This PCI-DSS network data flow diagram is a visual representation of your organization's computer network that can take a high-level or detailed approach. A PCI-DSS network data flow diagram must encompass all cardholder data environments, connected networks, and other IT resources. The PCI Security Standards Council offers testing procedures for merchants to check and verify their compliance efforts and specifies the DSS Requirements. To maintain compliance, merchants should perform these testing procedures regularly (or partner with a PCI DSS expert) and after any network or CDE changes.
