controls::restrict access to tablespaces
Overview
A tablespace is where the data is physically stored. It is recommended that tablespace usage be restricted to authorized users.
Rationale:
Grant the USE
of tablespace privilege to only authorized users. Restrict the privilege from PUBLIC
, where applicable, as a malicious user can cause a denial of service at the tablespace level by overloading it with corrupted data.

Benchmarks
This control is used in the following benchmarks:
- DB2 Database 10 CIS V1.1.0 - paragraph 6.24
- DB2 Database 11 CIS V1.0.0.draft - paragraph 4.5.1
- DB2 Database 11 CIS V1.0.0 - paragraph 4.5.1
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_tablespaces: skip
to your hiera data. This will skip this control for ALL databases.
2) Add db2_secured::controls::restrict_access_to_tablespaces::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_tablespaces
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.
