4.1: Safeguard Transmission of Cardholder Data   Strong cryptography and security protocols to safeguard sensitive cardholder data during transmission over open, public networks

Secure transmission of cardholder data requires using trusted keys/certificates, a secure protocol for transport, and proper encryption strength to encrypt cardholder data. Connection requests from systems that do not support the required encryption strength, and that would result in an insecure connection, should not be accepted. However, in case of misconfiguration on the access point or server level, additional verification of endpoint wireless connection configurations is recommended.
