The PCI Security Standards Council today published the expected update to PCI releasing these documents including some specific migration guidance:

• Press Release

Updates to the DSS Supporting documents like the ROC Reporting Instructions and to the PA-DSS Standard are expected to follow soon.

Some of the notable changes and guidance:

• PCI DSS v3.0 will be retired June 30, 2015
• All SSL and “early TLS” to be sunset by June 30, 2016 (see requirements 2.2.3, 2.3, 4.1)
• Unacceptable secure session transport (all versions of SSL, TLS 1.0, and some implementations of TLS 1.1)
• How to address SSL and early TLS in ASV scans
• POS terminals and their receiving gateways can continue  to use SSL and early TLS after the sunset date provided it can be verified that the implementation is not susceptible to known exploits.
• Clarifications on how to validate service providers and third party outsourcers
• Added 3.4.e to ensure truncated and hashed PAN stored together cannot be used to reconstruct the original PAN
• End-user protocols now includes the example of SMS (text messaging)
