The Network Defense Series from EC-Council | Press comprises of 5 books designed to educate learners from a vendor-neutral standpoint on how to defend the networks they manage. This series covers the fundamental skills in evaluating the internal and external threats to the network security and design, how to enforce the network level security policies, and how to ultimately protect an organization's information. The books in the series cover a broad range of topics from the secure network fundamentals, protocols & analysis, standards and policy, hardening infrastructure, configuring IPS, IDS, firewalls, bastion host, and honeypots. Learners completing this series will have a full understanding of the defensive measures taken to secure their organization's information and along with the proper experience; these books will prepare readers for the EC-Council Network Security Administrator (E|NSA) certification.

A thorough understanding of the network technologies and security fundamentals is required before designing any defensive measure to protect an organization's information. This book, the first in the series, is designed to provide the foundational knowledge to the potential security administrator from a vendor-neutral perspective covering everything from standard secure network topology, network media and transmission, classifications, and a complete view of the network security equipment.

This book discusses the operations of various key elements in a network, IP address assignments, Domain Name Spaces, working and functional categories of gateways, media types used to connect networks, media access methods, OSI and TCP/IP reference models, data transmission methods, logical network arrangements, network classes, physical arrangements of the network (including topologies), and network equipment functions.

1.Fundamentals of Network
Chapter Brief:
A network is a group of computers connected together that allows information to be exchanged between the computers. It can be divided in several subnets depending on the usage and the requirements.
2.Network protocols
Chapter Brief:
Network protocols are rules and conventions for communication between network devices. Protocols for computer networking all generally use packet switching techniques to send and receive messages in the form of packets. A network protocol facilitates device identification and data transfer.
3.Protocol Analysis
Chapter Brief:
4.IEEE Standards
ChapterBrief:
The Institute of Electrical and Electronics Engineers (IEEE) is a non-profit organization. It is one of the leading professional associations for the advancement of technology.
5.Security Standard Organizations
Chapter Brief:
Security standards enable organizations to practice security techniques to minimize the number of the successful security attacks.
6.Security Standards
Chapter Brief:
The security standards support the businesses that take advantage of working with computers and electronic commerce on the Internet. Although there are more data security products and security services available today, the rapid growth in Internet technology also creates new opportunities for hackers and businesses.
This chapter describes the Introduction to Internet Standards, Standards Creation Committee, and request for Comment Evolution, and Unshielded Twisted Pair (UTP) Categories. This chapter also discusses on how to obtain RFCs via File Transfer Protocol (FTP) and lists various cabling standards.
