Download PDF CWNA® Certified Wireless Network Administrator Official Study Guide Third Edition by David D. Coleman

Sinopsis

If you have purchased this book or if you are thinking about purchasing this book, you probably have some interest in taking the CWNA® (Certified Wireless Network Administrator) certifi cation exam or in learning more about what the CWNA certification exam is about. We would like to congratulate you on this fi rst step, and we hope that our book can help you on your journey. Wireless networking is one of the hottest technologies on the market. As with many fast-growing technologies, the demand for knowledgeable people is often greater than the supply. The CWNA certifi cation is one way to prove that you have the knowledge and skills to support this growing industry. This Study Guide was written with that goal in mind.

This book was written to help teach you about wireless networking so that you have the knowledge needed not only to pass the CWNA certifi cation test, but also to be able to design, install, and support wireless networks. We have included review questions at the end of each chapter to help you test your knowledge and prepare for the test. We have also included labs, white papers, videos, and presentations on the book’s website (www.sybex.com/go/cwna3e) to further facilitate your learning.

Before we tell you about the certifi cation process and requirements, we must mention that this information may have changed by the time you are taking your test. We recommend that you visit www.cwnp.com as you prepare to study for your test to determine what the current objectives and requirements are.

If you have ever prepared to take a certifi cation test for a technology that you are unfamiliar with, you know that you are not only studying to learn a different technology, but probably also learning about an industry that you are unfamiliar with. Read on and we will tell you about CWNP.

CWNP is an abbreviation for Certifi ed Wireless Network Professional. There is no CWNP test. The CWNP program develops courseware and certifi cation exams for wireless LAN technologies in the computer networking industry. The CWNP certifi cation program is a vendor-neutral program.

The objective of CWNP is to certify people on wireless networking, not on a specifi c vendor’s product. Yes, at times the authors of this book and the creators of the certifi cation will talk about, demonstrate, or even teach how to use a specifi c product; however, the goal is the overall understanding of wireless, not the product itself. If you learned to drive a car, you had to physically sit and practice in one. When you think back and reminisce, you probably do not tell someone you learned to drive a Ford; you probably say you learned to drive using a Ford.

There are seven wireless certifi cations offered by the CWNP program: CWTS: Certified Wireless Technology Specialist CWTS is an entry-level enterprise WLAN certifi cation and a recommended prerequisite for the CWNA certifi cation. This certifi cation is geared specifi cally toward both WLAN sales and support staff for the enterprise WLAN industry. The CWTS certifi cation verifi es that sales and support staff are specialists in WLAN technology and have all the fundamental knowledge, tools, and terminology
to more effectively sell and support WLAN technologies.

CWNA: Certified Wireless Network Administrator The CWNA certifi cation is a foundation-level Wi-Fi certifi cation; however, it is not considered an entry-level technology certifi cation. Individuals taking this exam (exam PW0-105) typically have a solid grasp on network basics such as the OSI model, IP addressing, PC hardware, and network operating systems. Many candidates already hold other industry-recognized certifi cations, such as the CompTIA Network+ or Cisco CCNA, and are looking for the CWNA certifi cation to enhance or complement existing skills.

CWSP: Certified Wireless Security Professional The CWSP certifi cation exam (PW0-204) is focused on standards-based wireless security protocols, security policy, and secure wireless network design. This certifi cation introduces candidates to many of the technologies and techniques that intruders use to compromise wireless networks and that administrators use to protect wireless networks. With recent advances in wireless security, WLANs can be secured beyond their wired counterparts.

CWDP: Certified Wireless Design Professional The CWDP certifi cation exam (PW0-250) is a professional-level career certifi cation for networkers who are already CWNA certifi ed and have a thorough understanding of RF technologies and applications of 802.11 networks. This certification prepares WLAN professionals to properly design wireless LANs for different applications to perform optimally in different environments.

