How to best manage AD groups, users, roles and index access?

Jamie

Hello.

I have two indexes and three users.  Each user is in specific AD group.  Each group is mapped to a respective role.  Each role gives access to a specific index(es).

user_a can only search index_a, user_b only index_b and user_c can search both.  Restricting access to indexes is important.

Indexes
index_a
index_b

AD group
user_idx_a (user_a is a member)
user_idx_b (user_b is a member)
user_idx_all (user_c is a member)

Users and roles
user_a has role role_a
user_b has role role_b
user_c has role role_c

authorize.conf

[role_role_a]
importRoles = user
srchIndexesDefault = index_a
srchIndexesDisallowed = index_b

[role_role_b]
importRoles = user
srchIndexesDefault = index_b
srchIndexesDisallowed = inbex_a

[role_role_c]
importRoles = user

That's all fine. But as more indexes are added, I wonder how this will scale, especially where, for example, user_d needs access to newly created index_d, plus say index_a.  I will now need a new AD group (user_idx_d), a new role (role_role_a_d) and a suitable entry in authorize.conf

I've gained some mileage from putting index restrictions on the inherited (user) role.  For example:

[role_user]
srchIndexesDisallowed = main;splunklogger;summary

I had thought I would put users in multiple AD groups, but whilst membership brings a new role / index, it also means I end up with conflicting 'disallowed' directives.

Is there a better way?  Or have I reduced the administration to the minimum whilst maintaining index access granularity?

Many thanks.

Hi, 

My company also faced the same issue. Splunk have a very restricted way of doing RBAC. Until now they do not have any fixes on this. Do you have any luck on this thus far? 

Regards,

Anton
