This book provides you with comprehensive knowledge about Linux Security. The book is aimed at readers who are familiar with Linux concepts but now want to gain a solid foundation in Linux security features. It is assumed these readers already understand some Linux and networking concepts, such as network protocols, network servers, and so on. This book contains detailed information to help you fortify your Linux environment and provides questions that enable you to check your understanding at the end of key chapters.

Chapters 1 through 5 cover security basics in the Linux environment. These chapters give you an overview of Linux security, covering the precautions to be taken while installing and administering Linux. This part of the book also gives you an overview of the various authentication and encryption techniques you can use to protect your data.

Chapters 6 through 9 deal with securing networks in the Linux environment. Various kinds of possible network attacks are discussed in this part of the book, and you are given guidelines for preventing these attacks. Securing network servers—such as Apache Web server, FTP server, Sendmail, DNS, and SAMBA—is the core of this second part of the book.

Chapters 10 through 13 focus on preventing intrusion and data recovery. In these chapters, you are provided with an extensive list of signs of intrusions. You will learn to use various tools and security utilities to detect and avoid intrusion.

Maintaining logs regularly is a good practice for system administrators. Logs can give you indications of methods used to attack your system, and at times, you can get information about the attacker as well. Chapter 12, “System Logs,”educates you about using logs. In the last chapter of the book, I discuss the importance of making backups. You’ll realize how important backups are if you ever lose data due to system crashes or other reasons. Various commercial and non-commercial tools that you can use to maintain backups are discussed in this chapter.

Finally, this book also includes several appendices. The appendices include best Linux practices and FAQs for Linux security. An appendix on the future of Linux also is included at the end of the book.

"Michael has unquestionable knowledge about how organizations today are linking their systems across enterprise-wide networks and virtual private networks (VPNs), as well as increasing their exposure to customers, competitors, browsers, hackers, and physical threats to the facility equipment and network(s). This book will show you how each connection magnifies the vulnerability to attack. This book also provides the fundamental knowledge you need to analyze electronic and physical risks to your networks and systems." John Vacca, Author of numerous computer security books

The physical security of IT, network, and telecommunications assets is equally as important as cyber security. We justifiably fear the hacker, the virus writer and the cyber terrorist. But the disgruntled employee, the thief, the vandal, the corporate foe, and yes, the terrorist can easily cripple an organization by doing physical damage to IT assets. In many cases such damage can be far more difficult to recover from than a hack attack or malicious code incident. It does little good to have great computer security if wiring closets are easily accessible or individuals can readily walk into an office and sit down at a computer and gain access to systems and applications.

Even though the skill level required to hack systems and write viruses is becoming widespread, the skill required to wield an ax, hammer, or fire hose and do thousands of dollars in damage is even more common. Although many books cover computer security from one perspective or another, they do not thoroughly address physical security. This book shows organizations how to design and implement physical security plans. It provides practical, easy-to-understand and readily usable advice to help organizations to improve physical security for IT, network, and telecommunications assets.

This book provides:

* Expert advice on identifying physical security needs
* Guidance on how to design and implement security plans to prevent the physical destruction of, or tampering with computers, network equipment, and telecommunications systems
* Explanation of the processes for establishing a physical IT security function
* Step-by-step instructions on how to accomplish physical security objectives
* Illustrations of the major elements of a physical IT security plan
* Specific guidance on how to develop and document physical security methods and procedures

"What I really like about this book is that it cuts through the vast amount of noise about QoS in the Internet, and pulls out the core ideas (integrated and differentiated services, MPLS, and traffic engineering) in plain and simple technical prose. Internet QoS presents a balanced view of the various technologies and relates them to their practical use. It's up to date, but unlikely to go out of date quickly either, so should prove useful to engineers and students alike."

--Jon Crowcroft, University College London

Guaranteeing performance and prioritizing data across the Internet may seem nearly impossible because of an increasing number of variables that can affect and undermine service. But if you're involved in developing and implementing streaming video or voice, or other time-sensitive Internet applications, you understand exactly what's at stake in establishing Quality of Service (QoS) and recognize the benefits it will bring to your company.

What you need is a reliable guide to the latest QoS techniques that addresses the Internet's special challenges. Internet QoS is it-the first book to dig deep into the issues that affect your ability to provide performance and prioritization guarantees to your customers and users! This book gives a comprehensive view of key technologies and discusses various analytical techniques to help you get the most out of network resources as you strive to make, and adhere to, meaningful QoS guarantees.

Features

• Includes valuable insights from a Bell Labs engineer with 14 years of experience in data networking and Internet protocol design.
  
• Details the enhancements to current Internet architectures and discusses new mechanisms and network management capabilities that QoS will require.

