PCI DSS Noncompliance Linked to Increased Breach Risk

For the second year in a row, a Verizon report has found that too many businesses are struggling to comply with payment card security standards, putting consumers’ confidential information at risk. 


According to the Verizon Payment Card Industry Compliance Report, most businesses that accept credit or debit cards, or both, continue to struggle to achieve and maintain compliance with the Payment Card Industry Data Security Standard (PCI DSS).  As a result, they are at greater risk of losing confidential customer information and falling victim to credit-card fraud.


Businesses are failing to maintain compliance even though they face steep penalties, including fines and increased transaction fees from the credit card brands.  Businesses also now face pressure from their partners and customers to demonstrate continued compliance.


In addition to analyzing the overall current state of compliance with the PCI DSS, the report examines how well organizations comply with the 12 specific PCI requirements and provides recommendations that organizations can implement to help them earn and maintain compliance.


“We had hoped to see more organizations complying with the PCI standard, since we believe that compliance will ultimately improve the security posture of organizations and in all likelihood lead to fewer breaches,” says Wade Baker, director of risk intelligence, Verizon. 


The report includes data from organizations based in the U.S., Europe and Asia, representing for the first time the global nature of the PCI standard.


The report highlights that while the compliance situation has neither worsened nor improved, it is still “disappointing.” Only 21 percent of organizations were fully compliant during the initial audit. 


The report notes that the difficulty in achieving compliance, along with overconfidence, complacency and the need to focus on other compliance and security issues are among the possible reasons for the widespread PCI noncompliance.


The report demonstrated again this year that breached organizations are more likely not to be PCI compliant and are more likely to suffer from identity theft and fraud issues.


Organisations struggled the most to comply with requirements 3 (protect stored cardholder date), 10 (track and monitor access), 11 (regularly test systems and processes), and 12 (maintain security policies), all of which are directly linked to protecting cardholder data.

The report found that rather than using a risk-based approach to PCI compliance, organisations instead rely on the PCI DSS for guidance.  As a result, many organisations are ignoring security threats with the highest risk and potential for the largest negative impacts.


Malware and hacking are the most predominant methods used to gain access to cardholder data.   Several overlapping PCI requirements are aimed at protecting against these attack methods. 


Based on extensive analysis, Verizon offers the following recommendations to help organisations meet their PCI compliance goals:


Treat compliance as an everyday, ongoing process. Compliance requires continuous adherence to the standard. This means a daily log review, weekly file-integrity monitoring, quarterly vulnerability scanning and annual penetration testing.  


To achieve this, Verizon recommends that an internal PCI “champion” ensure that compliance becomes part of daily business activities.


Self-validate very carefully – or not at all.  Level 1 and 2 merchants -- who process the highest volumes of cardholder transactions --are allowed to assess themselves against the standard. 


Due to the numerous issues and conflicts of interest this can cause, Verizon highly recommends that an objective third party validate the scope of the assessment or perform the testing.


Prepare to have the bar raised.   In October 2010, the PCI Security Standards Council announced PCI DSS version 2.0.  This version requires a more stringent executive summary and validation of methodology for scope definition. 


Organisations, many of which are having severe issues complying with the existing standards, need to quickly get ready for the new version.
