PCI Resource Access
This report collects data on access attempts to PCI resources in the cardholder data environment and provides the compliance manager with visibility into all authentication attempts. Use this report to identify access attempts by users to ensure that access to cardholder data is legitimate.
You should limit access to resources in the PCI cardholder data environment to only those whose jobs require such access. This limits the risk that an account with access to cardholder data is compromised. PCI DSS requires that all authentication attempts to systems, applications, and devices in the cardholder data environment be monitored for appropriate and legitimate access.
Relevant data sources
