The book provides the reader with a one-stop highway to learning about the fundamentals of computer networking, Internet connectivity, cybersecurity, and hacking.
If we are to believe in Moore’s law, then every passing day brings new and advanced changes to the technology arena. We are as amazed by miniaturization of computing devices as we are amused by their speed of computation. Everything seems to be in ? ux and moving fast. We are also fast moving towards ubiquitous computing. To achieve this kind of computing landscape, new ease and seamless computing user interfaces have to be developed. Believe me, if you mature and have ever program any digital device, you are, like me, looking forward to this brave new computing landscape with anticipation. However, if history is any guide to use, we in information security, and indeed every computing device user young and old, must brace themselves for a future full of problems. As we enter into this world of fast, small and concealable ubiquitous computing devices, we are entering fertile territory for dubious, mischievous, and malicious people. We need to be on guard because, as expected, help will be slow coming because ? rst, well trained and experienced personnel will still be dif? cult to get and those that will be found will likely be very expensive as the case is today.
The world of IT is always evolving, but in every area there are stable, core concepts that anyone just setting out needed to know last year, needs to know this year, and will still need to know next year. The purpose of the Foundations series is to identify these concepts and present them in a way that gives you the strongest possible starting point, no matter what your endeavor. Network Security Foundations provides essential knowledge about the principles and techniques used to protect computers and networks from hackers, viruses, and other threats. What you learn here will benefit you in the short term, as you acquire and practice your skills, and in the long term, as you use them. Topics covered include: Why and how hackers do what they do How encryption and authentication work How firewalls work Understanding Virtual Private Networks (VPNs) Risks posed by remote access Setting up protection against viruses, worms, and spyware Securing Windows computers Securing UNIX and Linux computers Securing Web and email servers Detecting attempts by hackers

It introduces the concepts, techniques, methods, approaches, and trends needed by security specialists to improve their security skills and capabilities. Further, it provides a glimpse into future directions where security techniques, policies, applications, and theories are headed. The book represents a collection of carefully selected and reviewed chapters written by diverse security experts in the listed fields and edited by prominent security researchers. Complementary slides are available for download on the book’s website at Springer.com.
A hands-on, do-it-yourself guide to securing and auditing a network CNN is reporting that a vicious new virus is wreaking havoc on the world’s computer networks. Somebody’s hacked one of your favorite Web sites and stolen thousands of credit card numbers. The FBI just released a new report on computer crime that’s got you shaking in your boots. The experts will tell you that keeping your network safe from the cyber-wolves howling after your assets is complicated, expensive, and best left to them. But the truth is, anybody with a working knowledge of networks and computers can do just about everything necessary to defend their network against most security threats. Network Security For Dummies arms you with quick, easy, low-cost solutions to all your network security concerns. Whether your network consists of one computer with a high-speed Internet connection or hundreds of workstations distributed across dozens of locations, you’ll find what you need to confidently: Identify your network’s security weaknesses Install an intrusion detection system Use simple, economical techniques to secure your data Defend against viruses Keep hackers at bay Plug security holes in individual applications Build a secure network from scratch Leading national expert Chey Cobb fills you in on the basics of data security, and he explains more complex options you can use to keep your network safe as your grow your business. Among other things, you’ll explore: Developing risk assessments and security plans Choosing controls without breaking the bank Anti-virus software, firewalls, intrusion detection systems and access controls Addressing Unix, Windows and Mac security issues Patching holes in email, databases, Windows Media Player, NetMeeting, AOL Instant Messenger, and other individual applications Securing a wireless network E-Commerce security Incident response and disaster recovery Whether you run a storefront tax preparing business or you’re the network administrator at a multinational accounting giant, your computer assets are your business. Let Network Security For Dummies provide you with proven strategies and techniques for keeping your precious assets safe.
Traditional intrusion detection and logfile analysis are no longer enough to protect today’s complex networks. In this practical guide, security researcher Michael Collins shows you several techniques and tools for collecting and analyzing network traffic datasets. You’ll understand how your network is used, and what actions are necessary to protect and improve it. Divided into three sections, this book examines the process of collecting and organizing data, various tools for analysis, and several different analytic scenarios and techniques. It’s ideal for network administrators and operational security analysts familiar with scripting. Explore network, host, and service sensors for capturing security data Store data traffic with relational databases, graph databases, Redis, and Hadoop Use SiLK, the R language, and other tools for analysis and visualization Detect unusual phenomena through Exploratory Data Analysis (EDA) Identify significant structures in networks with graph analysis Determine the traffic that’s crossing service ports in a network Examine traffic volume and behavior to spot DDoS and database raids Get a step-by-step process for network mapping and inventory
Guides Students in Understanding the Interactions between Computing/Networking Technologies and Security Issues Taking an interactive, "learn-by-doing" approach to teaching, Introduction to Computer and Network Security: Navigating Shades of Gray gives you a clear course to teach the technical issues related to security. Unlike most computer security books, which concentrate on software design and implementation, cryptographic tools, or networking issues, this text also explores how the interactions between hardware, software, and users affect system security. The book presents basic principles and concepts, along with examples of current threats to illustrate how the principles can either enable or neutralize exploits. Students see the importance of these concepts in existing and future technologies. In a challenging yet enjoyable way, they learn about a variety of technical topics, including current security exploits, technical factors that enable attacks, and economic and social factors that determine the security of future systems. Extensively classroom-tested, the material is structured around a set of challenging projects. Through staging exploits and choosing countermeasures to neutralize the attacks in the projects, students learn: How computer systems and networks operate How to reverse-engineer processes How to use systems in ways that were never foreseen (or supported) by the original developers Combining hands-on work with technical overviews, this text helps you integrate security analysis into your technical computing curriculum. It will educate your students on security issues, such as side-channel attacks, and deepen their understanding of how computers and networks work.
