DS11.2:

DS 11.2 Storage and Retention Arrangements

Control Objective:
Define and implement procedures for data storage and archival, so data remain accessible and usable. The procedures should consider retrieval requirements, cost-effectiveness, continued integrity and security requirements. Establish storage and retention arrangements to satisfy legal, regulatory and business requirements for documents, data, archives, programs, reports and messages (incoming and outgoing) as well as the data (keys, certificates) used for their encryption and authentication.

Applicability:

Sarbanes-Oxley

HIPAA

GLBA

PCI

FISMA

NIST SP 800-66

Ditscap

Risk Association Control Activities:

• PCI.3.3: Mask account numbers when displayed (the first six and last four digits are the maximum number of digits to be displayed).
  

• PCI.3.4: Render sensitive cardholder data unreadable anywhere it is stored (including data on portable media, backup 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 AES 256-bit with associated key management processes and procedures.
  

• PCI-4.1.1 For wireless networks transmitting cardholder data, encrypt the transmissions by using Wi-Fi Protected Access (WPA) technology if WPA capable, or VPN or SSL at 128-bit. Never rely exclusively on WEP to protect confidentiality and access to a wireless LAN. Use one of the above methodologies in conjunction with WEP at 128 bit, and rotate shared WEP keys quarterly and whenever there are personnel changes.
