  • 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.

  • 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.

  • 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....

  • 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.
