´´Hacking´´ ist die Kunst, kreativ Probleme zu lösen - vom Entwickeln einer unkonventionellen Programmierlösung bis hin zum Aufdecken von Sicherheitslöchern in einem schlampig entworfenen Programm. Viele Menschen bezeichnen sich als Hacker, aber nur wenige besitzen das eigentlich notwendige Hintergrundwissen. Jon Erickson zeigt nicht, wie man sich existierende Exploits beschafft und diese einsetzt, sondern vermittelt detailliert, wie Hacking-Techniken und Exploits tatsächlich funktionieren. Dazu führt er aus einer Hacker-Perspektive in die Grundlagen der Programmiersprache C ein und erklärt die wesentlichen Aspekte der Computersicherheit in den drei eng zusammenhängenden Bereichen Programmierung, Vernetzung und Kryptografie. Mit der beiliegenden Live-CD und den darauf enthaltenen Beispielen können Sie die neu erworbenen Kenntnisse auch gleich praktisch anwenden. Nach der Lektüre werden Sie u.a. verstehen: - wie man in C, Assembler und mit Shell-Skripten programmiert, - wie manden Hauptspeicher durch Buffer Overflows und Format-String-Angriffe korrumpiert, - wie man Prozessor-Register und Hauptspeicher mit einem Debugger untersucht und so die Programmabläufe nachvollzieht, - wie man gängige Sicherheitsbarrieren - z.B. Intrusion-Detection-Systeme - überlistet, - wie man sich mit Port-Binding Zugang zu fremden Servern verschafft, - wie man Netzwerkverkehr umleitet und TCP-Verbindungen übernimmt. Mit der beiliegenden Live-CD und den darauf enthaltenen Beispielen können Sie die neu erworbenen Kenntnisse gleich praktisch anwenden. In der zweiten Auflage wurden alle Kapitel aktualisiert und erweitert, insbesondere die Einführung in die grundlegenden Funktionsweise eines Computers.

ggf. zzgl. Versand

This modern treatment of computer vision focuses on learning and inference in probabilistic models as a unifying theme. It shows how to use training data to learn the relationships between the observed image data and the aspects of the world that we wish to estimate, such as the 3D structure or the object class, and how to exploit these relationships to make new inferences about the world from new image data. With minimal prerequisites, the book starts from the basics of probability and model fitting and works up to real examples that the reader can implement and modify to build useful vision systems. Primarily meant for advanced undergraduate and graduate students, the detailed methodological presentation will also be useful for practitioners of computer vision. - Covers cutting-edge techniques, including graph cuts, machine learning and multiple view geometry - A unified approach shows the common basis for solutions of important computer vision problems, such as camera calibration, face recognition and object tracking - More than 70 algorithms are described in sufficient detail to implement - More than 350 full-color illustrations amplify the text - The treatment is self-contained, including all of the background mathematics - Additional resources at www.computervisionmodels.com

Privileged Attack Vectors
€ 21.99 *
ggf. zzgl. Versand

See how privileges, passwords, vulnerabilities, and exploits can be leveraged as an attack vector and breach any organization. Cyber attacks continue to increase in volume and sophistication. It is not a matter of if , but when your organization will be breached. Attackers target the perimeter network, but in recent years have refocused their efforts on the path of least resistance: users and their privileges. In decades past an entire enterprise might be sufficiently managed through just a handful of credentials. Today´s environmental complexity means privileged credentials are needed for a multitude of different account types (from domain admin and sysadmin to workstations with admin rights), operating systems (Windows, Unix, Linux, etc.), directory services, databases, applications, cloud instances, networking hardware, Internet of Things (IoT), social media, and more. When unmanaged, these privileged credentials pose a significant threat from external hackers and insider threats. There is not one silver bullet to provide the protection you need against all vectors and stages of an attack. And while some new and innovative solutions will help protect against or detect the initial infection, they are not guaranteed to stop 100% of malicious activity. The volume and frequency of privilege-based attacks continues to increase and test the limits of existing security controls and solution implementations. Privileged Attack Vector s details the risks associated with poor privilege management, the techniques that hackers and insiders leverage, and the defensive measures that organizations must adopt to protect against a breach, protect against lateral movement, and improve the ability to detect hacker activity or insider threats in order to mitigate the impact. What You´ll Learn Know how identities, credentials, passwords, and exploits can be leveraged to escalate privileges during an attack Implement defensive and auditing strategies to mitigate the threats and risk Understand a 12-step privileged account management Implementation plan Consider deployment and scope, including risk, auditing, regulations, and oversight solutions Who This Book Is For Security management professionals, new security professionals, and auditors looking to understand and solve privileged escalation threats

