Description
The TRUSTWORTHY database setting restricts access to database resources by databases that contain assemblies with the EXTERNAL_ACCESS or UNSAFE permission settings and modules that use impersonation of accounts assigned elevated privileges. Unless all assemblies and code for the database have been reviewed, especially in the case where databases have been detached and attached between server instances, leaving the TRUSTWORTHY status to off can help reduce threats from malicious assemblies or modules.
