is a lot of power for a company that may wish to direct traffic to its own services (like email, shopping, travel, news, etc.) in preference to competing ones.
It could also be that the Emperor wears no clothes. Google search and advertisements may not be the ultimate arbiter of traffic that turns into purchases. Strong, well-established sites may find that the traffic that drives engagement and money comes just as well from alternate sources like social media. Then again, losing any traffic source may be something no site wants to suffer.
Target is just the most recent example of breaches that will not end. Even so, Target demonstrated several positive actions before and after the breach:
– Transparency — periodic updates on breach details, remediation steps, complaint process.
Thankfully, there were no denials, diminishing comments, or signs of incompetence on the part of Target. Breaches are inevitable for complex, distributed systems. Beyond prevention, goals should be minimizing their time to discovery and maximizing their containment.
And whether this rank idea decays from indifference or infeasibility, its sentiment should persist.
