Blueprint for Authentication, Authorization & Accounting
Authentication is the act of establishing or confirming someone's identity.
Authorization is the concept of allowing access to resources only to those permitted to use them.
Accounting refers to the tracking of user actions - an audit trail.
SahanaPy currently authenticates on email address/password.
- this is the T2 method.
The default configuration is that Self-Registration is enabled.
This can be easily disabled via a single setting in the s3_setting table.
The email address is currently not verified.
- this should be fixed.
Sahana2 supports OpenID (as does Launchpad), so that would be good to support & looks easy:
We want to be able to provide a simple way of setting the overall security policy - allowing for flexible deployment options.
- Anonymous access is granted for all Read operations, with Create/Update/Delete requiring a user to be Authenticated
- Anonymous access isn't granted for anything - all access requires a user to be Authenticated
- Modules able to be restricted by Role membership
- Tables able to be restricted by Role membership
- C/R/U/D permissions distinct
- Records able to be restricted by Role membership
- C/R/U/D permissions distinct

- Current Stable: http://wiki.sahana.lk/doku.php?id=dev:security
- Old: http://wiki.sahana.lk/doku.php?id=dev:authorization
(NB The Vol module currently uses a separate method)
We also want to look at linking the AAA t2_person table with the Person Registry's person table
S3 builds on the default T2 AAA system:
Anonymous access is currently granted for all Read operations, with Create/Update/Delete requiring a user to be Authenticated:
- T2 can extend this by protecting resources with
t2.have_membership()(table level security which can be separated for C/R/U/D) &
- we should probably support these by adding hooks into the RESTlike controller
User maintenance can be done via appadmin until we develop our own UI.
t2_group table for Contact Lists information
s3_role table for Security access
- roles initialised in
- module writers need to add any required roles there
Membership of roles is controlled via the Many-to-Many table:
T3 defines a simple
t2.is_admin defined in
is_admin=(t2.logged_in and (not settings.administrator_emails or t2.person_email in settings.administrator_emails)) t2.is_admin=is_admin
- Function components protected with:
if not is_admin: t2.redirect('index',flash=T('Not Authorised'))
- appadmin protected in the same way :)

- Zope uses:
STATUS: Complete apart from needing to get new_values back from the form after processing
Events can be audited at the Global level or the per-Module level.
Most auditing wins, so if the Global is True, then all Modules will Log. If Global is False then Modules have control & can selectively enable it.
Global settings are defined in
Per-Module settings are defined in
Each defines 2 levels of Auditing - Audit just Changes (C/U/D), or also Reads:
These are passed to the session for use in controllers/displays:
They are enforced via the RESTlike controller
For now this is configured via appadmin, although we should later make a nicer UI which has a single checkbox for 'Enable Auditing'. This then opens up a two checkboxes:
If each is ticked, this sets the
audit_write & opens up an extra checkbox for 'Enable Auditing of Reads' (sets
