Missing the (opportunity of) Target

You may have heard that some companies lost some credit card data recently.  I think it was in the news.  Come to think of it, a couple of weeks ago I featured a great guest post by Jeff Man on the topic.

In recent stories it has come out that some of the compromised companies “ignored thousands of alerts”, and many folks are heaping scorn and derision on the compromised companies because victim-blaming is easier than looking inward and securing their own stuff.  Also, unless we have a historical record of “normal” alert levels for these environments, and average false positive rates, with statistical deviation analysis- let’s not assume “X-thousand alerts” means a damned thing.  I generate thousands of alerts in my own labs playpens without even trying, I can’t imagine what kind of background noise a global retailer has.

Oh, and millions of people had cards compromised.  And the impact on the vast majority was nothing.  At least nothing more than getting a new card in the mail.  The payment card security system is, in my opinion, badly broken- but it functioned as designed, and consumers were protected (in that the built-in margins designed to cover fraud covered the fraud to protect the consumers).

There has, of course, been renewed cry for chip and pin cards to replace the US-only magnetic stripe cards of antiquity we cling to.  And, of course, the expected backlash against chip and pin being  an imperfect solution, and thus not worth the effort- forget that getting a little better tomorrow is still a laudable (and arguably the only viable) goal.

And all of this misses a huge opportunity.  An opportunity to make consumers like me happy.  I understand that I am not normal, on a bewildering array of scales of normalcy, but I’m not alone in traveling outside of North America.  I have found myself in subway and train stations late at night, across Europe, with a pocketful of useless US credit cards and no way to buy a ticket without a chip and pin card, the standard for most of the rest of the world.  That’s just plain stupid.

I’ve been plenty of other places where my retro-tech US cards didn’t work, but the “late at night in a transit station” one REALLY sucks.  Now there’s word that we’ll finally start moving away from the old magnetic stripe cards… and the latest is that we will get “chip and signature”, not chip and pin- so much for compatibility.

What we have is an opportunity to make customers and some merchants happier by standardizing technology across the globe- and we could slide a little increase in security into the process at the same time.  But noooooo.  The payment card industry gets it wrong, again.

Glad we never miss opportunities like that in InfoSec.

Recovered yet?

I think I have.  I am, of course, talking about the annual week of madness in San Francisco.

Security BSides San Francisco was another great event, lots of diverse and thought-provoking content, and plenty of good conversations- as we expect from BSides.  The planned lead organizer for BSides San Francisco had a change in career path, and a few of the BSides regulars had to step up and make the event happen- it is amazing working with the folks who make BSides happen, it looked easy from the outside.  And there are new folks ready to take the lead for BSidesSF 2015, so we’ll see you there next year.

Believe it or not, there was a lot more than BSides happening that week.  The RSA/NSA controversy didn’t appear to have any impact on the RSA conference, there were almost 30,000 people in attendance and a record number of vendors, with an expanded vendor expo area.  I was pleased to see a significant reduction in the number of scantily clad women working the booths, but I’m still struggling to understand the significance of a boxing ring in an infosec booth, other than as a bad metaphor.  And nothing, absolutely nothing, says “enterprise security” to me like some dude juggling while riding a unicycle in an expo booth.  At least he was fully dressed.  I had a lot of good conversations at RSA again this year, but the expo floor seemed unusually devoid of innovation.  I didn’t get to do a full crawl of the smaller booths on the edges of the big hall, but it really looked like a “yelling about nothing” year to me.  Terms like “threat intelligence” and “big data” were everywhere, but definitions for “threat intelligence” were often unintelligible.  Patrick Gray’s interview of Marcus Ranum summed it up pretty well (37 second mp3).

I did not make it to TrustyCon, the event spun up to provide an alternative for those who pulled talks from RSA, and a place to focus on trustworthy computing- but it sounded like it had some great content and I hope it grows into a focused event to provide insight and context to the challenges of privacy and security in our “post-Snowden” world.  They seem to be off to a good start.  (Yes, some folks seem to be playing the RSA/NSA story for media and PR, but many folks involved in TrustyCon are, I believe, truly sincere).

Once again the real value of the RSA conference for me was having thousands of people in one area, I had several informative meetings, and many good conversations in and around San Francisco that week.  Speaking of which, as soon as the Spare Time Fairy pays me an overdue visit, I want to write up some of what’s new with Denim Group’s ThreadFix project, cool things are happening there.
