All financial companies must clearly outline internal procedures that define how the integrity and security of private data will be maintained at rest and in transit, as required by:
- Gramm-Leach Bliley Act (GLBA)
- Sarbanes-Oxley 404 and 409 (SOX)
- Dodd-Frank Wall Street Reform and Consumer Protection Act
Financial institutions are bound by the Check Clearing for the 21st Century Act (or Check 21 Act) that allows banks to substitute original paper checks with a digital version. The transfer of these digital checks must be protected.
For record-keeping, Basel III requires financial organizations to provide tracking, auditing, and guaranteed delivery of transferred files with non-repudiation.
