Trustworthy Configuration

Microsoft.SQLServer.2016.Database.Configuration.TrustWorthy (UnitMonitor)

Monitors the Trustworthy setting for the database. Note: This monitor is disabled by default. Please use overrides to enable it when necessary.

Knowledge Base article:

Summary

This monitor checks the Trustworthy setting for this database. Since this monitor is a part of an overall standards requirement, an alert would be generated if the setting does not meet the specified standard.

Configuration

The TRUSTWORTHY setting is used to indicate whether the instance of SQL Server trusts the database and the contents within it. When the Trustworthy setting is ON, database modules (for example, user-defined functions or stored procedures) that use an impersonation context can access resources outside the database.

To minimize security risks, TRUSTWORTHY should be OFF. When it is OFF, “EXECUTE AS USER” is scoped to the database itself and only those CLR assemblies marked as SAFE can be used. You should only have it ON if you are sure that your application requires it.

TRUSTWORTHY {ON | OFF}

Causes

A warning alert will be raised if the option does not match the required setting. Out of the box, the monitor is configured to alert when this setting is set to “ON”.
