Tomorrow, all communications will happen over IP. In the past, telecom operators handled most communications, and the main business for them was voice communication. In reality, almost all last-mile communications today still happen over the conventional telecom infrastructure. The backbone of the Internet has been going through a fast transition to faster and faster fiber optics and digital data transfer. The era of analog communications has been over for some time already.
Today, people speak of Voice over IP, but a better name for the Next Generation Networks is Everything over IP (EoIP). And all of that communication will be wireless. But what does that have to do with the topic of this book? It means the world has to finally wake up to the security of the communications networks.
To be secure, you have to understand that wireless networks are always open. While in traditional telephone networks all the switches were kept behind locked doors and all the cabling was protected, in wireless technology there are no cables and everyone has access to wireless access points. One compromised infrastructure component, and the entire network is compromised. One virus-contaminated access device, and everyone in the network will be contaminated.

Job titles like "Technical Architect" and "Chief Architect" nowadays abound in the software industry, yet many people suspect that "architecture" is one of the most overused and least understood terms in professional software development.
Gorton's book helps resolve this predicament. It concisely describes the essential elements of knowledge and key skills required to be a software architect. The explanations encompass the essentials of architecture thinking, practices, and supporting technologies. They range from a general understanding of software structure and quality attributes, through technical issues like middleware components and documentation techniques, to emerging technologies like model-driven architecture, software product lines, aspect-oriented design, service-oriented architectures, and the Semantic Web, all of which will influence future software system architectures.
All approaches are illustrated by an ongoing real-world example. So if you work as an architect or senior designer (or want to someday), or if you are a student in software engineering, here is a valuable and yet approachable source of knowledge.
"Ian's book helps us to head in the right direction through the various techniques and approaches… An essential guide to computer science students as well as developers and IT professionals who aspire to become an IT architect". (Anna Liu, Architect Advisor, Microsoft Australia).
