PCI DSS

PCI DSS (Payment Card Industry Data Security Standard) defines technical and operational requirements for protecting payment-account data in environments that store, process or transmit it and may also cover service providers able to affect its security. Scope starts with data flows and connected systems, not a generic server list. Requirements address networks, configuration, access, vulnerabilities, logs, testing and policy. Compliance does not eliminate risk or replace other obligations. Validation depends on the entity’s role and payment-brand or acquirer requirements. Reducing stored data, segmenting correctly and retaining evidence can simplify assessment, but every exclusion needs justification and periodic verification. Applicability should be confirmed with current PCI SSC material and relevant parties rather than inferred from a product or marketing claim.
