“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.“
