The emergence of the hominids, more than five million years ago, marked the start of the human odyssey through space and time. This book deals with the last stage of this fascinating journey: the exploration of cyberspace and cybertime. Through the rapid global implementation of information and communication technologies, a new realm for human experience and imagination has been disclosed. Reversely, these postgeographical and posthistorical technologies have started to colonize our bodies and minds. Taking Homer's Odyssey and Kubrick's 2001: A Space Odyssey as his starting point, the author investigates the 'informatization of the world-view', focusing on its implications for our culture – arts, religion, and science – and, ultimately, our form of life. Moving across a wide range of disciplines, varying from philosophical anthropology and palaeontology to information theory, and from astrophysics to literary, film and new media studies, the author discusses our 'cyberspace odyssey' from a reflective position beyond euphoria and nostalgia. His analysis is as profound as nuanced and deals with issues that will be high on the agenda for many decades to come. In 2003 a Dutch Edition of Cyberspace Odyssey received the Socrates Prize for the best philosophy book published in Dutch.
Botnet is most widespread and occurs commonly in today‘s cyber attacks, resulting in serious threats to our network assets and organization’s properties. Botnets are collections of compromised computers (Bots) which are remotely controlled by its originator (BotMaster) under a common Command-and-Control (C&C) infrastructure. They are used to distribute commands to the Bots for malicious activities such as distributed denial-of-service (DDoS) attacks, spam and phishing. Most of the existing Botnet detection approaches concentrate only on particular Botnet command and control (C&C) protocols (e.g.,IRC,HTTP) and structures (e.g., centralized), and can become ineffective as Botnets change their structure and C&C techniques. In this book at first we provide taxonomy of Botnets C&C channels and evaluate well-known protocols which are being used in each of them. Then we proposed a new general detection framework which currently focuses on P2P based and IRC based Botnets. This proposed framework is based on definition of Botnets. Botnet has been defined as a group of bots that perform similar communication and malicious activity patterns within the same Botnet.
The book describes about the threats on the database.we provide descriptions and examples of how attacks of different type could be performed. we also present a methodology to prevent SQL injection attacks. It concentrate on the SQL queries and SQL Stored procedure where Input parameters are injected by the attacker.SQL injection refers to a class of code-injection attacks in which data provided by the user is included in an SQL query in such a way that part of the user’s input is treated as SQL code.Even if the injected code is intercepted before execution, administrators are often presented with information that does not identify clearly the association between the commands that were attempted, the assets that were at risk, the threats that were imposed, and the countermeasures he/she has at disposal. To address these issues, a repository of SQL injection attacks that are classified in a semantic-aware, easy to comprehend model is needed.
Neil Postman is one of the most level-headed analysts of education, media, and technology, and in this book he spells out the increasing dependence upon technology, numerical quantification, and misappropriation of "Scientism" to all human affairs. No simple technophobe, Postman argues insightfully and writes with a stylistic flair, profound sense of humor, and love of language increasingly rare in our hastily scribbled e-mail-saturated world.
In land, sea, and air battles, military combatants can see the enemy coming, whether it's the whites of their eyes or a blip on a screen. International boundaries easily define when an aggressor threatens the sovereignty of a nation, giving the victim nation the right of jurisdiction, and there are specific international laws that address military operations in space. In addition, the international community has defined when an adversary's use of force threatens a nation's territorial integrity and political independence. However, the global nature of cyberspace and the speed of which victims can experience cyber attacks force nations to deal with the legal challenges associated with over-the-horizon military operations.
