With an ever increasing amount of information being transmitted electronically, it is important that security be considered in every phase of local area network design and maintenance. Although much emphasis has been placed on such things as wireless networks and remote access, it is imperative that the core local area network not be overlooked. Because the wired local area network is the nervous system of an organization’s Information Systems, great care must be taken to properly secure it. This chapter begins by looking at the implications for the wired local area network infrastructure security. Next, local area network segmentation and traffic isolation will be discussed. By using segmentation and isolation, there is the increased opportunity for security boundaries. Another concept that will be discussed is the security of the local area network equipment. The local area network is only functional if the core equipment is operational, so securing equipment is an important part of any security strategy. To conclude, restriction of local area network access will be investigated and an organizational approach will be discussed. Because more and more users need access to local area network resources, there must be a way to identify and restrict who is allowed on the network and what access they are granted. In wired local area network infrastructure security, organizations must remember they are only as secure as their weakest point. By carefully considering the various aspects of the local area network security during design, these weak points can be reduced and the overall security of the network increased. Although it is impossible to be 100% secure and still be functional, by using some general guidelines to secure the wired local area network, many threats to the network can be reduced if not eliminated.

This book has been written keeping in mind syllabi of all Indian universities and optimized the contents of the book accordingly. These students are the book's primary audience. Cryptographic concepts are explained using diagrams to illustrate component relationships and data flows. At every step aim is to examine the relationship between the security measures and the vulnerabilities they address. This will guide readers in safely applying cryptographic techniques. This book is also intended for people who know very little about cryptography but need to make technical decisions about cryptographic security. many people face this situation when they need to transmit business data safely over the Internet. This often includes people responsible for the data, like business analysts and managers. as well as those who must install and maintain the protections, like information systems administrators and managers. This book requires no prior knowledge of cryptography or related mathematics. Descriptions of low-level crypto mechanisms focus on presenting the concepts instead of the details. This book is intended as a reference book for professional cryptographers, presenting the techniques and algorithms of greatest interest of the current practitioner, along with the supporting motivation and background material. It also provides a comprehensive source from which to learn cryptography, serving both students and instructors. In addition, the rigorous treatment, breadth, and extensive bibliographic material should make it an important reference for research professionals. While composing this book my intention was not to introduce a collection of new techniques and protocols, but rather to selectively present techniques from those currently available in the public domain.
