    May 18, 2018, Karl Steinkamp, Director, PCI Product and Quality Assurance

    On Thursday, May 17, the PCI Security Standards Council (PCI SSC) released an updated version of the PCI DSS standard, primarily to include clarifications and minor revisions around controls that referenced SSL/early TLS.
