What is the difference between security with a dial-up and security with a T1 connection. I want a computer in an outside office to be able to access our server. At present it uses a dial-up and I was going to install PCAnywhere on the computer for communication. Security is a must. If I was going to get a T1 connection I was going to setup a VPN. I would like to know how & why, not just a T1 is more secure.
