The flight from Lihue to San Francisco is about five and a half hours and allows me some of my most productive work time. The phone doesn't ring, the dog doesn't ask to go outside, and my personal firewall doesn't start blinking because someone is trying to scan my computer. The flight attendant crews are starting to know me; I don't want any airplane food, I brought my own recycled water bottle filled with water from my own reverse osmosis filter, just let me write. I am very thankful for a bit of understanding from the crew of United FLT 30 for the time to write this preface. If any of my words give you insight into the current state of affairs with perimeter and internal network management, don't attribute that to me. I rely more each day of my life on the words in James 1:5; I am just the messenger.
I was enjoying working on the second edition of this book when a scene on the airplane entertainment televisions caught my eye. It was a video history of United Airlines, which started by delivering airmail in rickety old airplanes with exposed cockpits. Today, modern, fast, sophisticated aircraft have an incredible safety record. The airline industry has gone from an odditya great tool to entertain the crowds at county fairsto an industry that is crucial to our way of life and economy. The airlines in the United States were essentially grounded for about three days following the terrorist attacks of September 11, 2001. The U.S. Congress debated whether to give the airlines money; they decided against it and United is now in chapter 11.
By exploring what has changed in the airline world, you will see both the past and the future of our industry, information technology (IT). Like the airline industry, IT has historically been accomplished on rickety platforms. We have benefited from rapid advances in technology. We have seen a decline in personal service. We are headed for continuous inspections, a defense-in-depth approach, and we are every bit as vulnerable and at the same time crucial to the economy.