Architecture-Based Design of Multi-Agent Systems
€ 72.99 *
ggf. zzgl. Versand

Multi-agent systems are claimed to be especially suited to the development of software systems that are decentralized, can deal flexibly with dynamic conditions, and are open to system components that come and go. This is why they are used in domains such as manufacturing control, automated vehicles, and e-commerce markets. Danny Weyns´ book is organized according to the postulate that ´´developing multi-agent systems is 95% software engineering and 5% multi-agent systems theory.´´ He presents a software engineering approach for multi-agent systems that is heavily based on software architecture - with, for example, tailored patterns such as ´´situated agent´´, ´´virtual environment´´, and ´´selective perception´´ - and on middleware for distributed coordination - with programming abstractions such as ´´views´´ and ´´roles.´´ Next he shows the feasibility and applicability of this approach with the development of an automated transportation system consisting of a number of automatic guided vehicles transporting loads in an industrial setting. Weyns puts the development of multi-agent systems into a larger perspective with traditional software engineering approaches. With this, he opens up opportunities to exploit the body of knowledge developed in the multi-agent systems community to tackle some of the difficult challenges of modern-day software systems, such as decentralized control, location-awareness, self-adaption, and large-scale. Thus his book is of interest for both researchers and industrial software engineers who develop applications in areas such as distributed control systems and mobile applications where such requirements are of crucial importance.

Introduction to Computer Security: Pearson New ...
€ 48.99 *
ggf. zzgl. Versand

For computer-security courses that are taught at the undergraduate level and that have as their sole prerequisites an introductory computer science sequence (e.g., CS 1/CS 2). A new Computer Security textbook for a new generation of IT professionals. Unlike most other computer security textbooks available today, Introduction to Computer Security, 1e does NOT focus on the mathematical and computational foundations of security, and it does not assume an extensive background in computer science. Instead it looks at the systems, technology, management, and policy side of security, and offers students fundamental security concepts and a working knowledge of threats and countermeasures with ?just-enough? background in computer science. The result is a presentation of the material that is accessible to students of all levels. Features + Benefits Accessible to the general-knowledge reader. Authors Goodrich and Tamassia recognize that prerequisites for an extensive background in CS and mathematics are not only unnecessary for learning but also arguably contribute to a reduction in enrollments and a shortage of computer-security experts. Therefore, the authors assume only the most basic of prerequisite knowledge in computing, making this text suitable for beginning computer science majors, as well as computer science minors and non-majors. Teaches general principles of computer security from an applied viewpoint. In this new text, the authors cover specific computer security topics while providing necessary material on the foundations of computing needed to understand these topics. As a result, students learn about vital computer security topics such as access control, firewalls, and viruses as well as a variety of fundamental computer-science concepts like algorithms, operating systems, networking, and programming languages. Topics covered include: o Common cyberattacks including viruses, worms, Trojan horses, password crackers, keystroke loggers, denial of service, spoofing, and phishing. o Techniques for identifying and patching vulnerabilities in machines and networks as well methods for detecting and repairing infected systems. o Fundamental building blocks of secure systems such as encryption, fingerprints, digital signatures and basic cryptographic protocols. o Human and social aspects of computer security, including usability, interfaces, copyright, digital rights management, social engineering, and ethical issues. A practical introduction that will prepare students for careers in a variety of fields. This text encourages students to think about security issues and to deploy security mechanisms early in designing software applications or in making software purchase/ deployment decisions. This skill will be appreciated by future employers--who may include corporations in the financial, healthcare and technology sectors--for whom the security of software applications is a critical requirement. The material in the text will also provide readers with a clear understanding of the security ramifications of using computers and the Internet in their daily lives (e.g., for online banking and shopping), as well as the potential threats to individual privacy (as seen in recent debates on electronic voting, for example), and possibly to democracy itself, that may arise from inappropriate use of computer security technology. Projects The authors provide a collection of creative, hands-on projects at three levels of difficulty that can be used both in computer security and computer security-related courses. A wide set of options will allow instructors to customize the projects to suit a variety of learning modes and lab resources. In each project, students are given a realistic, though simplified, version of a working system with multiple vulnerabilities and a list of allowed attack vectors. They may be asked to work in ?break-it? mode, which will require students to attack a system by developing exploits that take advantage of the discovered vulnerabilities, or they may be asked to work in ?fix-it? mode in which the student hardens the system by developing mechanisms for removing or mitigating the vulnerabilities. SUPPLEMENTS A collection of slide presentations created by the authors each suitable for a one-hour lecture, covering all the course topics. The presentations will include links to relevant resources on the web and will have extensive notes. The slide presentations have been created in a standard file format compatible
