Over the last couple years NAC has moved from being a niche solution and is becoming a mainstream requirement for enterprise organizations. This creates a new set of skills for the network engineer to master. Unfortunately there have been few resources for self study, until now. This book provides everything you need to get started with NAC, whether you are just evaluating the technology or rolling out a full deployment. Get this book and you will have the skills foundation that are sure to be a requirement of any network engineer in the very near future. You will find this to be a very useful book if you are interested in developing a cohesive and viable NAC policy and creating sound and effective NAC enforcement. NAC is a hot buzz-word right now and very few companies have a real handle on how to make use it. This book goes a long way toward separating fact from fiction and making NAC an effective piece of network security. This is a comprehensive book and covers ROI, design options, best practices, configuration examples, troubleshooting. Whether you are evaluating, implementing, or deploying there is something for everyone. Highly recommended. Pick up a copy and get up to speed on this fast growing technology.
Network access control (NAC) is how you manage network security when your employees, partners, and guests need to access your network using laptops and mobile devices. Network Access Control For Dummies is where you learn how NAC works, how to implement a program, and how to take real-world challenges in stride. You’ll learn how to deploy and maintain NAC in your environment, identify and apply NAC standards, and extend NAC for greater network security. Along the way you’ll become familiar with what NAC is (and what it isn’t) as well as the key business drivers for deploying NAC. Learn the steps of assessing, evaluating, remediating, enforcing, and monitoring your program Understand the essential functions of Authentication, Authorization, and Accounting Decide on the best NAC approach for your organization and which NAC policies are appropriate Discover how to set policies that are enforceable and reasonable enough to be followed, yet still effective Become familiar with the architectures and standards essential to NAC Involve and motivate everyone in the organization whose support is critical to a successful implementation Network Access Control For Dummies shows you the steps for planning your implementation, who should be involved, where enforcement should occur, and much more. When you flip the switch, you’ll know what to expect.

Cisco NAC Appliance Enforcing Host Security with Clean Access Authenticate, inspect, remediate, and authorize end-point devices using Cisco NAC Appliance Jamey Heary, CCIE® No. 7680 Contributing authors: Jerry Lin, CCIE No. 6469, Chad Sullivan, CCIE No. 6493, and Alok Agrawal With today's security challenges and threats growing more sophisticated, perimeter defense alone is no longer sufficient. Few organizations are closed entities with well-defined security perimeters, which has led to the creation of perimeterless networks with ubiquitous access. Organizations need to have internal security systems that are more comprehensive, pervasive, and tightly integrated than in the past. Cisco® Network Admission Control (NAC) Appliance, formerly known as Cisco Clean Access, provides a powerful host security policy inspection, enforcement, and remediation solution that is designed to meet these new challenges. Cisco NAC Appliance allows you to enforce host security policies on all hosts (managed and unmanaged) as they enter the interior of the network, regardless of their access method, ownership, device type, application set, or operating system. Cisco NAC Appliance provides proactive protection at the network entry point. Cisco NAC Appliance provides you with all the information needed to understand, design, configure, deploy, and troubleshoot the Cisco NAC Appliance solution. You will learn about all aspects of the NAC Appliance solution including configuration and best practices for design, implementation, troubleshooting, and creating a host security policy. Jamey Heary, CCIE® No. 7680, is a security consulting systems engineer at Cisco, where he works with its largest customers in the northwest United States. Jamey joined Cisco in 2000 and currently leads its Western Security Asset team and is a field advisor for its U.S. Security Virtual team.

Cisco Network Admission Control Volume I: NAC Framework Architecture and Design A guide to endpoint compliance enforcement Today, a variety of security challenges affect all businesses regardless of size and location. Companies face ongoing challenges with the fight against malware such as worms, viruses, and spyware. Today’s mobile workforce attach numerous devices to the corporate network that are harder to control from a security policy perspective. These host devices are often lacking antivirus updates and operating system patches, thus exposing the entire network to infection. As a result, worms and viruses continue to disrupt business, causing downtime and continual patching. Noncompliant servers and desktops are far too common and are difficult to detect and contain. Locating and isolating infected computers is time consuming and resource intensive. Network Admission Control (NAC) uses the network infrastructure to enforce security policy compliance on all devices seeking to access network computing resources, thereby limiting damage from emerging security threats. NAC allows network access only to compliant and trusted endpoint devices (PCs, servers, and PDAs, for example) and can restrict the access of and even remediate noncompliant devices. Cisco Network Admission Control, Volume I, describes the NAC architecture and provides an in-depth technical description for each of the solution components. This book also provides design guidelines for enforcing network admission policies and describes how to handle NAC agentless hosts. As a technical primer, this book introduces you to the NAC Framework solution components and addresses the architecture behind NAC and the protocols that it follows so you can gain a complete understanding of its operation. Sample worksheets help you gather and organize requirements for designing a NAC solution. Denise Helfrich is a technical program sales engineer that develops and supports global online labs for the World Wide Sales Force Development at Cisco®. Lou Ronnau, CCIE® No. 1536, is a technical leader in the Applied Intelligence group of the Customer Assurance Security Practice at Cisco. Jason Frazier is a technical leader in the Technology Systems Engineering group for Cisco. Paul Forbes is a technical marketing engineer in the Office of the CTO, within the Security Technology Group at Cisco. Understand how the various NAC components work together to defend your network Learn how NAC operates and identifies the types of information the NAC solution uses to make its admission decisions Examine how Cisco Trust Agent and NAC-enabled applications interoperate Evaluate the process by which a policy server determines and enforces a policy Understand how NAC works when implemented using NAC-L2-802.1X, NAC-L3-IP, and NAC-L2-IP Prepare, plan, design, implement, operate, and optimize a network admission control solution This security book is part of the Cisco Press® Networking Technology Series.
