Re: [AG-TECH] AG security and multicast ?

You might want to take a look at what inSORS does with their venues, where the "room" can be assigned a "key" you need to unlock the door.

I think allowing anyone into a secure meeting until you "lock the
door" is a poor security model.  No need to lock the door and be
worried about who you have already let in, because it is really not
that user unfriendly to have an attendee list and add them to a secure
room with the GUI server administration tool.  If you don't do
security properly, it is just another hoop someone has to jump through
to get what you don't want them to have.

Something I've been asked about that's security related is about having the ability to 'lock' a room from within the venue client, akin to having a closed and locked door for a real conference room. Then, if the room were set up to encrypt the traffic and people couldn't just 'jump-in' it might make private meetings more attractive to those that have a need for it. Sure you can set up a room with allowing certain certificates, but that's cumbersome to have to do on a per-meeting basis if all you want is something like a bunch of 'conference rooms'. Having to have an operator tailor a room to a particular meeting isn't a very user-friendly way of doing it.
I asked a while ago on the list of a good way to do that and the response was it'd be something I'd have to do myself. If enough people think it's a feature they want, maybe we can convince the AG software writers/maintainers to add functionality?

Here are two good resources:

I get asked about security more and more now.  People are concerned that
their research will be broadcast to anyone with a multicast-enabled
network.  VIC and RAT do offer encryption keys, and that is an option
to enable with AGTk venue servers.  Rooms can have access based on
your globus certificates, too.  And AGTK uses SSL for its
client/server connections.


Would it be feasible to route multicast though a VPN for very secure
meetings?  Say, run a VPN server on the same machine that the venue
server is on, have clients connect their VPN client to it, and then
fire up AG over the encrypted tunnel?

Hello everybody,

As part of our distance learning project, we need in-depth technical information about security mechanisms and multicast allocation in the AG. Are there any documents or papers about this?

The team will be doing low-level implementation, so we need hard-core documentation for techies :o)

Thanks,

Dio.-
