We have to balance the needs of our users and the need to provide a secure
network.  The major applications (300+) we package and distribute on a as
needed basis to our users.  The problem is the applications that < 10 users
want to install.  We do not want to deploy very minor software applications
through our application deployment framework (Radia) that only a few users
require because the engineering time required to make sure that this minor
app is compatible with the 300 other apps is considerable.  If the user
installs the software and breaks the machine we will reimage it back and
redeploy the managed apps to it.

It is all we can do right now to maintain our managed application pool as it
is now.  The thought of having to manage every single app gives me the
shivers.

It is not a perfect solution for a secure network but unfortunately is one
we are being forced to work/live in.

Users must be able to install whatever nefarious software they want, but you
still want a secure network? I think those goals are mutually exclusive,
especially if you factor in a reasonable amount of social engineering.

For software installations requiring admin access, you could try to install
it through the group policies.

Sorry for the repost but I submitted this to 2 lists and did not get any
responses.

If you have any suggestions please throw them out.

Thanks in advance

Subject: [ActiveDir] User rights on Domain computers and security issues

We are in the process of rolling out an new desktop at MUSC using a W2K AD
infrastructure and an XP SP1 managed desktop.

We piloted out new desktop for about a month to gauge the user's
requirements for the new system.  We had made the users domain account a
member of the local power users group and enable roaming profiles.  During
out pilot testing the user base requested the ability to install hardware
devices (zip drives, biometric mouse ect) and be able to install any
software they want to locally.  The power user's right gave them the ability
to install most hardware devices EXCEPT devices that required a service to
be installed or needed to modify certain hives under HKLM.  The power user's
right also gave them the ability to install most software EXCEPT if
installation required local administrator privileges (like MS Project 2000).

Giving the user account local administrator privileges is not an option for
the security concerns that are enumerated here:

http://www.sans.org/rr/win/commonality.php

Also giving the users local administrator access would allow them to browse
other users local profile directories that had been cached.  Although we
could delete all profiles upon log off this would prevent the user from
logging onto the computer in the event of a network failure (there are no
local user accounts).

We tried to give the local power user's group full control to HKLM.  The
trouble with this is that in essence it makes them local administrators on
the machine which bring us back to our security concerns.

Any ideas....all suggestion are welcome.
