CloudCard shall evaluate the risks inherent in processing and storing data, and shall implement cryptographic controls to mitigate those risks where deemed appropriate. Where encryption is in use, strong ensure that all non-public data is encrypted at rest and in transit over public networks. Strong cryptography with associated key management processes and procedures shall be implemented and documented for all encryption usage. All encryption shall be performed in accordance with industry standards, including NIST SP 800-57.
