The cross db ownership chaining option controls cross-database ownership chaining across all databases at the instance (or server) level.

When enabled, this option allows a member of the db_owner role in a database to gain access to objects owned by a login in any other database, causing an unnecessary information disclosure. When required, cross-database ownership chaining should only be enabled for the specific databases requiring it instead of at the instance level for all databases by using the ALTER DATABASESET DB_CHAINING ON command. This database option may not be changed on the master, model, or tempdb system databases.

This control is used in the following benchmarks:


To deliberately skip this control (e.g. meaning don’t use Puppet to enforce this setting), we provide you with three ways:

1) Add mssql_secured::controls::cross_db_ownership_chaining_server_configuration_option_is_set_to0: skip to your hiera data. This will skip this control for ALL databases.
2) Add mssql_secured::controls::cross_db_ownership_chaining_server_configuration_option_is_set_to0::dbname: skip to your hiera data. This will skip this control for specified database only.
3) Add an entry with the content cross_db_ownership_chaining_server_configuration_option_is_set_to0 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:

mssql_secured::controls::control_name {'MSSQLSERVER':}

In this example, the string DB is the database to apply the control to.
