There will often be a want to give clients private and sensitive data from an Internet dependent Web Server & software. Historically all of this logic has resided on the internet server, but there are new ways to disconnect the Net from your sensitive information and still give the client what they want. 1 great way to protect your Net web site is to eradicate all of the enterprise logic from the internet site and count on a corporate web service that is further back again behind the firewall security level.

Your consumer website that is searching for a equilibrium, now asks a straightforward question to the net service, and provides the response. There are a whole lot of other methods - largely authentication and protection connected, but bottom line is that all of the private and enterprise essential data has been removed from that exposed internet server.
