New Study Finds PCI DSS Compliant Companies Suffer Fewer Data Breaches
Yet most practitioners don't believe PCI DSS has positive effect on information security, finds report from The Ponemon Institute & Imperva
Compliant Organizations Suffer Fewer Breaches
According to the study, 64 percent of PCI-DSS compliant organizations reported suffering no data breaches involving credit card data over the past two years, while only 38 percent of non-compliant organizations reported suffering no breaches involving credit card data over the same period. When it comes to overall data breaches (general incident or those involving credit card data), 63 percent of compliant organizations suffered no more than a single data breach, compared to 22 percent of non-compliant organizations. Notably, 26 percent of non-compliant organizations suffered more than five breaches over the same time period.
"At the end of the day, we believe that PCI-DSS is one of the most effective data security regulations today and can significantly help companies improve their data security posture," says Amichai Shulman, co-founder and CTO of Imperva. "Most companies who make an effort to comply with the standards are likely to suffer fewer breaches than those who don't, period."
PCI-DSS Perception is Cynical
Despite evidence to the contrary, the study also found that 88 percent of respondents did not support the claim that PCI-DSS compliance has a positive effect on the number of breaches experienced, and only 39 percent mentioned data security improvement as one of the regulation's value propositions for business. In fact, only 33 percent believe that PCI-DSS compliance expenditure is covered by the value it brings to organization.
"Looking at the figures regarding the actual decrease in data breaches and recent figures regarding the cost of data breaches, it seems that many practitioners have a much subverted perception of the value of PCI-DSS compliance," said Larry Ponemon, chairman and co-founder of the Ponemon Institute.
Nonetheless Compliance Is Increasing
This year's report also found that two-thirds of respondents have achieved substantial compliance with PCI-DSS. In the 2009 PCI DSS Compliance Trends Study, the number of respondents who'd achieved similar levels of compliance was only half, and roughly 25 percent of respondents in 2009 had not achieved any level of compliance. Only 16 percent of organizations surveyed in 2011 have not achieved any level of PCI-DSS by comparison.
"Over the past few years, most companies have matured in their understanding of the PCI mandate and have worked to meet strict compliance deadlines," continued Shulman. "We believe this is one of the primary reasons we've seen an overall increase in compliance and also, we believe, a decline in the number of credit card-related data breaches."
"In an era where governments are struggling with the creation of vague yet complex data protection acts, the credit card industry took a bold step towards regulating itself, using plain language, clear goals and a pragmatic focus," said University of Connecticut School of Business Professor Robert Bird. "PCI isn't perfect - but it succeeded by imposing security mandates and forcing attention on data security - all without government regulation."
