Overview

The discover parameter determines what kind of discovery requests, if any, the DB2 server will fulfill. It is recommended that the DB2 server only fulfill requests from clients that know the given instance name (discover parameter value of known).

Rationale:

Discovery capabilities may be used by a malicious entity to derive the names of and target DB2 instances. In this configuration, the client has to specify a known instance name to be able to detect the instance.

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

Attributes

Attribute Name Short Description
title The database identifier to apply the control to.

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.
