Ensure the public role in the msdb database is not granted access to SQL Agent proxies

СредњаНиво 1Аутоматскаmssql

Опис

The public database role contains every user in the msdb database. SQL Agent proxies define a security context in which a job step can run. Granting access to SQL Agent proxies for the public role would allow all users to utilize the proxy which may have high privileges. This would likely break the principle of least privileges.

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

1. Ensure the required security principals are explicitly granted access to the proxy (use sp_grant_login_to_proxy). 2. Revoke access to the <proxyname> from the public role. USE [msdb] GO EXEC dbo.sp_revoke_login_from_proxy @name = N'public', @proxy_name = N'<proxyname>'; GO
