Title

SQL Server must use NSA-approved cryptography to protect classified information in accordance with the data owner’s requirements.

Description

<VulnDiscussion>Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. The application must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated. It is the responsibility of the data owner to assess the cryptography requirements in light of applicable federal laws, Executive Orders, directives, policies, regulations, and standards. ...

Configure cryptographic functions to use NSA-approved cryptography compliant algorithms. Use DOD code-signing certificates to create asymmetric keys stored in the database used to encrypt sensitive data stored in the database. Run the following SQL script to create a certificate: USE CREATE CERTIFICATE ENCRYPTION BY PASSWORD = <'password'> FROM FILE = <'path/file_name'> WITH SUBJECT = 'name of person creating key', EXPIRY_DATE = '<'expiration date: yyyymmdd'>' Run the following SQL script to create a symmetric key and assign an existing certificate: USE CREATE SYMMETRIC KEY <'key name'> WITH ALGORITHM = AES_256 ENCRYPTION BY CERTIFICATE For Transparent Data Encryption (TDE): USE master; CREATE MASTER KEY ENCRYPTION BY PASSWORD = ''; CREATE CERTIFICATE . . .; USE ; CREATE ...
