4.2.29 Restrict Access to SYSCAT.SECURITYPOLICYCOMPONENTRULES

Information

The SYSCAT.SECURITYPOLICYCOMPONENTRULES view contains the read and write access rules for security label components. It is recommended that the PUBLIC role be restricted from accessing this view.

Rationale:

Any databases created without the RESTRICT option automatically GRANT the SELECT privilege to PUBLIC for SYSCAT views. Therefore, it is strongly recommended to explicitly REVOKE the SELECT privilege on the SYSCAT.SECURITYPOLICYCOMPONENTRULES view from PUBLIC to reduce risk to the organization's data.

Solution

Perform the following to revoke access from PUBLIC.

Connect to the Db2 database.

db2 => connect to <dbname>

Run the following command:

db2 => REVOKE SELECT ON SYSCAT.SECURITYPOLICYCOMPONENTRULES
FROM PUBLIC
