This book looks at network security in a new and refreshing way. It guides readers step-by-step through the "stack" -- the seven layers of a network. Each chapter focuses on one layer of the stack along with the attacks, vulnerabilities, and exploits that can be found at that layer. The book even includes a chapter on the mythical eighth layer: The people layer. This book is designed to offer readers a deeper understanding of many common vulnerabilities and the ways in which attacker's exploit, manipulate, misuse, and abuse protocols and applications. The authors guide the readers through this process by using tools such as Ethereal (sniffer) and Snort (IDS). The sniffer is used to help readers understand how the protocols should work and what the various attacks are doing to break them. IDS is used to demonstrate the format of specific signatures and provide the reader with the skills needed to recognize and detect attacks when they occur. What makes this book unique is that it presents the material in a layer by layer approach which offers the readers a way to learn about exploits in a manner similar to which they most likely originally learned networking. This methodology makes this book a useful tool to not only security professionals but also for networking professionals, application programmers, and others. All of the primary protocols such as IP, ICMP, TCP are discussed but each from a security perspective. The authors convey the mindset of the attacker by examining how seemingly small flaws are often the catalyst of potential threats. The book considers the general kinds of things that may be monitored that would have alerted users of an attack.* Remember being a child and wanting to take something apart, like a phone, to see how it worked? This book is for you then as it details how specific hacker tools and techniques accomplish the things they do. * This book will not only give you knowledge of security tools but will provide you the ability to design more robust security solutions * Anyone can tell you what a tool does but this book shows you how the tool works

Using the semiotic theory of American philosopher Charles S. Peirce, Johansen applies psychoanalysis, psychology, literary hermeneutics, literary history, Habermasian communication, and discourse theory to literature, and, in the process, redefines it.

Attitudes and Persuasion provides an up-to-date overview of the crucial role that attitudes play in our everyday lives and how our thoughts and behaviour are influenced. The nature, function and origins of attitudes are examined, and a review of how they can be measured is given. The book addresses complex questions such as whether we always behave in accordance with our attitudes and what factors may influence us to change them.

The events of 11 September 2001 have led to significant developments in international law with respect to combating terrorism by military and non-military action. The volume addresses the issues raised in a comprehensive manner. It comprises country-reports with analyses of the developments in a number of selected countries. Based on these country-reports the volume traces new developments in the definition of international terrorism, deals with the issue of human rights protection under new anti-terrorist legislation and examines the recent developments towards international military action against terrorism.
