Ensure no login exists with the name 'sa'

中级别 1自动化mssql

说明

The sa login (e.g. principal) is a widely known and often widely used SQL Server account. Therefore, there should not be a login called sa even when the original sa login (principal_id = 1) has been renamed. Enforcing this control reduces the probability of an attacker executing brute force attacks against a well-known principal name.
