Payment Card Industry Data Security Standard (PCI DSS)

The PCI DSS is a set of security standards designed to ensure that all companies that accept, process, store, or transmit credit card information maintain a secure environment. It was established by major credit card companies to protect cardholder data and reduce credit card fraud.

The standard includes requirements for the following:

  • security management
  • policies
  • procedures
  • network architecture
  • software design
  • other critical protective measures

Companies that process card transactions must be PCI DSS compliant, and this often involves undergoing a formal PCI DSS assessment conducted by a qualified security assessor (QSA).

Non-compliance can result in fines, increased transaction fees, and even loss of the ability to process credit card transactions. It’s essential for businesses of all sizes to understand and implement the requirements of PCI DSS. This includes the following:

  • maintaining a secure network
  • protecting cardholder data
  • managing vulnerabilities
  • implementing strong access controls
  • monitoring and testing networks
  • maintaining an information security policy
