Does the 'CLR Assembly Permission Set' of SQL Server Hardening affect Dynamics CRM functionality?

Posted on by Edward TsDS 14
Hi frends,
 
Does the 'chapter 6.2 CLR Assembly Permission Set' of 'CIS_Microsoft_SQL_Server_2016_Benchmark_v1.3.0.pdf' SQL Server Hardening affect Dynamics CRM functionality? 
How to deal with the 'MSCRMSqlClr' assembly is 'UNSAFE_ACCESS' in the sql server?
 
Has anyone ever done this?
 
It is my pleasure if you give any suggestion, thanks in advance guys.
 
 
 
Cause: 
the SQL Server hardening is necessary, so when i follow the pdf to run the sql srcipt it return /MSCRMSqlClr    UNSAFE_ACCESS/,  
RunReturned
USE [CRM_Database_of_org_01];
GO
SELECT 
    name,
    permission_set_desc
FROM 
    sys.assemblies
WHERE 
    is_user_defined = 1;
MSCRMSqlClr    UNSAFE_ACCESS
 
i am afread that i have to follow the chapter 6.2 of the 'CIS_Microsoft_SQL_Server_2016_Benchmark_v1.3.0.pdf' to run another sql script to alter the 'permission_set' to 'SAFE' of the 'MSCRMSqlClr' assembly.
 
below is the screenshot of the chapter 6.2 of the 'CIS_Microsoft_SQL_Server_2016_Benchmark_v1.3.0.pdf':

    Not an easy answer i guess, since there is no much public documentation about this assembly from CRM.
     
    The only context is this documentation:
     
    If we try to find v9.0 / v9.1 documentation, the CLR section doesnt exist anymore, meaning v8.2 does uses this assembly, while v9.0/9.1 doesn't (confirmed).
    So if you are using v9, i would say you are probably fine.

    Without much confidence, but just my 2 cents.

    I follow the pdf to run the sql script, then i do a simple test in the CRM, no issue for now, so i decide to keep it.
