Brand Reciprocity Revoked by Visa and MasterCard: What It Means for Merchants
Brand reciprocity refers to how the card brands acknowledge the different merchant levels of the other card brands. For example, if an organization is a Level 2 Visa merchant but a Level 4 MasterCard merchant (both designations based upon transaction volume), brand reciprocity means that the merchant would be classified as a Level 2 merchant.

Internal Penetration Testing: Attacking Systems That Matter
When you are conducting internal penetration tests in large environments, prioritizing attacks can be a challenging task, because of the number of systems and vulnerabilities. Attacks performed during testing are commonly prioritized based on the nature and severity of the vulnerabilities identified. However, the effectiveness of that approach can be greatly increased by focusing on […]

“60 Minutes” on Cyber Security Risks
On November 8, CBS’s “60 Minutes” ran a segment on information security weaknesses called “Sabotaging The System.” This piece highlighted security vulnerabilities in segments of our nation’s critical infrastructure, including banking, power, and national defense. In addition, former and current government officials confirmed that the threats exist; not only are probes and attacks occurring with […]

Do Not Use the Back Door!
In system development a “backdoor“ creates a way of bypassing normal authentication to allow access to a system. Secret backdoor credentials often exist deep in the thousands or millions of lines of code that make up a system. This is just one reason why building your own user management/authorization/authentication schemes into systems is a bad […]

PCI in Europe Today
I attended the 2009 PCI Community meeting in Europe last week. Since this was a feedback year, there wasn’t a significant amount of new content; however, there were some interesting points regarding PCI adoption in Europe. It’s been discussed quite frequently that the Europeans are behind North America in implementing PCI, especially at the merchant […]

Vulnerability Scanning with Multiple Products
Should you rely on just one solution to identify all of your vulnerabilities? Most of us rely upon just one anti-virus scanner, right? Every vulnerability scanner claims to be better than its competitors, but how could this be? Where is the Consumer Reports on this subject? I think there is a mix of reasons why […]

European PCI Community Meeting: Some Impressions
The trip back to the U.S. from the European PCI Community Meeting in Prague took about 12 hours. For someone who lives and breathes PCI, that equals one hour for each of the 12 requirements of the Data Security Standard (DSS). Here are my impressions of the conference. First, the PCI Security Standards Council did […]

Where the CISO Reports
Since the role of the Chief Information Security Officer (CISO) and how he or she reports has a major impact on security and risk, I think it’s interesting to look at how different organizations have structured the position. With that said, there is very little consistency other than a correlation with the industry vertical’s understanding […]
