The purpose of this paper is not how to secure computers but how to set up virtual tunnels to perform secure communication, whether sending documents or sending email. Business travelers should read Jim Purcell, Frank Reid, and Aaron Weissenfluh's articles on travel security. Home users with high-speed access should read Ted Tang's article for information on how to secure your computers with high-speed access. I'd recommend the many resources available on www.sans.org, www.securityfocus.com, or www.securityportal.com for tutorials on how to secure your computers and servers.
The way to ensure that sensitive data is transmitted securely and quickly is to use encrypted methods of data delivery. This can be by way of encrypted email, using secure web-based email services, or establishing encrypted tunnels between two computers. Also, easy to setup and reliable software need to be used in order to allow the inexperienced users the ability to quickly establish secure communication channels. Taten Ylonen 's Secure Shell and MindBright Technology's MindTerm are a quick, easy to use, and reliable solution for securing communication over the Internet.
