Still think passwords are reliable? standard

Researchers Martin Vuagnoux and Sylvain Pasini recently released video demonstrating the ability to pull electromagnetic eminations from wired keyboards. Both videos show how various configurations of standard keyboards could have keystrokes intercepted through the air. Many of us have heard of the old TEMPEST project that was made famous by their demonstration of the ability to intercept the data that would be displayed on Cathode Ray Tube monitors. Imagine having someone sit outside your office or home and being able to see on their monitor the very same things you are looking at on yours. I wonder how many more corporate scandals would hit the press if this happened regularly. Now it appears that simply typing your passwords or authentication ...

PCI Europe Community Meeting, Q/A (Part 2) standard

Final round of questions from the field! The first question from this session was “Are end of life operating systems able to be used?” The thing that really worries me about retail is that information security does not seem to be built into the price of goods on the shelf. When someone asks if they are expected to replace hundreds or thousands of devices for PCI Compliance because Microsoft will not support them anymore, I worry more about the overall security of the company. This seems like a reactive approach without any forward strategy, which is unfortunately fairly common. I understand the business implications here. If your competitors are not doing this, you could face additional price pressures by trying ...

PCI Europe Community Meeting, Q/A standard

I always enjoy the Q/A sessions that the Council has at these events. I don’t know how many sessions I will be able to blog about (we only want the interesting ones anyway), but here’s the first bunch of Q/A from this session! The first question was around segmentation and SANs. I’d never heard the question asked that way, but most SANs by nature are segmented from each other. The more interesting point here is what constitutes segmentation? So many assessors only consider firewalls a method of segmentation. According to the documentation provided by the council, segmentation can be accomplished in multiple ways–not just by deploying firewalls. QSAs should be looking at the whole solution, not just fixating on a ...

October Herding Cats and Off to Brussels! standard

Greetings folks! Couple of updates in this post. October’s Herding Cats is up and ready for you to read! Pretty soon here I will be setting up a URL where you can download all the published versions of this column regardless of your membership status with the ISSA. Need a little time though baby birds. Until then, members of the ISSA can download the most recent version here. As you can tell, I have been reading a lot of James Patterson recently. Sorry about that. Also, if you are going to be at the PCI Europe Community Meeting this week, look me up! I’ll be wheels down in Brussels on Tuesday in time for the networking session. I am looking ...

PDF Wars: The Rise of the Evil Document standard

VeriSign’s Managed Security Services group provides all kinds of services to assist organizations in the heavy lifting associated with some security tasks. Those tasks that are easy if you have one, but not easy if you have a thousand. In a recent internal email string, one of our engineers told us they are seeing a dramatic increase in the amount of PDFs that have malicious JavaScript embedded in them. These exploits use the OpenAction function (like the HTML document.onload() function) as a vehicle to obtain full machine compromise with a root kit. I’m not sure why we feel the need to embed scripting into a PDF (isn’t that what the web and offline browsing is for?), but it appears that ...

So you think your memory is safe? standard

One of the topics that I often get into discussions with customers is pulling data out of volatile memory (RAM). The argument that is usually made related to insecure RAM storage is, “Well, someone would have to get on the machine and know exactly where to look in memory and it would just not be feasible for someone to do.” My response to this argument is typically something along the lines of “Obscurity is NOT Security.” Obscurity is a poor defense against security problems. It now appears there is evidence of malware that can grab data in memory to the hacker’s delight. It’s not really rocket science folks; it is actually pretty simple. This technique has legitimate uses in programming, ...

PCI Version 1.2 Changes standard

Are you interested in how 1.2 affects you? The Council provided a detailed list of changes between the two standards, but sometimes it can be a little overwhelming. The guys over at Aegenis have posted a good summary for those of you who want to cut to the chase. If you have specific questions to your business, why not reach out to a VeriSign consultant? We can provide you the expertise you need!

PCI-DSS V1.2 is RELEASED! standard

Just like the rest of you, I couldn’t sleep all night. I tossed and turned in anticipation for this glorious day. It was much like being a kid again and waiting for Christmas morning to hurry up and get here so I could open presents! I jumped out of bed promptly when my alarm went off, got ready for my day and bounded up my stairs to my new office (I’ve moved my office so that the new kiddo can get the bigger room), plopped myself into my chair and furiously tried to wake up my PC. I unlocked it and browsed over and … *sigh* should have slept in. I’ve been hitting reload every ten seconds since (Grey’s Anatomy ...

PCI-SSC, you are such a tease. standard

I wandered over to the PCI-SSC site today and noticed that they have reposted the press release from August 18 reminding everyone that the new version of the standard will be announced TOMORROW. Thanks for the reminder; I’m pretty sure we all have that date etched into our brains via green laser. Tease….

Thank you PCI-SSC and Orlando! standard

The US PCI Conference is now over, and what a quick two days. There are many changes coming for the new standard, and I’m very excited about talking to you all. We are putting together a webinar to discuss, in detail, the changes that you will be facing. Look for an announcement on that soon. It was great talking with many of you about the issues that we all face every day. I look forward to talking again soon and helping you build creative solutions to these challenges. Oh, and a quick tidbit for you all. If you get a business card from a processor, sometimes even when you put it in a blazing fire pit, it will not burn!
