Overview

The Payment Card Industry Data Security Standard (PCI DSS) was developed to encourage and enhance cardholder data security and facilitatethe broad adoption of consistent data security measures globally. PCI DSS provides a baseline of technical and operational requirements designed to protect account data. PCI DSS applies to all entities involved in payment card processing—including merchants, processors, acquirers, issuers, and service providers. PCI DSS also applies to all other entities that store, process or transmit cardholder data (CHD) and/or sensitive authentication data (SAD).

PCI Data Security Standard Requirements and Security Assessment Procedures, combines the 12 PCI DSS requirements and corresponding testing procedures into a security assessment tool. It is designed for use during PCI DSS compliance assessments as part of an entity’s validation process. The following sections provide detailed guidelines and best practices to assist entities prepare for, conduct, and report the results of a PCI DSS assessment.

PCI DSS comprises a minimum set of requirements for protecting account data, and may be enhanced by additional controls and practices to further mitigate risks, as well as local, regional and sector laws and regulations. Additionally, legislation or regulatory requirements may require specific protection of personal information or other data elements (for example, cardholder name). PCI DSS does not supersede local or regional laws, government regulations, or other legal requirements.

The PCI DSS security requirements apply to all system components included in or connected to the cardholder data environment. The cardholder data environment (CDE) is comprised of people, processes and technologies that store, process, or transmit cardholder data or sensitive authentication data. “System components” include network devices, servers, computing devices, and applications. Examples of system components include but are not limited to the following:

• Systems that provide security services (for example, authentication servers), facilitate segmentation (for example, internal firewalls), or may impact the security of (for example, name resolution or web redirection servers) the CDE.

• Virtualization components such as virtual machines, virtual switches/routers, virtual appliances, virtual applications/desktops, and hypervisors.

• Network components including but not limited to firewalls, switches, routers, wireless access points, network appliances, and other security appliances.

• Server types including but not limited to web, application, database, authentication, mail, proxy, Network Time Protocol (NTP), and Domain Name System (DNS).

• Applications including all purchased and custom applications, including internal and external (for example, Internet) applications.

• Any other component or device located within or connected to the CDE.
