In addition to an explosion of touch points, we are faced with an infinitively
complex and rapidly changing web of networks, applications, systems, client software,
and service providers. Under these circumstances, absolute security cannot be guaranteed
since it’s impossible to test the security implications of every configuration combination
of hardware and software under every set of conditions.
During the last year there has hardly been an issue of a computer or business
magazine not flooded with buzzwords like e-commerce, Internet,
Web, or security. E-commerce (electronic commerce) is a result of moving
the economy to a new medium, namely the computer network. For the
most part, interconnected networks all over the world use a common set of
protocols (i.e., TCP/IP), thus making up the Internet.
Multicast and group security (Artech house computer security series) is a handbook for engineers, architects and other practitioners working in the field of Internet security. It presents detailed coverage of security technologies and techniques for IP (Internet protocol) multicast networks from the leading developer of the standards. It also examines important security issues relating to other group communication technologies. Algorithms and protocols for multi-party secure communication are included.
There is an invisible elephant in this book: your application. And, it sits at the center of
every topic we touch in each chapter we present. This book is for systems architects
who are interested in building security into their applications. The book is designed to
be useful to architects in three ways: as an introduction to security architecture, as a
handbook on security issues for architecture review, and as a catalog of designs to look
for within a security product.

We use the term privacy when referring to the desire to keep communication from being seen
by anyone other than the intended recipients. Some people in the security community avoid the
term privacy because they feel its meaning has been corrupted to mean the right to know, because in
some countries there are laws known as privacy laws which state that citizens have the right to see
records kept about themselves. Privacy also tends to be used when referring to keeping personal
information about people from being collected and misused.

Secure communication is an increasingly important application of the Internet.
Without secure communication many existing social functions cannot beneﬁt from
modern technology. The primary example is commerce. The foundation of secure
communication is cryptography, which enables secure communication through the
use of keys. The management of these keys has proven to be a problem when the
technology is taken into use.
Using certiﬁcates also opens up for the possibility of removing the key transfer
between Alice and Bob completely! This is an important feature when secure
communication is being implemented between a large number of participants. This
is because none of Bob’s ability to trust the public key he receives now depends on
whether he is actually communicating with Alice or not. His ability to trust the key
depends solely upon his trust relationship with the trusted third party.
We are presently witnessing mergers and takeovers of unprecedented speed and extent be-tween companies once thought to have national identities, or at least clearly identifiablelines of products or services.
All email communications on the internet are possible by two protocols:
1) Simple Mail Transfer Protocol (SMTP port-25)
2) Post Office Protocol (POP port-110)
E-Mail hacking consists of various techniques as discussed below.The most effective and easiest way to trace an email is to analyze it's email headers. This can be done by just viewing the full header of received email.
In an age when our society relies so heavily on electronic communication, the need
for information security is imperative. Given the value and confidential nature of the
information that exists on today’s networks, CIOs are finding that an investment in
security is not only extremely beneficial but also absolutely necessary. Corporations
are realizing the need to create and enforce an information security policy.
Hello, in this module we are going to discuss wireless networking. Specifically, we'll take a look at
how wireless technology works, how it is commonly deployed, and the security issues associated
with using it. Because wireless communications can penetrate opaque objects such as buildings, the
risk of someone accessing a private network increases markedly. With wireless, an attacker does not
need to gain access to physical cables or jacks, but only needs to have an antenna and be within
range of the transmissions....
A Brief History of Security
“Well, I never heard it before,” said the Mock Turtle, “but it sounds uncommon
—Lewis Carroll, Alice in Wonderland.
Secret communication achieved by hiding the existence of a message is known as
steganography. The word is derived from the Greek word “steganos,” meaning cov-
ered and “graphin” meaning to write.
Over the last ten years, the impact of wireless communications on
the way we live and do business has been surpassed only by the impact
of the Internet. Cell phones, pagers, and wireless Personal Digital
Assistants (PDAs) have become so commonplace in our lives that it is
easy to forget that ten years ago, they were a rarity.
The only system which is truly secure is one which is switched off and unplugged, locked in a titanium lined safe, buried in a concrete bunker, and is surrounded by nerve gas and very highly paid armed guards. Even then, I wouldn’t stake my life on it….An open security model is the easiest to implement .
Simple passwords and server security become the foundation of this model.
If encryption is used, it is implemented by individual users or on servers.
