PCI Requirement 10.2.1 – All Individual User Accesses to Cardholder Data

Identifying Which Accounts Have Been Compromised

PCI Requirement 10.2.1 requires that audit trails reconstruct all individual user accesses to cardholder data. What is the purpose of PCI Requirement 10.2.1? The PCI DSS guidance explains, “Malicious individuals could obtain knowledge of a user account with access to systems in the CDE, or they could create a new, unauthorized account in order to access cardholder data. A record of all individual accesses to cardholder data can identify which accounts may have been compromised or misused.”

Anytime someone accesses cardholder data, a log should be generated. An assessor will work with your database and network administrators to verify that all individual accesses to cardholder data is logged.
