4.1.1 Ensure wireless networks transmitting cardholder data or connected to the cardholder data environment, use industry best practices (for example, IEEE 802.11i) to implement strong encryption for authentication and transmission.

Note: The use of WEP as a security control is prohibited.

4.1.1 Identify all wireless networks transmitting cardholder data or connected to the cardholder data environment. Examine documented standards and compare to system configuration settings to verify the following for all wireless networks identified:
• Industry best practices (for example, IEEE 802.11i) are used to implement strong encryption for authentication and transmission.
• Weak encryption (for example, WEP, SSL version 2.0 or older) is not used as a security control for authentication or transmission.

Malicious users use free and widely available tools to eavesdrop on wireless communications. Use of strong cryptography can help limit disclosure of sensitive information across wireless networks.
Strong cryptography for authentication and transmission of cardholder data is required to prevent malicious users from gaining access to the wireless network or utilizing wireless networks to access other internal networks or data.
