I have two seperate networks in a data center each with their own internet connection. Network A has many users behind the firewall as well as many servers. There is a server that currently process CC transactions. Network A is set up with an ASA 5520.
Network B will have a server that provides a web interface for outside users to go to so they can put their CC information in and this webserver will need to communicate with the CC transaction server on Network A. Network B is set up with an ASA 5510.
Would a site to site VPN between the two servers be a secure way to accomplish this?
