However, in the last 10 years, security “disasters” have challenged the design and development of networks and systems. Vulnerabilities in current systems are frequently exploited by hackers and attackers. Cyber attacks have become a more and more serious threat to our society. In order to better protect networks, this article gives an overview on a variety of hacking techniques. This article focuses on the objectives, principles, functionalities and characteristics of different types of hacking techniques in wired networks, and provides in-depth discussions on the common characteristics of cyber attacks, the structure and components of cyber attacks, and the relationships among cyber attacks. These discussions can help security professionals grasp the “soul” of a “new” cyber attack in an easier and quicker way. INTRODUCTION Nowadays, wired networks, especially the Internet, have already become a platform to support not only high-speed data communication, but also powerful distributed computing for a variety of personal and business processes every day.
