PCI-3.4

Render sensitive cardholder data unreadable anywhere it is stored, (including data on portable media, in logs, and data received from or stored by wireless networks) by using any of the following approaches:

• One-way hashes (hashed indexes) such as SHA-1
• Truncation
• Index tokens and PADs, with the PADs being securely stored
• Strong cryptography, such as Triple-DES 128-bit or Advanced Encryption Standard (AES) 256-bit with associated key management processes and procedures.

The MINIMUM account information that needs to be rendered unreadable is the payment card account number.

PCI-3.4 A: Obtain documentation about the cryptographic system used to protect stored data, including the vendor, type of cryptographic system, and the encryption algorithms. Verify that data is rendered unreadable using one of the following algorithms:

• One-way hashes (hashed indexes) such as SHA-1
• Truncation or masking
• Index tokens and PADs, with the PADs being securely stored
• Strong cryptography, such as Triple-DES 128-bit or Advanced Encryption Standard (AES) 256-bit, with associated key management processes and procedures.

PCI-3.4 B: Examine several tables from each database server in the sample of database machines to verify the data is encrypted (i.e., not stored in plain text).

PCI-3.4 C: Examine a sample of removable media (e.g., backup tapes) to confirm that cardholder data is encrypted.

PCI-3.4 D: Examine a sample of audit logs to confirm that cardholder data is sanitized or removed from the logs.

PCI-3.4 E: Verify that any cardholder data received from wireless networks is encrypted wherever stored.