CWAP: Certified Wireless Analysis Professional The CWAP certifi cation exam (PW0-270) is a professional-level career certifi cation for networkers who are already CWNA certifi ed and have a thorough understanding of RF technologies and applications of 802.11 networks. This certification provides an in-depth look at 802.11 operations and prepares WLAN professionals to be able to perform, interpret, and understand wireless packet and spectrum analysis.

CWNE: Certified Wireless Network Expert The CWNE certifi cation is the highest-level certifi cation in the CWNP program. By successfully completing the CWNE requirements, you will have demonstrated that you have the most advanced skills available in today’s wireless LAN market. The CWNE certifi cation requires CWNA, CWAP, CWDP, and CWAP certifi cations. To earn the CWNE certifi cation, a rigorous application must be submitted and approved by CWNP’s review team.

Sinopsis

The content of this book is focused on the real world of wireless design. While this book provides all of the necessary information to pass the CWDP exam, the content is primarily focused on providing tangible value to immediately expand your wireless expertise. The knowledge you will obtain from this book will not only prove valuable if you plan on performing or participating in wireless designs, but will also help you understand what makes WLANs tick, spot design mistakes, troubleshoot pesky clients and applications, understand and quantify RF issues, and more.
 

Writing a book on wireless design in order to certify career professionals on designing for any equipment vendor isn ’ t a light undertaking. Vendors differ in their approach. There are even different architectures that greatly vary in the way they work, which is certainly the case between equipment vendors, but major architectural differences can even be found between product lines from a single equipment vendor.
 

The approach taken with the CWDP is far deeper in one area in particular than any other CWNP curriculum has ever embarked upon before — RF. Radio frequency fundamentals is an extremely tough area to teach and is probably the single least understood area of wireless networking across technical professionals. This book aims to change some of that. After all, a house can ’ t be built on a bad foundation. A wired network can ’ t be built using bad cabling. A supersonic jet . . . you get the point. Without the proper foundation for a wireless LAN, the performance will suffer and your network may ultimately fail.
 

The total focus of this book isn ’ t just the wireless network infrastructure we also explore the client devices that the wireless network infrastructure supports. In Wi - Fi, the communication link of a wireless client and an AP must be in parity with each other. For example, if you switch phones, even with the same mobile network carrier, your experience will vary. Where you may have once had good reception, you won ’ t now, and vice versa. It is no different with Wi - Fi. In fact, it is worse. Mobile network carriers have incredible control over the phones they will support and perform a great deal of engineering before placing them into the hands of customers. Wi - Fi, on the other hand, has many different equipment infrastructure vendors, an even greater disparity of operating modes, and a far greater variety of client devices with comparatively very little rigor and testing between them. Industry standards have a lot of wiggle room, and as a wireless network designer, you need to take this fact into account from the onset. After all, the very reason a wireless network exists is to support client devices.
 

If you have purchased this book or if you are thinking about purchasing this book, you probably have some interest in taking the CWDP ® (Certifi ed Wireless Design Professional) certifi cation exam or in learning more about what the CWDP certifi cation exam is about. We would like to congratulate you on this fi rst step, and we hope that our book can help you on your journey. Wireless networking is one of the hottest technologies available today and demands for mobility are great among a wide variety of industries. As with many fast - growing technologies, the demand for knowledgeable people is often greater than the supply. The CWDP certifi cation is your opportunity to distinguish yourself from others and a way to prove that you have the knowledge and skills to support this growing industry. This Study Guide was written with that goal in mind.
 

This book will teach you about wireless networking so that you have the knowledge needed not only to pass the CWDP certification test, but also to be able to design, install, and support wireless networks.

