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

中等級 1自動化mssql

說明

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.

檢查方式

稽核方法: SQL 查詢

sql_query

sqlcmd -b -h -1 -W -Q "SET NOCOUNT ON; SELECT CASE WHEN CAST(value AS int) = 0 AND CAST(value_in_use AS int) = 0 THEN 'compliant' ELSE 'noncompliant' END FROM sys.configurations WHERE name = 'Ad Hoc Distributed Queries';"

預期輸出: compliant

修補方式

修補方法: SQL 陳述式

shell

sqlcmd -b -h -1 -W -Q "SET NOCOUNT ON; EXEC sp_configure 'show advanced options', 1; RECONFIGURE; EXEC sp_configure 'Ad Hoc Distributed Queries', 0; RECONFIGURE; EXEC sp_configure 'show advanced options', 0; RECONFIGURE;"
