I would say from a PS perspective that CAG/AAC is much more integrated than
any other product out there.  Unfortunately, that integration does not
involve the actual published applications.  It integrates from the
perspective of you can use the AAC filters to control what published
applications are seen from the web interface and what PS policies are
applied.  Nothing in AAC allows the sort of control that your looking for
from within a published application in regards to thing like UNC paths.  But
you'll notice that AAC filters can be used to assign PS policies so you
could control who gets client drive mappings, who gets printer autocreation,
etc.  This would allow you to control what leaves the network.

Guys Thanks for the responses. We want to restrict unc paths when you are within a Citrix published app. We only want to do this when a a user comes in via our Juniper box.

The reason for this is using Juniper we currently only use it to access
citrix published apps.  Of course we can 'publish' folders but could we then
get it to launch a citrix app?  Then we would have to restrict all access
when you were within say word within citrix.

Is a CAG/AAC more flexible than juniper and more easily integrated with
PS?  Any easy ways you can see on how to restrict access to some data and
make sure it never leaves our own network in conjunction with citrix apps?

 Well the original post doesn't give a lot detail but keep in mind that it
is possible to make PS use CAG/AAC so it can be done, i.e. distinguish
where the user is coming from and assign the rights accordingly.....

that is how I read it also which is why I keep specifying that, from
within the published application, CAG and/or AAC would not be of any help.
As well, I believe what Steve is saying is only available through CAG
standalone not with AAC but I may be wrong on that but I'm pretty sure I'm
not.   heh

I was referring to VPN mode, you can make specific CIFS shares available as resources.....

You can control UNC's from the NavUI but NOT from within published
applications.

Also, it can provide access to only specific UNC paths when used in VPN

AAC doesn't do anything with published apps outside of letting you control
what apps get published based on the AAC filters and applying Citrix
policies based on AAC filters.  It would not modify any sort of
functionality within the application itself.  You have misunderstood what I
was trying to say.



AAC can do checks but they are based on some sort of value.  For instance,
a version of McAfee or Firewall.  If those values change on the client side,
then you must also know the change has happened so you can adjust your EPA
scans.  Otherwise, the EPA's will fail and the users won't get access.

The way I was thinking of would be to redirect your users to different
citrix servers based on their source location. The sensitive users would be
directed to servers with an lmhosts file that 'blocked' the UNC by
overriding the source name's IP resolution.



messy mind.

The only way that I'm aware of to control that type of access through Presetnation Server is using AAC. You can then use the filters within AAC on your published applications.

I asumme this is if you are publishing folders on Juniper?  We publish
Citrix apps on Juniper only....So the control really needs to be within the
citrix session.



Further ideas?

 A Juniper device'll let you do it as well won't it? You can allow unc
access and then define roles that would allow access to those resources. You
could either allow full network browse access - or publish the folder
themselves iirc.

All



We are after a product that will allow us block sensitive unc's for
users.  This of course needs to differ depending on if the user is internal
or external.



When they are external they connect to Citrix via Juniper.  When they are
internal they use either normal desktops or Citrix.



I believe by using CAG with AAC we can do this.



Can anybody suggest any other software\hardware\methods that we could to
achieve this?
