This free networking PDF, 'Foundation,' Chapter 1 from the Computer Networks: A Systems Approach, Fifth Edition, will teach you what building materials you will need to construct a network from scratch. It explores the requirements that different applications and communities place on the network, introduces network architecture basics and options, discusses the networking and IT groups that should be consulted in network design, examines key elements in computer networks and identifies the key metrics used to evaluate the computer network performance. After reading the summary below, download the computer networking PDF of Chapter 1: 'Foundation,' from, Fifth Edition, by Larry L. Peterson and Bruce S. Davie (Morgan Kaufmann, 2012). Applications over your network A network must provide connectivity among a set of computers. While some networks limit the number of connected machines, others grow as large as a global wide area network ().

A home or small office may only require basic security while large businesses may require high-maintenance and advanced software and hardware to prevent malicious attacks from and. Types of attacks [ ] Networks are subject to from malicious sources. Attacks can be from two categories: 'Passive' when a network intruder intercepts data traveling through the network, and 'Active' in which an intruder initiates commands to disrupt the network's normal operation or to conduct reconnaissance and lateral movement to find and gain access to assets available via the network. Types of attacks include: • Passive • Network • • • • Encryption • Traffic analysis • Active: • Virus • Eavesdropping • Data modification. • A Role-Based Trusted Network Provides - interview with, senior VP of • Dave Dittrich, 2006-08-27 at the., University of Washington.

Techniques used by the attackers that attempt to compromise these decoy resources are studied during and after an attack to keep an eye on new techniques. Such analysis may be used to further tighten security of the actual network being protected by the honeypot.

Contents • • • • • • Network security concept [ ] Network security starts with, commonly with a username and a password. Since this requires just one detail authenticating the user name—i.e., the password—this is sometimes termed one-factor authentication. With, something the user 'has' is also used (e.g., a or ', an, or a ); and with three-factor authentication, something the user 'is' is also used (e.g., a or ). Once authenticated, a enforces access policies such as what services are allowed to be accessed by the network users. Though effective to prevent unauthorized access, this component may fail to check potentially harmful content such as or being transmitted over the network.

Networks do not remain fixed and must be able to evolve to accommodate technological changes, and networking and IT professionals must be able to manage them. Designing a network to meet those requirements isn't easy. The most basic requirements for a network are that they must provide general, cost-effective, fair and robust connectivity among a large number of computers. Network architecture as the blueprint Network architectures are general blueprints that guide the design and implementation of your network. The idea of abstraction, which hides your networking details behind a well-defined interface. The idea of abstraction is to make a model that can capture an important aspect of the system, but the challenge is to identify abstractions that simultaneously provide a service that proves useful in a large number of situations.

Network performance Naturally, computer networks are expected to perform well, and it's vital to understand the factors that can impact network performance. Network performance is measured by and.

Layering helps IT professionals build a network into more manageable components. Implementing network software One of the things that has made the Internet such a success is the fact that software running in general-purpose computers provides so much of its functionality, which means new functionality can be added easily. As a result, new applications and services can deployed in a heartbeat. Knowing how to deploy network software is an essential part of understanding computer networks. Specific instructions and visual representations for both the can be found in the networking PDF.

Abstractions naturally lead to layering. The idea is that you start with the services the underlying hardware offers, then add a sequence of layers, each of which provides a higher level of service.

A honeypot can also direct an attacker's attention away from legitimate servers. A honeypot encourages attackers to spend their time and energy on the decoy server while distracting their attention from the data on the real server. Similar to a honeypot, a honeynet is a network set up with intentional vulnerabilities. Its purpose is also to invite attacks so that the attacker's methods can be studied and that information can be used to increase network security. A honeynet typically contains one or more honeypots. Security management [ ] Security management for networks is different for all kinds of situations.

A network's bandwidth is the number of bits that can be transmitted over the network in a certain period of time. Latency is how long it takes a message to travel from one end of a network to the other and is measured in time. Equations found in this chapter can help you properly assess the performance of your computer or WAN network.

This computer networking PDF walks you through how to build a. Network requirements to accommodate application needs Efficiency is the key requirement of computer networks, which is why networks use packet switching as their main strategy. It's too simplistic to view a computer network as simply delivering packets among a collection of computers, however. A network should be thought of as the way to deliver a set of applications distributed over those computers.

• • • Network security consists of the and practices adopted to prevent and monitor access, misuse, modification, or denial of a and network-accessible resources. Network security involves the authorization of access to data in a network, which is controlled by the network administrator. Users choose or are assigned an ID and password or other authenticating information that allows them access to information and programs within their authority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Or an (IPS) help detect and inhibit the action of such. An may also monitor the network like wireshark and may be logged for audit purposes and for later high-level analysis. Newer systems combining unsupervised with full network traffic analysis can detect active network attackers from malicious insiders or targeted external attackers that have compromised a user machine or account. Communication between two hosts using a network may be encrypted to maintain privacy., essentially network-accessible resources, may be deployed in a network as surveillance and early-warning tools, as the honeypots are not normally accessed for legitimate purposes.

Network security is involved in organizations, enterprises, and other types of institutions. It does as its title explains: It secures the network, as well as protecting and overseeing operations being done. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.