Download PDF THE HANDBOOK OF AD HOC WIRELESS NETWORKS by Mohammad Ilyas

Sinopsis

In recent years, the proliferation of mobile computing devices (e. g., laptops, handheld digital devices, personal digital assistants [P DAs], and wearable computers) has driven a revolutionary change in the computing world. As shown in Fig. 1.1, we are moving from the Personal Computer (PC) age (i.e., one computing device per person ) to the Ubiquitous Computing age in which individual users utilize, at the same time, several electroni c platforms through which they can access all the required information whenever and wherever they may be [47]. The nature of ubiquitous devices makes wireless networks the easiest solution for their inte rconnection. This has led to rapid growth in the use of wireless technologies for the Local Area Network (LAN) environment. Beyond supporting wireless connectivity for fixed, portable, and moving statio ns within a local area, wireless LAN (WLAN) technologies can provide a mobile and ubiquitous connection to Internet information services [10]. It is foreseeable that in the notso- distant future, WLAN technologies will be utilized largely as means to access the Internet. WLAN products consum e too much power and have excessive range for many personal consumer electronic and computer devices [40]. A new class of networks is therefore emerging: Personal Area Networks. A Personal Area N etwork (PAN) allows the proximal devices to dynamically share information with minimum power consumption [49].

LANs and PANs do not m eet all the networking requirements of ubiquitous computing. Situations exist where carrying and ho lding a computer are not practical (e.g., assembly line work). A wearable computer solves these prob lems by distributing computer components (e.g., head-mounted displays, microphones, earphones, processors, and mass storage) on the body [21,49]. Users can thus receive jobcritical information and mai ntain control of their devices while their hands remain free for other work. A network with a transmission range of a human body, i.e., a Body Area Network (BAN), constitutes the best solution for connecting wearable devices. Wireless connectivity is envisaged as a natural solution for BANs.

Download PDF Mastering Python Regular Expressions Leverage regular expressions in Python even for the most complex features by Félix López

Sinopsis

Regular expressions are text patterns that define the form a text string should have. Using them, among other usages, it will be possible to do the following activities:

• Check if an input honors a given pattern; for example, we can check whether a value entered in a HTML formulary is a valid e-mail address
• Look for a pattern appearance in a piece of text; for example, check if either the word "color" or the word "colour" appears in a document with just one scan
• Extract specific portions of a text; for example, extract the postal code of an address
• Replace portions of text; for example, change any appearance of "color" or "colour" with "red"
• Split a larger text into smaller pieces, for example, splitting a text by any appearance of the dot, comma, or newline characters

In this chapter, we are going to learn the basics of regular expressions from a language-agnostic point of view. At the end of the chapter, we will understand how regular expressions work, but we won't yet be able to execute a regular expression in Python. This is going to be covered in the next chapter. Because of this reason, the examples in this chapter will be approached from a theoretical point of view rather than being executed in Python.

Download PDF Network Analysis Using Wireshark Cookbook Over 80 recipes to analyze and troubleshoot network problems using Wireshark by Yoram Orzach

Sinopsis

In this chapter, we will cover the basic tasks related to Wireshark. In the Preface of this book, we discussed network troubleshooting and the various tools that can help us in the process. After reaching the conclusion that we need to use the Wireshark protocol analyzer, it's time to locate it for testing in the network, to configure it with basic configurations, and to adapt it to be user friendly.

While setting Wireshark for basic data capture is considered to be very simple and intuitive, there are many options that we can use in special cases; for example, when we capture data continuously over a connection and we want to split the capture file into small files, when we want to see names of the devices participating in the connection and not only IP addresses, and so on. In this chapter we will learn how to configure Wireshark for these special cases.

Another important issue is where to locate Wireshark to capture data. Will it be before a firewall or after it? On which side of the router should we connect it? On the LAN side or on the WAN side? What should we expect to receive in each one of them? All these issues and more will be covered in the Locating Wireshark recipe in this chapter, along with recommendations on how to do it.

Another important issue that will be covered in this chapter is how to configure time values, that is, how you would like Wireshark to present the arrival time of captured packets. This is significantly important when we capture data of time-sensitive applications, when it is important to see the timing of packets inside a TCP connection or a UDP flow. The next recipe will be on file manipulations, that is, how to save the captured data, whether we want to save the whole of it or part of it, save only filtered data, export that data into various formats, merge files (for example, when you want to merge captured files on two different router interfaces), and so on.

