Network Security Assessment: Know Your Network
by Chris McnabHow secure is your network? The best way to find out is to attack it. Network Security Assessment provides you with the tricks and tools professional security consultants use to identify and assess risks in Internet-based networks-the same penetration testing model they use to secure government, military, and commercial networks. With this book, you can adopt, refine, and reuse this testing model to design and deploy networks that are hardened and immune from attack.Network Security Assessment demonstrates how a determined attacker scours Internet-based networks in search of vulnerable components, from the network to the application level. This new edition is up-to-date on the latest hacking techniques, but rather than focus on individual issues, it looks at the bigger picture by grouping and analyzing threats at a high-level. By grouping threats in this way, you learn to create defensive strategies against entire attack categories, providing protection now and into the future.Network Security Assessment helps you assess:Web services, including Microsoft IIS, Apache, Tomcat, and subsystems such as OpenSSL, Microsoft FrontPage, and Outlook Web Access (OWA)Web application technologies, including ASP, JSP, PHP, middleware, and backend databases such as MySQL, Oracle, and Microsoft SQL ServerMicrosoft Windows networking components, including RPC, NetBIOS, and CIFS servicesSMTP, POP3, and IMAP email servicesIP services that provide secure inbound network access, including IPsec, Microsoft PPTP, and SSL VPNsUnix RPC services on Linux, Solaris, IRIX, and other platformsVarious types of application-level vulnerabilities that hacker tools and scripts exploitAssessment is the first step any organization should take to start managing information risks correctly. With techniques to identify and assess risks in line with CESG CHECK and NSA IAM government standards, Network Security Assessment gives you a precise method to do just that.

ActionScript 3.0 Programming: Overview, Getting Started, and Examples of New Concepts
by William SandersActionScript 3.0 Programming: Overview, Getting Started, and Examples of New Concepts is a 76-page document designed to introduce those familiar with general programming principles to ActionScript 3.0. ActionScript 3.0 compiles and runs much faster than preceding versions, and the reasons have much to do with the structural changes Adobe has added: You truly do need to use ActionScript differently than you have previously, if you're already ActionScript programmer. If you're new to ActionScript, but are looking at it from a Java or C++ or C# perspective, you may be intrigued at how different ActionScript is now compared with what you'd known it or heard it to be before.This document employs reusable code examples to demonstrate the basic functionality of ActionScript 3.0 in the following topic areas: Packages and Classes; Display Programming; Movie Clips and Buttons; and Basic Structures. A concluding section helps those unfamiliar with OOP (Object Oriented Programming) and Design Patterns get acquainted with these concepts, as a knowledge of them will greatly benefit anyone getting into ActionScript 3.0 who wants to get the most out of it.

Responsive & Fast: Implementing High-Performance Responsive Design
by Guy PodjarnyIs Responsive Web Design (RWD) slowing your site down? It doesn’t have to. With this concise book, you’ll learn practical techniques for improving performance with RWD, including a default set of guidelines you can use as an easy starting point. Web performance researcher and evangelist Guy Podjarny walks you through several existing solutions for dealing with RWD performance problems, and offers advice for choosing optimizations that will be most useful for your needs.RWD performance problems stem from excessive downloads of resources, including images, JavaScript and CSS, and HTML—downloads designed to let your web application adapt to different screen sizes. Podjarny presents a series of increasingly larger-scope solutions to each issue, including client-side techniques and RESS (Responsive + Server Side Components).Address performance issues by starting with Podjarny’s default guidelinesUse a JavaScript image loader and an image transcoding service to create Responsive ImagesReduce JavaScript and CSS downloads with asynchronous scripts, conditional loading, and multi-viewport CSSPrioritize resources to avoid excess content in RWD and defer the load of any content that’s not criticalExplore server-side Adaptive Delivery and RESS solutions as an alternative to “pure” RWDGuy Podjarny, or Guypo for short, is the Chief Technology Officer (CTO) of Akamai’s Web Experience business unit.
