The Payment Card Industry (PCI) Security Standards Council has defined twelve high-level data security requirements, each of which includes multiple lower level requirements.
The PCI Data Security Standard (PCI DSS) requirements apply to any network component, server, or application that is included in or connected to the cardholder data environment.
Many of the requirements put the responsibility on the payment card processing organization to use the server at the center of the cardholder data environment in a secure way. ClearPath Dorado servers, running the OS 2200 operating system, provide the necessary security features and flexibility for you to meet and sometimes exceed these requirements.
The requirements in this paper are quoted from the PCI DSS Version 3.1, which became effective in April, 2015.