Networking technologies and concepts are often difficult to explain, even through careful description and well thought out examples. One method for making this information "stick" is done by creating an environment where networking professionals and students can visualize how networks work, utilizing a software tool that simulates the functions within a network. The tool itself is highly useful in that it provides a virtual environment for an assortment of desirable features such as modeling a network based on specified criteria and predicting its performance.

The Network Simulation Experiments Manual takes this instructional tool a step further and provides detailed experiments on core networking topologies for use in this simulation environment. Various scenarios are presented within each topology: Review questions, a lab report, and exercises accompany each assignment as well. The manual also comes with directions for downloading the free easy-to-install software, the OPNET IT Guru Academic Edition. This software provides a virtual environment for modeling, analyzing, and predicting the performance of IT infrastructures, including applications, servers, and networking technologies.

Prepared by Professor Emad Aboelela of the University of Massachusetts Dartmouth, the experiments in the manual are closely tied to the organization of Computer Networks: A Systems Approach, 3e, and when used together are a complete tool for understanding how and why computer networks function as they do.

Features:

*Written by an instructor who has used OPNET simulation tools in his classroom for numerous demonstrations and real-world scenarios.
*Software download based on an award-winning product made by OPNET Technologies, Inc., whose software is used by thousands of commercial and government organizations worldwide, and by over 500 universities.
*Useful experimentation for professionals in the workplace who are interested in learning & demonstrating the capability of evaluating different commercial networking products, i.e., Cisco routers.
*Covers the core networking topologies and includes assignments on the ethernet, token rings, ATM, Switched LANs, Network Design, RIP, TCP, Queuing Disciplines, QoS, etc.

The First International Conference on Hybrid Learning was organized by City University of Hong Kong, Caritas Francis Hsu College and Caritas Bianchi College of Careers in August 2008. ICHL2008 was an innovative and consolidative experience for Hong Kong tertiary higher education. The conference aims to unify the traditional classroom face-to-face learning and Internet eLearning into one teaching and learning method––hybrid learning––for both teachers and students. Its audience are educators and eLearning practitioners. The conference obtained sponsorship from six local universities in Hong Kong: Hong Kong Baptist University, The Hong Kong Polytechnic University, The Hong Kong University of Science and Technology, University of Hong Kong, The Chinese University of Hong Kong, and Lingnan University. It was also sponsored by Pei Hua Education Foundation Limited, and K.C. Wong Education Foundation Limited.

Hybrid learning originated from North America in 2000 and is an ongoing trend. It is not merely a simple combination of direct teaching and eLearning, but comprises different learning strategies and important elements for teaching and learning. It focuses on student center learning and provides an environment for knowledge learning. Students are given more opportunities to be active learners and practice practical skills such as communication, collaboration, critical thinking, creativity, self-management, self-study, problem solving, analysis and numeracy.

It was our pleasure to have three keynote talks for the conference, namely, “You Can’t Do That in a Classroom! Realizing the Potential of Distributed Learning for On-Campus Students” by Cath Ellis, “A Proposal for a Lifecycle Process for Hybrid Learning Programs” by Won Kim, and “Just-in-Time Knowledge for Effective Hybrid Learning” by Michel Desmarais.

We are thankful for the effort of all the conference Organizing Committee members for organizing the conference, and also all the conference Program Committee members for reviewing the papers. Special thanks must go to Frances Yao for the support of City University of Hong Kong in holding the conference. The conference attracted about 142 submissions, and only 38 papers were accepted for the conference proceedings in the series Lecture Notes in Computer Science published by Springer.

On behalf of the conference Steering Committee members––Reggie Kwan from Caritas Francis Hsu College, Philips Fu Lee Wang from City University of Hong Kong, Victor Lee from The Chinese University of Hong Kong, and Joseph Fong from City University of Hong Kong––we trust you will enjoy the papers in this volume.

This guide to the contemporary toolbox of methods for data analysis will serve graduate students and researchers across the biological sciences. Modern computational tools, such as Maximum Likelihood, Monte Carlo and Bayesian methods, mean that data analysis no longer depends on elaborate assumptions designed to make analytical approaches tractable. These new 'computer-intensive' methods are currently not consistently available in statistical software packages and often require more detailed instructions. The purpose of this book therefore is to introduce some of the most common of these methods by providing a relatively simple description of the techniques. Examples of their application are provided throughout, using real data taken from a wide range of biological research. A series of software instructions for the statistical software package S-PLUS are provided along with problems and solutions for each chapter.

This graduate text introduces some of the most common computer-intensive methods, including Maximum Likelihood, Monte Carlo and Bayesian methods. Examples of their application using biological data are provided, along with a series of software instructions for the statistical software package S-PLUS and problems and solutions are included to aid understanding.