One more issue that will be discussed in this chapter is how to configure coloring rules. That is, how to configure Wireshark to present different packets and protocols in different colors. While Wireshark by default has its coloring scheme, we might want to configure it for special cases, for example, to give a special color to a specific protocol that we monitor or to a specific error or event that we expect. The Configuring coloring rules and navigation techniques recipe discusses these issues.

The last two recipes of the chapter will cover the configuration of the Wireshark preferences. These recipes discuss how to configure the user interface, that is, to configure the Wireshark windows, the columns and what to see in each one of them, text formats, and so on, along with specific protocol configurations; for example, which TCP ports should be resolved by default as a proxy service, whether or not to validate a protocol checksum, whether or not to calculate TCP timestamps, how to decode fields in the protocol header, and so on.

Download PDF Wireless Networks and Security Issues, Challenges and Research Trends by Shafiullah Khan

Sinopsis

Computer programs that radio amateurs use in their digital networks give various opportunities for checking user authentication before allowing access to sensitive parts of communication systems. Those systems include not only email servers that handle amateur radio messaging and file exchange, but also include radio-relay networks of digital repeaters that operate in big cities, or in rural and remote locations. This chapter summarizes results of experiments performed in real amateur packet radio networks as well as those provided by simulations with amateur radio software in local area networks. Our intention was to test security in accessing e-mail servers and radio relay systems within the average amateur radio digital infrastructure. This study suggests various methods which aim is to bridge the gap between the improved safety, and eventual discomfort in regular end-user’s and system administrator's activities. We focused our work to the following challenges: user authentication in amateur radio email servers; key management, i.e. obtaining, installing, and renewing secret documents (‘keys’) in between end-users and system administrators; encryption of email content and user passwords; attacks, epidemics, and appropriate countermeasures; and other protective actions that increase the security and satisfaction in average network participants. Described methods will help practitioners, students and teachers in computer science and communication technologies in implementing exciting amateur radio wireless opportunities within educational computer networks, as well as in planning new telecommunication systems.

Compared to security challenges we face to in our daily Internet-related activities, the amateur radio community does not suffer so much from exposures to known and unknown dangers that may come from their own wireless networks. For such positive situation we can thank to the global and local laws and regulations that require from all amateur radio candidates to pass written and oral, technical and regulatory tests, as well as to pass a basic security background check – before obtaining a license for transmitting radio signals. However, that does mean that the amateur radio digital infrastructure is completely secured and safe for every day’s use. Luckily, there are many opportunities in available safety measures, which support the integrity of both user's rights and system administrator's privileges. Personal computers that most of our schools, workplaces and homes are equipped with nowadays are capable to include security features in existing amateur radio programs or to become additionally enhanced with add-on software. Valuable information about available safety features can be easily obtained in regular amateur radio correspondence with peers, or by using dedicated information channels such as various ‘doc’ folders in email servers’ file repositories. For those who are likely to experiment in an isolated local area network (LAN), consisting of at least two or three machines, there are opportunities to replicate some of the experiments in this chapter.

As described in available sources on the amateur radio simulations [1], a simplest testing scenario might be in a LAN with at least two computers, which is a suitable situation for simulating radio traffic between two different amateur radio facilities, such as digital amateur radio-relay systems - commonly called digipeaters (a short of 'digital repeaters'), or BBS ('Bulletin Board Systems'; i.e., email servers). By simulating amateur radio traffic, we learn technologies and protocols used in real amateur radio frequency (RF) networks that include thousands radio-relay stations worldwide, as well as radio email servers and various home or work communicating solutions. For those of you who already have experience in dealing with ‘ham’ (=amateur radio) high frequency (HF), VHF or UHF communications, these homemade simulations will provide useful information on available solutions that are going to improve security of a wireless system that you might be responsible for.

