controls::restrict access to sysibm sysschemata

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 SYSIBM.SYSSCHEMATA table contains all schema names in the database. It is recommended that the PUBLIC role be restricted from accessing this table.

Rationale

PUBLIC should not have access to see all the schema names in the database because this could be used as a point of exploit.

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

Benchmarks

This control is used in the following benchmarks:

• db11 CIS V1.0.0 - paragraph 4.3.26

Attributes

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.
