This is the only book available on building network DMZs, which are the cornerstone of any good enterprise security configuration. It covers market-leading products from Microsoft, Cisco, and Check Point. One of the most complicated areas of network technology is designing, planning, implementing, and constantly maintaining a demilitarized zone (DMZ) segment. This book is divided into four logical parts. First the reader will learn the concepts and major design principles of all DMZs. Next the reader will learn how to configure the actual hardware that makes up DMZs for both newly constructed and existing networks. Next, the reader will learn how to securely populate the DMZs with systems and services. The last part of the book deals with troubleshooting, maintaining, testing, and implementing security on the DMZ. The only book published on Network DMZs on the components of securing enterprise networks This is the only book available on building network DMZs, which are the cornerstone of any good enterprise security configuration. It covers market-leading products from Microsoft, Cisco, and Check Point Provides detailed examples for building Enterprise DMZs from the ground up and retro-fitting existing infrastructures

This book covers what an administrator needs to plan out and integrate a DMZ into a network for small, medium and Enterprise networks. In most enterprises the perception is that a firewall provides a hardened perimeter. However, the security of internal networks and hosts is usually very soft. In such an environment, a non-DMZ system that is offering services to the Internet creates the opportunity to leapfrog to other hosts in the soft interior of your network. In this scenario your internal network is fair game for any attacker who manages to penetrate your so-called hard perimeter.- There are currently no books written specifically on DMZs- This book will be unique in that it will be the only book that teaches readers how to build a DMZ using all of these products: ISA Server, Check Point NG, Cisco Routers, Sun Servers, and Nokia Security Appliances.- Dr. Thomas W. Shinder is the author of the best-selling book on Microsoft's ISA, Configuring ISA Server 2000. Customers of the first book will certainly buy this book.

Now that ActionScript is reengineered from top to bottom as a true object-oriented programming (OOP) language, reusable design patterns are an ideal way to solve common problems in Flash and Flex applications. If you're an experienced Flash or Flex developer ready to tackle sophisticated programming techniques with ActionScript 3.0, this hands-on introduction to design patterns is the book you need. ActionScript 3.0 Design Patterns takes you step by step through the process, first by explaining how design patterns provide a clear road map for structuring code that actually makes OOP languages easier to learn and use. You then learn about various types of design patterns and construct small abstract examples before trying your hand at building full-fledged working applications outlined in the book. Topics in ActionScript 3.0 Design Patterns include: Key features of ActionScript 3.0 and why it became an OOP language OOP characteristics, such as classes, abstraction, inheritance, and polymorphism The benefits of using design patterns Creational patterns, including Factory and Singleton patterns Structural patterns, including Decorator, Adapter, and Composite patterns Behavioral patterns, including Command, Observer, Strategy, and State patterns Multiple design patterns, including Model-View-Controller and Symmetric Proxy designs During the course of the book, you'll work with examples of increasing complexity, such as an e-business application with service options that users can select, an interface for selecting a class of products and individual products in each class, an action game application, a video record and playback application, and many more. Whether you're coming to Flash and Flex from Java or C++, or have experience with ActionScript 2.0, ActionScript 3.0 Design Patterns will have you constructing truly elegant solutions for your Flash and Flex applications in no time.

Discusses all types of corporate risks and practical means of defending against them. Security is currently identified as a critical area of Information Technology management by a majority of government, commercial, and industrial organizations. Offers an effective risk management program, which is the most critical function of an information security program.

Linux servers now account for 33% of all networks servers running worldwide (Source: IDC). The top 3 market share holders in the network server space (IBM, Hewlett-Packard, and Dell) all use Linux as their standard operating system. This book teaches Linux system administrators how to protect their servers from malicious threats.As with any technologies, increased usage results in increased attention from malicious hackers. For years a myth existed that Windows was inherently less secure than Linux, because there were significantly more attacks against Windows machines than Linux. This was a fallacy. There were more attacks against Windows machines because there were simply so many more Windows machines to attack. Now, the numbers tell the exact opposite story. Linux servers account for 1/3 of all servers worldwide, but in 2005 there were 3 times as many high-severity security vulnerabilities discovered on Linux servers (Source: IDC).This book covers Open Source security, implementing an intrusion detection system, unearthing Rootkits, defending against malware, creating Virtual Private Networks, and much more.The Perfect Reference for the Multitasked SysAdmin* Discover Why "Measure Twice, Cut Once" Applies to Securing Linux* Complete Coverage of Hardening the Operating System, Implementing an Intrusion Detection System, and Defending Databases* Short on Theory, History, and Technical Data that Is Not Helpful in Performing Your Job
