Ensure the 'sa' Login Account is set to 'Disabled'

高级别 1自动化mssql

说明

The sa account is a widely known and often widely used SQL Server account with sysadmin privileges. This is the original login created during installation and always has the principal_id=1 and sid=0x01. Enforcing this control reduces the probability of an attacker executing brute force attacks against a well-known principal.
