3.1 Ensure the cassandra and superuser roles are separate

Profile Applicability

• Level 1 - Cassandra
• Level 1 - Cassandra on Linux

Description

The default installation of Cassandra includes a superuser role named cassandra. This necessitates the creation of a separate role to be the superuser role.

Rationale

Superuser permissions allow for the creation, deletion, and permission management of other users. Considering the cassandra role is well known it should not be a superuser or one which is used for any administrative tasks.

Impact

If a separate superuser account is not created and tested for correct functionality prior to removing the superuser role from the cassandra account you will no longer be able to perform certain actions, including:

• Create a role with super user status.
• Perform DROP or CREATE USER queries.

Audit

To verify the configuration, run the following query:

select role from system_auth.roles where is_superuser= True;

If you get an error 2200 [ INVALID QUERY] due to where clause, add "ALLOW FILTERING to end of query so it looks like below:

select role from system_auth.roles where is_superuser= True ALLOW FILTERING;

Looking at the role, verify any show up with is_superuser = True and make sure it is not cassandra or any unapproved role. If any are found then, this is a finding.

Remediation

To remediate a misconfiguration, perform the following steps:

1. Execute the following command:

create role '<NEW_ROLE_HERE>' with password='<NEW_PASSWORD_HERE>' and login=TRUE and superuser ;

  permissions   keyspaces  NEW_ROLE_HERE;
