The PCI Data Security Standard represents a common set of industry tools and measurements to help ensure the safe handling of sensitive information. Initially created by aligning Visa's Account Information Security (AIS)/Cardholder Information Security (CISP) programs with MasterCard's Site Data Protection (SDP) program, the standard provides an actionable framework for developing a robust account data security process - including preventing, detecting and reacting to security incidents. The updated version, version 1.1, developed by the founding members of the PCI Security Standards Council, became effective with the launch of the PCI Security Standards Council.
