controls::asymmetric key size is set to greater than or equal to 2048 in non system databases
Microsoft Best Practices recommend to use at least a 2048-bit encryption algorithm for asymmetric keys.
The RSA_2048 encryption algorithm for asymmetric keys in SQL Server is the highest bit-level provided and therefore the most secure available choice (other choices are RSA_512 and RSA_1024).
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!
If you you like he prospect of easy way into continuous compliancy with minimal fuss and bother, we suggest taking a look at our solution as your go-to option. Plus, our team can help you get up and running so that you can focus on other areas of your business. What are you waiting for? Get started today!
This control is used in the following benchmarks:
- Microsoft SQL Server Database 2014 CIS V1.5.0 - paragraph 7.2
- Microsoft SQL Server Database 2016 CIS V1.3.0 - paragraph 7.2
- Microsoft SQL Server Database 2017 CIS V1.2.0 - paragraph 7.2
- Microsoft SQL Server Database 2019 CIS V1.2.0 - paragraph 7.2
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::asymmetric_key_size_is_set_to_greater_than_or_equal_to_2048_in_non_system_databases: skip to your hiera data. This will skip this control for ALL databases.
mssql_secured::controls::asymmetric_key_size_is_set_to_greater_than_or_equal_to_2048_in_non_system_databases::dbname: skip to your hiera data. This will skip this control for specified database only.
3) Add an entry with the content
asymmetric_key_size_is_set_to_greater_than_or_equal_to_2048_in_non_system_databases to the array value
mssql_secured::skip_list in your hiera data.

The database to apply the control to.
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.
