💼 4.2.1 Strong cryptography and security protocols are implemented to safeguard PAN during transmission over open, public networks.

  • ID: /frameworks/pci-dss-v4.0/04/02/01

Description​

As following:

  • Only trusted keys and certificates are accepted.
  • Certificates used to safeguard PAN during transmission over open, public networks are confirmed as valid and are not expired or revoked. This bullet is a best practice until its effective date; refer to applicability notes below for details.
  • The protocol in use supports only secure versions or configurations and does not support fallback to, or use of insecure versions, algorithms, key sizes, or implementations.
  • The encryption strength is appropriate for the encryption methodology in use.
