"There is a good reason why people write superficial messages on post cards: post cards afford no confidentiality and there is no expectation of privacy. The Internet can be compared to a post card; it is one large system where data is freely interchanged. While common sense tells us that post cards are open to the public, there is a misperception among non-technical Internet users that Internet data is kept private. However, nothing could be further from the truth; on the Wild West net, all data is inherently open and unregulated."
"There are solutions to this predicament. One solution is called SSH (Secure Shell). SSH provides a way to take that "postcard" and have it securely delivered by a courier."
"But the truth is that the need for privacy and security on today's networks is far too important to be encapsulated in two bullets. This book is so loaded with valuable and important information that anyone using or administering SSH should read it thoroughly."
