Setting CLR Assembly Permission Sets to SAFE_ACCESS will hinder assemblies from accessing external system resources such as files, the network, environment variables, or the registry. Assemblies with EXTERNAL_ACCESS or UNSAFE permission sets can be used to access sensitive areas of the operating system, steal and/or transmit data and alter the state and other protection measures of the underlying Windows Operating System. Assemblies which are Microsoft-created ( is_user_defined = 0 ) are excluded from this check as they are required for overall system functionality.
Solution
USE <database_name>; GO ALTER ASSEMBLY <assembly_name> WITH PERMISSION_SET = SAFE; Impact: The remediation measure should first be tested within a test environment prior to production to ensure the assembly still functions as designed with SAFE permission setting.