One of the frequently asked questions during author’s amateur radio presentations at technical conferences and similar events – is how to ensure the safe access to the end-user email accounts – where the radio waves are the only media for transmitting information. In fact, due to the international regulations, the amateur radio traffic must travel as the open, no ciphered text, which means that all radio amateurs on a frequency are capable to ‘read’ everything that flows through the channel, by just simple activating his or her antenna, receiver, modem, and appropriate computer software [2]. The same rules also restrict what types of topics and discussions are acceptable in ham radio or not. For example, it is completely common to communicate the following themes: installation of antenna systems, power supply and grounding facilities; building amateur radio receivers and transmitters; programming amateur radio hardware and software; fixing small technical problems with computers and amateur radio stations, etc. That does not mean that general educational topics are not interesting for the local radio amateur community. Discussions about preparing technical conferences, papers and tutorials, or incoming technical expeditions and interesting school projects as well as non-classified details of scientific research or master and doctoral studies are completely suitable for distributing via amateur radio wireless networks. In opposite, it is not acceptable to discuss on things that include political, racial, national, social, sexual, business and similar potentially provocative themes. On the other side, there is a not a strict distinction between more or less priorities in the amateur radio communications. It is obvious that, according to the laws, emergency cases have priority, particularly when it comes to save human's lives or proprieties. But, in any occasion, one can be sure that amateur radio conversations are as 'private' as the talks in, say, public transportation systems, which actually means that there is not much 'privacy' there – if any. As mentioned, every user of a local amateur radio email server should be aware that unknown amateurs could easily read the text of his or her messages – either during an exchange of content with the email server, or during the exchange of content between those 'store & forward' systems, i.e. email servers. In such a relatively open environment, most countries have allowed the amateur radio communications primarily for an exchange of results of radio- and computer-related experiments that do not include commercial discussions, such as advertisements related to selling computers, other home appliances or any other goods. In the other words, the amateur radio laws support the major goal, which is to establish an ordinary '2-way' communication link between two or more wireless enthusiasts who might be the local school's students or teachers, as well as their parents, friends and other relatives. The basic idea is to increase the popularity of engineering and technology in young generations and to motivate them to continue education in technical professions such as electronics, electrical and mechanical engineering, computer science, hardware production, software development, etc. To summarize, when we come to commercial or other topics that are not appropriate for the amateur radio channels, it is the right time for all of us to switch from the amateur radio to commercial email service providers or similar public communicating systems.

Download PDF Systems Biology PROPERTIES OF RECONSTRUCTED NETWORKS by Bernhard Ø. Palsson

Sinopsis

Suddenly, systems biology is everywhere. What is it? How did it arise? The driving force for its growth is high-throughput (HT) technologies that allow us to enumerate biological components on a large scale. The delineation of the chemical interactions of these components gives rise to reconstructed biochemical reaction networks that underlie various cellular functions. Systems biology is thus not necessarily focused on the components themselves, but on the nature of the links that connect them and the functional states of the networks that result from the assembly of all such links. The stoichiometric matrix represents such links mathematically based on the underlying chemistry, and the properties of this matrix are key to determining the functional states of the biochemical reaction networks that it represents.

Download PDF THE 7STEP SUCCESS SYSTEM TO BUILDING A $1,000,000 NETWORK MARKETING DYNASTY by Joe Rubino

Sinopsis

Is network marketing, or multilevel marketing (MLM) as it was often referred to in years past, a legitimate vehicle that most anyone can use to create wealth from home? Or is it instead a black hole of frustration whereby the vast majority who pursue its seductive promises of economic and time freedom attempt to build wealth to various extents but never actually achieve the levels of success that they once dreamed of attaining? The reality of the situation is that it can be both! The fact that some are able to realize vast success, amass great wealth, and live the so-often-promised “life of choice” while many others struggle and eventually quit with little to show for their efforts, is not typically the result of luck or of chance.

