controls::database manager configuration parameter trust allclnts

Overview

The TRUST_ALLCLNTS database manager configuration parameter is only active when the authentication parameter is set to CLIENT which is not a recommended setting as discussed in the authentication parameter section. If the parameter is set to YES, the server assumes that the client side is handling authentication to the database. If the parameter is set to NO, the client must provide authentication to the server on behalf of the user.

The recommended value for this parameter is NO.

Rationale:

If the server trusts the client to authenticate the connecting user, a malicious user can connect to the database as any user including a database administrator by simply creating that user on the client system.

Skipping

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

1) Add db2_secured::controls::database_manager_configuration_parameter_trust_allclnts: skip to your hiera data. This will skip this control for ALL databases.
2) Add db2_secured::controls::database_manager_configuration_parameter_trust_allclnts::instance_name::dbname: skip to your hiera data. This will skip this control for specified database only.
3) Add an entry with the content database_manager_configuration_parameter_trust_allclnts to the array value db2_secured::skip_list in your hiera data.

title

The database identifier to apply the control to.

All controls need an database identifier to apply the control to. Here is a simple example:

db2_secured::controls::control_name { 'db2inst1/MYDB':}

In this example, the string dbinst1 is the instance, the string MYDB is the database to apply the control to.
