Integrating theory, research, and applications, this book examines the defense mechanisms and their role in both normal development and psychopathology. It describes how children and adults mobilize specific kinds of defenses to maintain their psychological equilibrium and preserve self-esteem, particularly in situations of trauma or stress.

Why Do I Do That? adapts the basic strategies of psychodynamic psychotherapy to a guided course in self-exploration, highlighting the universal role of defense mechanisms in warding off emotional pain. With easy-to-understand explanations, the first part teaches you about the unconscious mind and the role of psychological defenses in excluding difficult feelings from awareness. Individual chapters in the longer middle section explore the primary defense mechanisms one by one, with exercises to help you identify your own defenses at work. The final part offers guidance for how to "disarm" your defenses and cope more effectively with the unconscious feelings behind them. Psychological defense mechanisms are an inevitable and necessary part of the human experience; but when they become too pervasive or deeply entrenched, they may damage our personal relationships, restrict or distort our emotional lives and prevent us from behaving in ways that promote lasting self-esteem.

The idea that the human mind-that faculty of the intellect which we use to define and discern the truth-might also be used to deceive itself is not new. The classic orator Demosthenes warned of this possibility in 349 B.C. when he wrote that "Nothing is more easy than to deceive one's self; what a man wishes he generally believes to be true." 1 Even Jean Jacques Rousseau, who suggested the possibility of man as "noble savage," alerts us to this paradox, when he writes "Jamais fa nature ne nous trompe; c'est toujours nous qui nous trompons" ("Nature never deceives us; it is always we who deceive ourselves). 2 But it was Sigmund Freud who placed this idea firmly into the field of psychopathology and then, later, into a general psychological theory. According to Freud, understanding the function of a defense mechanism means not only fathoming the origin of pathological symptoms but also comprehending a model of the mind that includes both conscious and unconscious mental processes. From this initial focus on the general process of defense, Freud and his followers went on to identify various forms this process might take, with the result that today we have a list of 3 more than 37 defense mechanisms described in the literature.

What is the scientific status and the "truth value" of the concept of defense mechanisms? Among contemporary psychologists, three types of answers to this question may be expected. Some would wholeheartedly endorse the theoretical, clinical, and research value of this notion; others would reject it outright. Between these two extremes, a large number of observers, perhaps the majority, would suspend their judgment. Their attitude, compounded of hope and doubt, would capitalize on defense as an interesting and promising concept. At the same time, these psy chologists would express skepticism and disappointment over its clinical limitations, theoretical ambiguity, and research failures. The present volume is primarily addressed to the audience of hopeful skeptics-those who have not given up on the notion of defense, yet have been frustrated by the difficulties of incorporating it into the modern, streamlined structure of psychology. To this end, we have brought together theoretical and empirical contributions germane to defense together with reports about their applications to clinical and personality assessment, especially in relation to psychopathology, psychosomatics, and psycho therapeutic intervention.

`[The client material]... stimulated thought and reflection... Clark presented a large number of very tricky case studies and illustrated all manner of different and interesting ways of responding to clients who find it difficult to engage with the process of counselling. Furthermore, this is done in the framework of a model of counselling which integrates humanistic, psychodynamic and cognitive-behavioural theories in a most interesting and convincing way. In the end, I learned quite a lot and found myself pondering the case histories days later' - Counselling, The Journal of the British Association for Counselling The understanding of defence mechanisms is vital to counsellors and psychotherapists, particula

Not since Anna Freud's 1937 book, The Ego and the Mechanisms of Defense, has any one volume explored this topic as fully as Ego Mechanisms of Defense by George E. Vaillant. By summarizing the latest empirical studies, proposing a universal language of defense mechanisms, and demonstrating how various assessment methods can be used in diagnosis, case formulation, and treatment, Dr. Vaillant and an interdisciplinary group of contributors provide the groundwork for clinical practice as well as future research in the field.

Suddenly your Web server becomes unavailable. When you investigate, you realize that a flood of packets is surging into your network. You have just become one of the hundreds of thousands of victims of a denial-of-service attack, a pervasive and growing threat to the Internet. What do you do? Internet Denial of Service sheds light on a complex and fascinating form of computer attack that impacts the confidentiality, integrity, and availability of millions of computers worldwide. It tells the network administrator, corporate CTO, incident responder, and student how DDoS attacks are prepared and executed, how to think about DDoS, and how to arrange computer and network defenses. It also provides a suite of actions that can be taken before, during, and after an attack. Inside, you'll find comprehensive information on the following topics How denial-of-service attacks are waged How to improve your network's resilience to denial-of-service attacks What to do when you are involved in a denial-of-service attack The laws that apply to these attacks and their implications How often denial-of-service attacks occur, how strong they are, and the kinds of damage they can cause Real examples of denial-of-service attacks as experienced by the attacker, victim, and unwitting accomplices The authors' extensive experience in handling denial-of-service attacks and researching defense approaches is laid out clearly in practical, detailed terms.