To the contrary, there are many good reasons for the realization of either outcome. Network marketing, like other skilled professions, is both an art and a science. There are solid, predictable reasons why some people succeed in achieving the promises of wealth, the satisfaction of fun and fulfilling work, and the treasured time freedom that this industry can offer, while others put out a valiant effort, only to fail.

This book outlines a detailed 7-Step System to take the mystery out of why some are able to amass life-changing wealth and live the lifestyle of their fondest dreams. It is no wonder why such achievers would see this industry as a means to fun and freedom. The 7-Step System that follows is the result of 14 years of personal experience in building a multimillion dollar network. It is a compilation of the training of dozens of top network marketing leaders and thousands of hours of learning firsthand what works and what does not.

If you might be thinking that the training and coaching tips that follow are only effective for the elite, superbly gifted individuals, allow me to dispel this myth by sharing my story. I was first introduced to network marketing in 1991 when I answered a classified advertisement in a niche magazine. At the time, I was what most would consider a very successful dentist, earning a high six-figure yearly income. The problem I wrestled with was not the money. It was the stress, the physically demanding nature of the job (my neck and back problems were constant) and the responsibility of managing a team of 15 dental professionals. I didn’t just own my business; my business owned me. Time freedom was something only others enjoyed.

Download PDF THE HANDBOOK OF AD HOC WIRELESS NETWORKS by Mohammad Ilyas

Sinopsis

In recent years, the proliferation of mobile computing devices (e. g., laptops, handheld digital devices, personal digital assistants [P DAs], and wearable computers) has driven a revolutionary change in the computing world. As shown in Fig. 1.1, we are moving from the Personal Computer (PC) age (i.e., one computing device per person ) to the Ubiquitous Computing age in which individual users utilize, at the same time, several electroni c platforms through which they can access all the required information whenever and wherever they may be [47]. The nature of ubiquitous devices makes wireless networks the easiest solution for their inte rconnection. This has led to rapid growth in the use of wireless technologies for the Local Area Network (LAN) environment. Beyond supporting wireless connectivity for fixed, portable, and moving statio ns within a local area, wireless LAN (WLAN) technologies can provide a mobile and ubiquitous connection to Internet information services [10]. It is foreseeable that in the notso- distant future, WLAN technologies will be utilized largely as means to access the Internet.

WLAN products consum e too much power and have excessive range for many personal consumer electronic and computer devices [40]. A new class of networks is therefore emerging: Personal Area Networks. A Personal Area N etwork (PAN) allows the proximal devices to dynamically share information with minimum power consumption [49]. LANs and PANs do not m eet all the networking requirements of ubiquitous computing. Situations exist where carrying and ho lding a computer are not practical (e.g., assembly line work). A wearable computer solves these prob lems by distributing computer components (e.g., head-mounted displays, microphones, earphones, processors, and mass storage) on the body [21,49]. Users can thus receive jobcritical information and mai ntain control of their devices while their hands remain free for other work. A network with a transmission range of a human body, i.e., a Body Area Network (BAN), constitutes the best solution for connecting wearable devices. Wireless connectivity is envisaged as a natural solution for BANs.

Download PDF The Hacker’s Handbook The Strategy behind Breaking into and Defending Networks by Susan Young

Sinopsis

In many ways, this is almost the hardest chapter to pen in this book; in writing this, I am forced to relive the many occasions on which I have stood in a bookstore leafing through a technical book, trying to determine its value to the technical “excursion” I am currently embarked on. I generally start with the preface … (sigh). For this particular book, putting together an accurate, representative preface is a daunting task; The Hacker’s Handbook was deliberately constructed as a multifaceted text. Let me try — this book is about hacking, yes, but it is also weighted towards the security community. At the time when the authors started framing the book (May 2001), a significant number of books on the subject of digital hacking and security had already been published. In an effort to make some “space” for this book, we reviewed many of them and came to the conclusion that there was room for a book that adopted an analytical perspective on hacking and security and attempted to inform readers about the technical aspects of hacking that are, perhaps, least understood by system, network, and security administrators.

