PCI DSS 4.0
Req 1: Network Security Controls

PCI DSS 4.0 1.4.1: 1.4.1 NSCs between trusted and untrusted networks

Network security controls must be implemented between trusted and untrusted networks. The guidance explains this lets the entity monitor and control every connection into and out of trusted networks; the Requirement 1 overview lists the internet, business-to-business links, wireless, carrier and third-party networks, and corporate networks outside PCI DSS scope as examples of untrusted networks. Applicability: no special notes; applies to every assessed entity. Customized approach objective: unauthorised traffic cannot cross the boundary between trusted and untrusted networks.

Other controls in Req 1: Network Security Controls

You are reading one control. How much of PCI DSS 4.0 have you already done?

PCI DSS 4.0 1.4.1 is one control. If you already hold one of the frameworks below, a reviewed crosswalk already says how much of PCI DSS 4.0 your existing evidence covers. Hold ISO 27001:2022 and 139 of 280 PCI DSS 4.0 controls already carry evidence.

Each report names every control your existing framework evidences, every one it does not, the reasoning behind each claim, and the claims that were argued against and rejected. 415 were rejected on the ISO 27001:2022 pair alone.
