controls::disable instance discoverability

Overview

Puppet controls are Puppet defined types that ensure a certain security control is implemented. Puppet changes the system in order to make the system compliant.

Description of the control

The discover_inst parameter specifies whether the instance can be discovered in the network. It is recommended that instances not be discoverable.

Rationale

Discovery capabilities may be used by a malicious entity to derive the names of and target DB2 instances.

Skipping

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

1) Add db2_secured::controls::disable_instance_discoverability: skip to your hiera data. This will skip this control for ALL systems.
3) Add an entry with the content disable_instance_discoverability to the array value db2_secured::skip_list in your hiera data.

Benchmarks

This control is used in the following benchmarks:

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.
