Setting CLR Assembly Permission Sets to SAFE_ACCESS will prevent 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.
Excelent Compliance Solution.
Puppet is an excellent solution to ensure your databases are CIS or STIG compliant. Now you’re looking at information about only one compliance control, but managing total compliance isn’t hard either!

This control is used in the following benchmarks:
- Microsoft SQL Server Database 2014 CIS V1.5.0 - paragraph 6.2
- Microsoft SQL Server Database 2016 CIS V1.3.0 - paragraph 6.2
- Microsoft SQL Server Database 2017 CIS V1.2.0 - paragraph 6.2
- Microsoft SQL Server Database 2019 CIS V1.2.0 - paragraph 6.2
To deliberately skip this control (e.g. meaning don’t use Puppet to enforce this setting), we provide you with three ways:
mssql_secured::controls::clr_assembly_permission_set_is_set_to_safe_access_for_all_clr_assemblies: skip to your hiera data. This will skip this control for ALL databases.
mssql_secured::controls::clr_assembly_permission_set_is_set_to_safe_access_for_all_clr_assemblies::dbname: skip to your hiera data. This will skip this control for specified database only.
3) Add an entry with the content
clr_assembly_permission_set_is_set_to_safe_access_for_all_clr_assemblies to the array value
mssql_secured::skip_list in your hiera data.

All controls need an database to apply the control to. Here is a simple example:
In this example, the string DB is the database to apply the control to.
