If SQL Server authentication, using passwords, is employed, SQL Server must enforce the DoD standards for password lifetime.


Overview

Finding ID Version Rule ID IA Controls Severity
V-72415 SQL2-00-038910 SV-87039r2_rule Medium
Description
Windows domain/enterprise authentication and identification must be used (SQL2-00-023600). 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 lifetime must be implemented. The requirements for password lifetime are: a. Password lifetime limits for interactive accounts: Minimum 24 hours, Maximum 60 days b. Password lifetime limits for non-interactive accounts: Minimum 24 hours, Maximum 365 days c. Number of password changes before an old one may be reused: Minimum of 5. To enforce this in SQL Server, configure each DBMS-managed login to inherit the rules from Windows.

Check Text ( C-72669r2_chk )
Run the statement:
SELECT
name
FROM
sys.sql_logins
WHERE
type_desc = 'SQL_LOGIN'
AND is_disabled = 0
AND is_expiration_checked = 0;

If no account names are listed, this is not a finding.

For each account name listed, determine whether it is documented as requiring exemption from the standard password lifetime rules, if it is not, this is a finding.
