Ensure Windows local groups are not SQL Logins

SedangLevel 1Otomatismssql

Deskripsi

Local Windows groups should not be used as logins for SQL Server instances. Default: By default, no local groups are added as SQL logins. Runs one sqlcmd query with its defaults (Windows authentication to the local default instance); set SQLCMDSERVER, SQLCMDUSER and SQLCMDPASSWORD for another instance or SQL authentication. Needs VIEW SERVER STATE / sysadmin-level read access.

Cara perbaikan

Metode perbaikan: Panduan atau patch infrastruktur

1. For each LocalGroupName login, if needed create an equivalent AD group containing only the required user accounts. 2. Add the AD group or individual Windows accounts as a SQL Server login and grant it the permissions required. 3. Drop the LocalGroupName login using the syntax below after replacing <name>. USE [master] GO DROP LOGIN [<name>] GO
