We have a new product requirement that needs two PCs on ADSL or 56k dial-up (Dynamic IP) to access each other's data and communicate. Security is required to stop unauthorized access and hacking.
Could you recommend a solution for the above and what would be required (in terms of resources) and what would be the limitations of any solution?
You have couple of options.
If either of the site has a VPN infrastructure in place - it will be the best option. The other site can use a VPN client to connect and communicate securely.
If it's going to be a PC to PC communication, there are communication software's which enable encryption over any communication channel, be it a dial-up. You can also use SSH, SFTP etc.
Access and Terminal servers are the other good options. They allow multi-level client authentication which allows clients to dial-in into any TCP/IP network and communicate securely. It delivers security with CHAP, PAP, dial-back support and multi-level password protection.
With ADSL, you can use a Personal/Mid range Firewall which can be configured to allow communications only from trusted sites and on specific ports.
