Whether your background is security or networking, you can use this book to learn how to bridge the gap between a highly available, efficient network and one that strives to maximize security. The included secure network design techniques focus on making network and security technologies work together as a unified system rather than as isolated systems deployed in an ad-hoc way.Beginning where other security books leave off, Network Security Architectures shows you how the various technologies that make up a security system can be used together to improve your network’s security. The technologies and best practices you’ll find within are not restricted to a single vendor but broadly apply to virtually any network system. This book discusses the whys and hows of security, from threats and counter measures to how to set up your security policy to mesh with your network architecture. After learning detailed security best practices covering everything from Layer 2 security to e-commerce design, you’ll see how to apply the best practices to your network and learn to design your own security system to incorporate the requirements of your security policy. You’ll review detailed designs that deal with today’s threats through applying defense-in-depth techniques and work through case studies to find out how to modify the designs to address the unique considerations found in your network.Whether you are a network or security engineer, Network Security Architectures will become your primary reference for designing and building a secure network.This book is part of the Networking Technology Series from Cisco Press, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

For many IT organizations, today’s greatest challenge is to drive more value, efficiency, and utilization from data centers. Virtualization is the best way to meet this challenge. Data Center Virtualization Fundamentals brings together the comprehensive knowledge Cisco professionals need to apply virtualization throughout their data center environments. Leading data center expert Gustavo A. A. Santana thoroughly explores all components of an end-to-end data center virtualization solution, including networking, storage, servers, operating systems, application optimization, and security. Rather than focusing on a single product or technology, he explores product capabilities as interoperable design tools that can be combined and integrated with other solutions, including VMware vSphere. With the author’s guidance, you’ll learn how to define and implement highly-efficient architectures for new, expanded, or retrofit data center projects. By doing so, you can deliver agile application provisioning without purchasing unnecessary infrastructure, and establish a strong foundation for new cloud computing and IT-as-a-service initiatives. Throughout, Santana illuminates key theoretical concepts through realistic use cases, real-world designs, illustrative configuration examples, and verification outputs. Appendixes provide valuable reference information, including relevant Cisco data center products and CLI principles for IOS and NX-OS. With this approach, Data Center Virtualization Fundamentals will be an indispensable resource for anyone preparing for the CCNA Data Center, CCNP Data Center, or CCIE Data Center
certification exams.

The selection of air pollution control apparatus can be a daunting task even for experienced pollution control professionals. The Air Pollution Control Equipment Selection Guide eases the burden by providing extensive information on the best equipment available for any air pollution control problem. Instead of endorsing one technology over another, the author provides general information so that you can decide on the proper technology to use for any given application.The book offers ample introductory information including a helpful Air Pollution 101″ chapter that reviews the basics of air pollution control. The text is divided into sections that are organized by the primary technology employed, i.e., Quenching, Cooling, Particulate Removal, Gas Absorption, etc. This structure enables you to jump from section to section and quickly compare technologies. Each section defines the type of gas cleaning device, the basic physical forces used in it, its common sizes, and its most common uses.Many air pollution control problems are not solved with one type of device, but through using a variety of designs synergistically. To make this task easier, the author includes sections on each of these devices and notes where they are commonly used in concert with other equipment. Wherever possible, the text includes current photographs or drawings of typical equipment within that device type. Written in an easy to read style, Air Pollution Control Equipment Selection Guide serves as a technologically accurate reference that will facilitate the selection of air pollution control equipment for any operation.
