diffrent way of securing a subnet! Please help

["Héroux, Christian" <Christian.Heroux () etsmtl ca>]

Hello All!
        I need to secure a subnet and restrict access to certain users. I have been looking at different way to do it 
and I didn`t find many real way to do it just some concept. Here the solution I found on the net:

1- Access-list on the interface of that subnet. Very difficult to manager and limite allowed user to use a specific 
workstation or vlan.
2- Cisco Pix firewall. Too expensive not justifiable for the projet
3- Remote access software. Which one is really secure? PCanywhere, VNC, terminal server
4- Authentication base proxy. Novell borderManager seem to do the job, squid also seem to do it. Any other that can be 
link to an active directory
5- VPN software peer to peer. Microsoft has a solution.

I also read about  role base access control (RBAC) but it seem to be implemented in the OS not as a stand alone 
software or in router. Am I right? Where is the official web page for squid?
