802. 1X Port-Based Authentication

Port-based authentication is a “network access control” concept in which a particular device is evaluated before being permitted to communicate with other devices located on the network. **802.1X Port-Based Authentication** examines how this concept can be applied and the effects of its application to the majority of computer networks in existence today. 802.1X is a standard that extends the Extensible Authentication Protocol (EAP) over a Local Area Network (LAN) through a process called Extensible Authentication Protocol Over LANs (EAPOL). The text presents an introductory overview of port-based authentication including a description of 802.1X port-based authentication, a history of the standard and the technical documents published, and details of the connections among the three network components. It focuses on the technical aspect of 802.1X and the related protocols and components involved in implementing it in a network. The book provides an in-depth discussion of technology, design, and implementation with a specific focus on Cisco devices. Including examples derived from the 802.1X implementation, it also addresses troubleshooting issues in a Cisco environment. Each chapter contains a subject overview. Incorporating theoretical and practical approaches, **802.1X Port-Based Authentication** seeks to define this complex concept in accessible terms. It explores various applications to today’s computer networks using this particular network protocol.

While information security is an ever-present challenge for all types of organizations today, most focus on providing security without addressing the necessities of staff, time, or budget in a practical manner.

Information Security Cost Management offers a pragmatic approach to implementing information security, taking budgetary and real-world constraints into consideration. By providing frameworks, step-by-step processes, and project management breakdowns, this book demonstrates how to design the best security strategy with the resources you have available.

Organized into five sections, the book-

• Focuses on setting the right road map so that you can be most effective in your information security implementations
  
• Discusses cost-effective staffing, the single biggest expense to the security organization
  
• Presents practical ways to build and manage the documentation that details strategy, provides resources for operating annual audits, and illustrates how to advertise accomplishments to senior management effectively
  
• Identifies high-risk areas, focusing limited resources on the most imminent and severe threats

I work for a network test equipment developer and have to test devices with multiple security types by multiple security device vendors. Most all enterprise security uses 802.1x whether wired or wireless. To many, 802.1x can be confusing at best, and mind-blowing at its worst. Edwin Brown's book is the best I read on the subject. It's a book that explains the concepts that are the building blocks of 802.1x in a conversation tone that neither talks over the heads of interested parties or simplify the subject to the point of being meaningless babble. Brown's style of writing comes across as sitting and listening to a very knowledge colleague help you to understand a subject. Brown's presents the information to you on an equal to equal basis so that you just "get it". The technical information is clear and thorough and serves as an excellent reference when you need to dig into a specific issue of 802.1x I'm pleased to have it on my bookshelf at work.
