Payment Card Industry (PCI)

Payment Card Industry (PCI) is a set of security standards that were developed by major credit card companies (including Visa, MasterCard, and American Express) to ensure the protection of sensitive cardholder information.

The Payment Card Industry Data Security Standard (PCI DSS) is a set of requirements that merchants and service providers who store, process, or transmit cardholder data must comply with in order to protect against data breaches and unauthorized access to cardholder information. The standard includes requirements related to data encryption, access control, vulnerability management, network security, and other security measures that are designed to protect against common types of attacks and data theft. The standard consists of 12 requirements, which are organized into six categories:

  1. Build and Maintain a Secure Network and Systems
  • Install and maintain a firewall configuration to protect cardholder data
  • Do not use vendor-supplied defaults for system passwords and other security parameters
  1. Protect Cardholder Data
  • Protect stored cardholder data
  • Encrypt transmission of cardholder data across open, public networks
  1. Maintain a Vulnerability Management Program
  • Protect all systems against malware and regularly update anti-virus software or programs
  • Develop and maintain secure systems and applications
  1. Implement Strong Access Control Measures
  • Restrict access to cardholder data by business need-to-know
  • Identify and authenticate access to system components
  • Restrict physical access to cardholder data
  1. Regularly Monitor and Test Networks
  • Track and monitor all access to network resources and cardholder data
  • Regularly test security systems and processes
  1. Maintain an Information Security Policy
  • Maintain a policy that addresses information security for all personnel

In the context of data privacy, PCI compliance is important because it helps ensure that sensitive cardholder information is handled and stored securely. Compliance with these requirements is mandatory for all organizations that accept credit card payments, and must be validated through regular security assessments conducted by qualified security assessors. Non-compliance with PCI standards can result in significant fines and penalties, as well as damage to a company's reputation and loss of customer trust.

It's important to note that compliance with PCI DSS is just one aspect of an overall data security strategy, and that organizations must take a holistic approach to data security that includes other measures such as employee training, incident response planning, and ongoing monitoring and risk assessments.
