controls::restrict access to sysibm syscoldist

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.SYSCOLDIST table contains the nth most frequent value of some column, or the nth quantile (cumulative distribution) value of the column. It is recommended that the PUBLIC role be restricted from accessing this table.

Rationale

Any databases created without the RESTRICT option automatically GRANT the SELECT privilege to PUBLIC for SYSIBM tables. Therefore, it is strongly recommended to explicitly REVOKE the SELECT privilege on the SYSIBM.SYSCOLDIST table from PUBLIC to reduce risk to the organization’s data.

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_syscoldist: skip to your hiera data. This will skip this control for ALL systems.
3) Add an entry with the content restrict_access_to_sysibm_syscoldist 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 4.3.4

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.
