According to a press release issued by the PCI SSC today, PCI DSS v3.1 is effective immediately and PCI DSS v3.0 will be retired on 30 June 2015.
According to the statement:
“The National Institute of Standards and Technology (NIST) identified SSL (a cryptographic protocol designed to provide secure communications over a computer network) as not being acceptable for the protection of data due to inherent weaknesses within the protocol. Upgrading to a current, secure version of Transport Layer Security (TLS), the successor protocol to SSL, is the only known way to remediate these vulnerabilities, which have been exploited by browser attacks such as POODLE and BEAST.”
The changes impact requirements 2.2.3, 2.3 and 4.1 in PCI DSS v3.0, which reference SSL as an example of “strong cryptography”.
While the revisions are effective immediately, impacted requirements have a sunset date to allow for organisations with affected systems to implement the necessary changes. The PCI DSS has summarised these as follows:
- “SSL and early TLS cannot be used as security controls to protect payment data after 30 June 2016.”
- “Prior to this date, existing implementations that use SSL and/or early TLS must have a formal risk mitigation and migration plan in place. Guidance on interim risk mitigation approaches, migration recommendations and alternative options for strong cryptographic protocols is outlined in the PCI SSC Information Supplement: Migrating from SSL and Early TLS.”
- “Effective immediately, new implementations must not use SSL or early TLS.”
- “Point-of-sale (POS)/Point-of-interaction (POI) terminals (devices such as magnetic card readers or chip card readers that enable a consumer to make a purchase) that can be verified as not being susceptible to all known exploits for SSL and early TLS may continue using these protocols as a security control after 30 June 2016.”
Help with PCI compliance
We advise organisations that need to comply with the PCI DSS to work with their PCI DSS provider to determine the impact of these changes and address them accordingly.
