Which category is NOT part of the PCI DSS requirements?

The category that is not part of the PCI DSS requirements is related to Sales Management Procedures. The PCI DSS (Payment Card Industry Data Security Standard) focuses on safeguarding cardholder data and protecting payment card transactions. The essential requirements encompass areas such as ensuring that cardholder data is securely stored and transmitted, implementing robust access controls, and maintaining a comprehensive information security policy to guide organizations in their security practices.

While sales processes might be important for a business, they do not fall under the specific requirements outlined in the PCI DSS. The standard is focused on issues directly relevant to data security and protecting sensitive payment information rather than general business management or sales-related procedures. Therefore, Sales Management Procedures are not included in the PCI DSS framework, highlighting the critical focus of the standard on data security aspects essential for compliance.
