These are the two methods that come to mind...like everything else in linux, there are
a hundred other ways to accomplish the same task.
One method would be to diplay in a user's menu only those apps that you wish them to
run. This is accomplished differently for each different WindowManager (which one are
you using?). This method is fairly easy to maintain. However, this does not prevent a
user from opening a shell and typing 'netscape' or whatever to run the app unless of
course you don't give them a shell menu option.
You could create one or more groups and change ownership and permissions of the
various apps so that only users in the group can run the app.
For example, if you wanted to limit who could run 'netscape':
1. Create a group called 'netscape' or 'station_a' or whatever
2. change group ownership of /usr/bin/netscape chgrp groupname /usr/bin/netscape
3. Change permissions of /usr/bin/netscape: chmod 754 /usr/bin/netscape
4. Add users to the group that need to run the app
This way becomes a huge adminstrative task if you have alot of apps to lock down but
with some thought, you could figure out a quick/easy way to do it.
