If SQL Server authentication, using passwords, is employed, SQL Server must enforce the DoD standards for password complexity.
Medium Severity
<VulnDiscussion>Windows domain/enterprise authentication and identification must be used (SQL4-00-030300). Native SQL Server authentication may be used only when circumstances make it unavoidable; and must be documented and AO-approved. The DoD standard for authentication is DoD-approved PKI certificates. Authentication based on User ID and Password may be used only when it is not possible to employ a PKI certificate, and requires AO approval. In such cases, the DoD standards for password complexity must be implemented. The requirements for password complexity are: a. minimum of 15 Characters, 1 of each of the following character sets: - Upper-case - Lower-case - Numeric - Special characters (e.g. ~ ! @ # $ % ^ & * ( ) _ + = - ' [ ] / ? > <)]; b. Minimum number of characters changed from previous password: 50% of the minimum password length (that is, 8). To enforce this in SQL Server, configure each DBMS-managed login to inherit the rules from Windows.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
