Available now on the PCI SSC website (PDF), version 3.0 becomes effective on Jan. 1. Version 2.0 will remain active until Dec. 31, 2014, to ensure adequate time for organizations to make the transition.
Many of the key changes to the guidelines are designed to make compliance more of a regular process, rather than a report on a company's compliance at a specific point in time, according to the council and other experts.
"Version 3.0 will help organizations make payment security part of their business-as-usual activities by introducing more flexibility, and an increased focus on education, awareness and security as a shared responsibility," the PCI Council says. "Overall updates include specific recommendations for making PCI DSS part of everyday business processes and best practices for maintaining ongoing PCI DSS compliance; guidance from the Navigating PCI DSS Guide built in to the standard; and enhanced testing procedures to clarify the level of validation expected for each requirement."
"PCI DSS is stressing that their compliance standard is not a set-it-and-forget-it mentality," says Joe Schumacher, security consultant at Neohapsis, which helps enterprises with PCI assessment.
"Some important areas in this new mentality focus on security processes," Schumacher says in a blog. "For example, entities should be validating on their own that controls are implemented effectively for applicable businesses processes and related technologies. Some specific examples related to this new mentality focus on antivirus definitions, logging, vulnerability signatures and ensuring that only appropriate services are enabled on systems.
"With this new mentality, entities should look to take corrective actions when compliance gaps are identified so that PCI DSS compliance can be maintained at all times and not wait until their [auditor] comes to validate their compliance."
Some experts said the new guidelines don't go far enough.
"Overall, the council has made some excellent improvements to the standard, but the risk management area of PCI 3.0 still needs more work," says Michael Aminzade, director of compliance delivery at Trustwave. "The main area of concern is that even though the new standards reference risk management strategies that must be met, the standard doesn't enforce companies to adopt any of those strategies. In particular, the standard doesn't address the fact that risk assessments need to be done by an industry-certified professional and are only performed on an annual basis. Also, PCI DSS 3.0 does not include any changes surrounding mobile security."
