Re: [Geoserver-users] Standalone Geowebcache and Geoserver Data Security Checks

[Steve Omondi]

A SecurityFilter that talks to a remote GeoServer is certainly possible if
someone wanted to write one, although it would lose some of the benefit of
caching since it would be going to the back end for a security check each
request.

​This would be great. It could be implemented with an option to force GWC
to go to the backend Geoserver and perform security check just like the
Integrated GWC​ with the *Enable Data Security*


*[image: Inline image 1]*

So depending on whether I choose to E*nable Data Security Checks *or not
then GWC can leverage the *SecurityFilter *for the Tilesets.

Kind regards,
Steve Omondi

The most recent stand alone GWC (1.12) has the notion of data security
(the new SecurityFilter extension point).  It just doesn't have anything
more than a notion as the only implementation of SecurityFilter so far
is in GeoServer. 

A SecurityFilter that talks to a remote GeoServer is certainly possible
if someone wanted to write one, although it would lose some of the
benefit of caching since it would be going to the back end for a
security check each request.

Thanks Andrea for the concise response.

I'll have to reconsider my options.

To the best of my knowledge, you don't. Security integration happens only
if you run GWC embedded in GeoServer,
a stand-alone GWC has no notion of security at all (can be developed of
course, but does not seem a trivial task).

[Geoserver-users] Standalone Geowebcache and Geoserver Data Security Checks

[Steve Omondi]

Hey guys,

I have multiple Geoserver Instances and one Standalone Geowebcache in front
of the Geoservers (via a HTTPD proxy load balancer - balancing requests to
the geoservers).

All the Geoservers are synchronized and have *Data Rules* restricting
access for different users to the different /workspaces/layergroups/layers.

Currently GWC seems not be able to access layers with rules.
Error Message on Tiles requests:
400: All backends (1) failed. Reason: Unexpected response code from
backend: 403 for http://ros-gs4:8082/geoserver/wms?. Last request: '
http://ros-gs4:8082/geoserver/wms?'.

I have to remove all the rules from Geoserver from *Data Security
before *Standalone
GWC is able to return the tiles. On the other side, ones tiles are seeded
they are accessible without need to authorization. This is not a desirable
behavior for me.

*How do I use GWC in front of multiple Geoservers with data security checks
(Rules) workin and perform Authorization for the layers being accessed and
the seeded tiles? How do I mage Stand alone GWC perform Data Security Check
like the Embedded GWC does?*

*Available help will be appriciated.*


Kind regards,
Steve Omondi
