controls::restrict access to sysproc auth list roles for authid

Overview

The table function SYSPROC.AUTH_LIST_ROLES_FOR_AUTHID returns the roles for the specified authorization ID. In a non-restrictive database this table function has EXECUTE granted to public. It is recommended that public should not be able to execute this routine.

Rationale:

A malicious user may use this function to conduct information gathering regarding the roles that a user belongs to.

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

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.
