We have servers at an ISP and a firewall in place. At our main office, we have a VPN. For an added layer of security, I'm thinking a good model may be to have developers connect to the corporate VPN and then only allow traffic in to the servers through the firewall from the VPN's IP.
My questions:
1) Does this sound like a sound method for connection?
2) What is the best method for validating user at VPN? I've used a cryptocard in a previous environment, but I'm not real familiar with the technology or competitors.
Thanks, D
