Computer Network Security

Protecting computer networks and their client computers against willful (or accidental) attacks is a growing concern for organizations and their information technology managers. This book draws upon the author s years of experience in computer security to describe a set of over 200 rules designed to enhance the security of a computer network (and its data) and to allow quick detection of an attack and development of effective defensive responses to attacks. Both novice and experienced network administrators will find this book an essential part of their professional tool kit. It is also essential reading for a corporate or organization manager who needs a solid understanding of the issues involved in computer security. Much literature is available on network and data security that describes security concepts, but offers so many different solutions to information security problems that it typically overwhelms both the novice and the experienced network administrator. This book presents a simple set of rules important in maintaining good information security. These rules or best practices are intended to be a recipe for setting up network and information security. This manual will take the mystery out of configuring an information security solution and provide a framework which the novice as well as experienced network administrator can follow and adapt to their network and data environment.

This volume provides a comprehensive look at computer networking from the point of view of the network administrator. It examines the key concepts the network administrator must possess to configure and manage today's complex computer networks. The volume guides readers from entry level computer networks to advanced concepts in Ethernet networks, router configuration, TCP/IP networks, local, campus and wide area network configuration, network security, optical networks, voice over IP and industrial networks. The volume provides an introduction to computer networks, computer fundamentals, interconnecting LANs, TCP/IP, introduction to routers, routing protocols, wide area networking, configuring and managing the campus network, network security, wireless networking, optical networks, voice over IP, the network server, Linux networking, and industrial networks. For entry level network administrator assistants, computer network supervisors, system administrators and LAN administrators.

Network security policy - A security policy is a generic document that outlines rules for computer network access, determines how policies are enforced and lays out some of the basic architecture of the company security environment. The document itself is usually several pages long and written by a committee.

Joint Functional Component Command for Network Warfare - The Joint Functional Component Command Network Warfare, JFCC-NW, is a the command responsible for coordinating offensive computer network operations for the United States Department of Defense. It is a subordinate command of United States Strategic CommandCommander, Joint Functional Component Command Network Warfare is dual-hatted as Director, National Security Agency]This component facilitates cooperative engagement with other national entities in computer network defense and offensive information warfare as part of the global information operations mission.

Witty (computer worm) - The Witty worm is a computer worm that attacks the firewall and other computer security products written by a particular company, Internet Security Systems (ISS). It was the first worm to take advantage of vulnerabilities in the very pieces of software designed to enhance network security, and carried a destructive payload, unlike previous worms.

Demilitarized zone (computing) - In computer security, a demilitarized zone (DMZ) or perimeter network is a network area (a subnetwork) that sits between an organization's internal network and an external network, usually the Internet. The point of a DMZ is that connections from the internal and the external network to the DMZ are permitted, whereas connections from the DMZ are only permitted to the external network -- hosts in the DMZ may not connect to the internal network.

Computer Network Security System - Computer Network Security System Security protocol notation - Security (engineering) protocol notation is a way of expressing a protocol of correspondence between entities of a dynamic system, such as a computer network. It allows reasoning about the properties of such a system, and provides a formal model, to which the BAN logic can be applied. Network computer - A network computer is a lightweight computer system that operates exclusively via a network connection. As such, it does not have secondary storage such as ...

Computer Networking Security - Computer Networking Security Dancing pigs (computer security) - In computer security, dancing pigs or the dancing pigs problem refers to a statement on user attitudes to computer security: that users primarily desire features without considering security, and so security must be designed in without the computer having to ask a technically ignorant user quote is commonly attributed to either Edward Felten] or [[Bruce Schneier. Felten said in Securing Java (1999), chapter one, part seven a choice between dancing pigs and security, users ...
