Ensure the 'sa' Login Account has been renamed

MediaNivel 1Automatizadamssql

Descripción

The sa account is a widely known and often widely used SQL Server login with sysadmin privileges. The sa login is the original login created during installation and always has principal_id=1 and sid=0x01. It is more difficult to launch password-guessing and brute-force attacks against the sa login if the name is not known.
