There are a number of ways to do this, one way would be to:
i) Create a group eg. "internet users"
ii) add all users that you wish to allow internet access to that group
iii) create a policy to allow access to members of the "internet users" group 'only'
So when you want to stop someone from having access you will simply need to remove them from this group.
