Ensure 'Ad Hoc Distributed Queries' Server Configuration Option is set to '0'

中レベル 1自動mssql

説明

Enabling Ad Hoc Distributed Queries allows users to query data and execute statements on external data sources. This functionality should be disabled. Both value and value_in_use must equal 0. Default: By default, this option is disabled (0). 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.
