Review: The Art of the Humble Inquiry
Humble Inquiry: The Gentle Art of Asking Instead of Telling
Edgar H Schein
Edgar Schein says we have a cultural issue. We like to tell people what we think, rather than asking them what they’re trying to tell us. Overall, especially in the world of information technology, I tend to agree. To counter this problem, he suggests that we perfect the art of the humble inquiry — redirecting our thinking from the immediate solution that comes to mind, or even from the question that was asked, and trying to get to the what the person we’re talking to is actually asking.
He gives numerous examples throughout the book; perhaps my favorite is of the person who asked stopped their car while he was doing yard work to ask directions to a particular street. Rather than answering, he asked where they were trying to get to. They were, in fact, off course for their original plan, but he directed them down a different path that got them there faster than if they’d turned around and found their way back to that original path. This is a perfect example of asking returning a specific question with a larger question — an authentic Continue reading

Stretched Firewalls across Layer-3 DCI? Will the Madness Ever Stop?
I got this question from one of my readers (and based on these comments he’s not the only one facing this challenge):
I was wondering if you can do a blog post on Cisco's new ASA 5585-X clustering. My company recently purchased a few of these with the intent to run their cross data center active/active firewalls but found out we cannot do this without OTV or a layer 2 DCI.
A while ago I expressed my opinion about these ideas, but it seems some people still don’t get it. However, a picture is worth a thousand words, so maybe this will work:

CloudFlare is now PCI 3.1 certified
The Payment Card Industry Data Security Standard (PCI DSS) is a global financial information security standard that keeps credit card holders safe. It ensures that any company processing credit card transactions adheres to the highest technical standards.
PCI certification has several levels. Level one (the highest level) is reserved for those companies that handle the greatest numbers of credit cards. Companies at level one PCI compliance are subject to the most stringent checks.
CloudFlare’s mission leads it to provide security for some of the most important companies in the world. This is why CloudFlare chose to be audited as a level one service provider. By adhering to PCI’s rigorous financial security controls, CloudFlare ensures that security is held to the highest standard and that those controls are validated independently by a recognised body.

This year’s update from PCI 2.0 to 3.1 was long overdue. PCI DSS 2.0 was issued in October 2010, and the information security threat landscape does not stand still—especially when it comes to industries that deal with financial payments or credit cards. New attacks are almost Continue reading
