Information
The SYSIBM.SYSSECURITYLABELS table contains security labels. 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.SYSSECURITYLABELS table 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 SYSIBM.SYSSECURITYLABELS FROM PUBLIC
