Moving to EMV compliant terminals is not a plug-and-play endeavor. You can’t simply plug them in, turn them on and expect everything to work. Changes are needed to the software for supporting point-of-sale systems (cash registers). You will likely need to provision keys to devices; if you manage keys internally you will also need to make sure everything is safely stored in an HSM. There are often required changes to back-office software to sync up with the POS changes. IT staff typically need…

Rich here.

I’m going to pull an Adrian this week, and cover a few unrelated things. Nope, no secret tie-in at the end, just some interesting things that have hit over the past couple weeks, since I wrote a Summary.

Living with the OPM Hack

Rich · July 16, 2015

And yep, thanks to his altruistic streak even Rich is affected. We don’t spend much time on blame or history, but more on the personal impact. How do you move on once you know much of your most personal information is now out there, you don’t know who has it, and you don’t know how they might want to use it?

Incite 7/15/15 — On Top of the Worlds

Mike Rothman · July 15, 2015

I discussed my love of exploring in the last Incite, and I have been fortunate to have time this summer to actually explore a bit. The first exploration was a family vacation to NYC. Well, kind of NYC. My Dad has a place on the Jersey shore, so we headed up there for a couple days and took day trips to New York City to do the tourist thing.

This is the second post in our series on the “liability shift” proposed by EMVCo – the joint partnership of Visa, Mastercard, and Europay. Today we will cover the basics of what the shift is about, requirements for merchants, and what will happen to those who do not comply. But to help understand we will also go into a little detail about payment providers behind the scenes.

Threat Detection Evolution: Quick Wins

Mike Rothman · July 14, 2015

As we wrap up this series on Threat Detection Evolution, we’ll work through a quick scenario to illustrate how these concepts come together to impact on your ability to detect attacks. Let’s assume you work for a mid-sized super-regional retailer with 75 stores, 6 distribution centers, and an HQ. Your situation may be a bit different, especially if you work in a massive enterprise, but the general concepts are the same.

Incite 7/1/2015: Explorers

Mike Rothman · July 1, 2015

When I take a step back I see I am pretty lucky. I’ve seen a lot of very cool places. And experienced a lot of different cultures through my business travels. And now I’m at a point in life where I want to explore more. Not just do business hotels and see the sights from the front seat of a colleague’s car or taxi. I want to explore and see all the cool things this big world has to offer.

October 1st, 2015, is the deadline for merchants to upgrade “Point of Sale” and “Point of Swipe” terminals to recommended EMV compliant systems. To quote Wikipedia, “EMV (Europay MasterCard Visa), is a technical standard for smart payment cards and for payment terminals and automated teller machines which can accept them.” These new terminals can validate an EMV specific chip in a customer’s credit card on swipe, or validate a secure element in a mobile device when it is scanned by a terminal.…

Threat Detection: Analysis

Mike Rothman · June 29, 2015

As discussed in our last post, evolved threat detection’s first step is gathering internal and external security data. Once you have the data aggregated you need to analyze it to look for indications that you have compromised devices and/or malicious activity within your organization.

Rich here,

Yep, it looks very likely my personal data is now in the hands of China, or someone pretending to be China, or someone who wants it to look like China. While I can’t go into details, as many of you know I’ve done things with the federal government related to my rescue work. It isn’t secret or anything, but I never feel comfortable talking specifics because it’s part-time and I’m not authorized to represent any agency.
