Use of weak or not validated cryptographic algorithms undermines the purposes of utilizing encryption and digital signatures to protect data. Weak algorithms can be easily broken and not validated cryptographic modules may not implement algorithms correctly. Unapproved cryptographic modules or algorithms should not be relied on for authentication, confidentiality or integrity. Weak cryptography could allow an attacker to gain access to and modify data stored in the database as well as the administration settings of SQL Server.
Applications, including DBMSs, utilizing cryptography are required to use approved NIST FIPS 140-2 validated cryptographic modules that meet the requirements of applicable federal laws, Executive Orders, directives, policies, regulations, standards, and guidance.
Operations that require the use of cryptography include the provisioning of digital signatures, the generation and validation of cryptographic hashes, and the protection of data by storing and transmitting it in encrypted form.
The security functions validated as part of FIPS 140-2 for cryptographic modules are described in FIPS 140-2 Annex A.
SQL Server complies with FIPS 140-2 if Windows is configured to do so.
NSA Type-X (where X=1, 2, 3, 4) products are NSA-certified, hardware-based encryption modules. |
