Hello. We have a network of costumers with 2 mb links over ethernet and over VPN too. They can see our windows servers ( they have to ) to connect to our services. The question now is: If they are using M.S windows clients ( hosts ) that are connected to the internet, are they dangerous to our network ? Beside filtering traffic, to only give access to certain hosts what more do you recommend ? The servers are windows too. Are we in danger because of the possible infections of our costumers Â¿? What is the beet approach to this ?