Sinopsis

Every aspect of industry—from power generation to automobile painting to food packaging—uses programmable controllers to expand and enhance production. In this book, you will learn about all aspects of these powerful and versatile tools. This chapter will introduce you to the basics of programmable controllers—from their operation to their vast range of applications. In it, we will give you an inside look at the design philosophy behind their creation, along with a brief history of their evolution. We will also compare programmable controllers to other types of controls to highlight the benefits and drawbacks of each, as well as pinpoint situations where PLCs work best. When you finish this chapter, you will understand the fundamentals of programmable controllers and be ready to explore the number systems associated with them.

Programmable logic controllers, also called programmable controllers or PLCs, are solid-state members of the computer family, using integrated circuits instead of electromechanical devices to implement control functions. They are capable of storing instructions, such as sequencing, timing, counting, arithmetic, data manipulation, and communication, to control industrial machines and processes. Figure 1-1 illustrates a conceptual diagram of a PLC application.

Download PDF Artificial Neural Networks for the Modelling and Fault Diagnosis of Technical Processes : Lecture Notes in Control and Information Sciences by Krzysztof Patan

Sinopsis

The diagnostics of industrial processes is a scientific discipline aimed at the detection of faults in industrial plants, their isolation, and finally their identification. Its main task is the diagnosis of process anomalies and faults in process components, sensors and actuators. Early diagnosis of faults that might occur in the supervised process renders it possible to perform important preventing actions. Moreover, it allows one to avoid heavy economic losses involved in stopped production, the replacement of elements and parts, etc.

Most of the methods in the fault diagnosis literature are based on linear methodology or exact models. Industrial processes are often difficult to model. They are complex and not exactly known, measurements are corrupted by noise and unreliable sensors. Therefore, a number of researchers have perceived artificial neural networks as an alternative way to represent knowledge about faults [1, 2, 3, 4, 5, 6, 7]. Neural networks can filter out noise and disturbances, they can provide stable, highly sensitive and economic diagnostics of faults without traditional types of models. Another desirable feature of neural networks is that no exact models are required to reach the decision stage [2]. In a typical operation, the process model may be only approximate and the critical measurements may be able to map internally the functional relationships that represent the process, filter out the noise, and handle correlations as well. Although there are many promising simulation examples of neural networks in fault diagnosis in the literature, real applications are still quite rare. There is a great necessity to conduct more detailed scientific investigations concerning the application of neural networks in real industrial plants, to achieve complete utilization of their attractive features.

One of the most frequently used schemes for fault diagnosis is the model based concept. The basic idea of model based fault diagnosis is to generate signals that reflect inconsistencies between nominal and faulty system operation conditions [8, 9, 10, 11]. Such signals, called residuals, are usually calculated by using analytical methods such as observers [9, 12], parameter estimation methods [13, 14] or parity equations [15, 16]. Unfortunately, the common drawback of these approaches is that an accurate mathematical model of the diagnosed plant

Download PDF Cryptography and Network Security Principles and Practices, Fourth Edition By William Stallings

Sinopsis

In this age of universal electronic connectivity, of viruses and hackers, of electronic eavesdropping and electronic fraud, there is indeed no time at which security does not matter. Two trends have come together to make the topic of this book of vital interest. First, the explosive growth in computer systems and their interconnections via networks has increased the dependence of both organizations and individuals on the information stored and communicated using these systems. This, in turn, has led to a heightened awareness of the need to protect data and resources from disclosure, to guarantee the authenticity of data and messages, and to protect systems from network-based attacks. Second, the disciplines of cryptography and network security have matured, leading to the development of practical, readily available applications to enforce network security.
