Norton Internet Security 2009 Review

Norton Internet Security 2009
Average Reviews:

(More customer reviews)
After years of running Norton Antivirus products, with ever increasing demands on system resources, as well as slowing down the machines these products were installed on, the completely rewritten version of Norton Internet Security 2009 has gone a very long way towards correcting years of bloatware code that was made worse with every new release.
This version installs fast, runs fast, and is almost entirely unobtrusive, with one very major exception.
This software will break your home or small business network.
In a well-documented bug first discovered in October 2008, Norton interferes with, and eventually blocks access to other machines on your home network. Norton admits there is a problem, and has been stalling customers for months with promises for a fix, yet keeps pushing the release date out further and further.
Install Norton 2009, and eventually all of the computers on your home network under My Network Places will disappear, and will eventually be blocked from access. While you can frequently manually reach your other networked machines by typing their addresses directly into an address bar, software that depends on access to your other networked machines directly (index, backup, small business collaboration tools, etc.) usually cannot work this way, and you are effectively cut off from using those applications. Worse, over time, Norton will begin periodically cutting off access to your networked machines. Suddenly file copying between machines fails, extremely long delays in accessing other computers on your network occurs, and your frustration level mounts.
Norton admits the only current solution to this problem is to completely uninstall Norton 2009 Antivirus/Internet Security products. There is no other workaround.
Worse yet, the responsiveness of the company to major software bugs has been less than acceptable. It literally takes months for even the most urgent bugs to get identified, corrected, and then put through a laborious test procedure. To add insult to injury, it then takes up to six additional weeks for the fixed code to be incorporated into their slow update release schedule and finally reach every customer.
This truly mars an otherwise promising product and makes it an unacceptable option for those dependent on networked machines, such as a home or small business network. If you are dependent on your network to access remote hard drives or collaborate in an office environment, Norton 2009 products are absolutely not acceptable for use and I strongly recommend you look elsewhere until the company finally fixes the problem.
A very lengthy discussion about this problem can be found on the Norton Community Forum. Simply search for "NAV blocks access to hard disk." The later discussions in the thread contain the most pertinent information.

The World Is Open: How Web Technology Is Revolutionizing Education Review

The World Is Open: How Web Technology Is Revolutionizing Education
Average Reviews:

(More customer reviews)
I've seen educators struggle to herd their faculty cats, hire staff under industrial-era rules, and strive to accommodate students that know more than their professors about anything outside the "teach to test" topic. This is one of three books that I have digested these past ten days, along with Making Learning Whole: How Seven Principles of Teaching Can Transform Education and (in galley form) Reflexive Practice: Professional Thinking for a Turbulent World. All three are 6 STAR books, and since I have only given this grade to 99 books out of the 1636, so at 6% of the total, this is saying a lot IMHO. These three books together, along with Don't Bother Me Mom--I'm Learning!, The Emerging Worldwide Electronic University: Information Age Global Higher Education (Praeger Studi) and my favorite deep books, Philosophy and the Social Problem: The Annotated Edition and Consilience: The Unity of Knowledge, comprise a basic library for anyone wishing to develop global strategies for taking any university into the future. Of course there are other great books, but in my limited experience, these are a foundation.
DO NOT READ THIS BOOK without first looking at the web site WorldIsOpen.com, and more specifically, the only part of the website that I found to be essential, the sixteen pages of links to every online resource mentioned in the book. Had I done this first, I could have cut my note-taking time in half. As it is, I have created a sixteen page alphabetized list of all the references, and include that in my more robust review of this book at Phi Beta Iota, the Public Intelligence Blog, where I can do things (such as link to my other 80+ education book reviews and include non-Amazon links) that Amazon simply will not allow.
BUY THIS BOOK. It is in my view an essential foundation for any university as well as any lower school or continuing education and training program that desires to increase its effectiveness by a thousand fold while also increasing its global reach by a million fold.
The basic premise up front: anyone can learn anything from anyone at anytime. The author charms me early on with his recognition of how broken our existing educational delivery system is, and his passion for how information and communication technologies (ICT) can empower all (at the end of the book he specifically focuses on the five billion poor and how they can learn via mobile learning) and create an "egalitarian learning frenzy." He considers education to be a human right--I agree and would add that it is also the only way we will achieve Nonzero: The Logic of Human Destiny by harnessing Collective Intelligence: Creating a Prosperous World at Peace.
In his critique of existing education the author excels at pointing out all that is not included in the narrow educational curriculums constrained by cultural bias and the physics of a 24-hour day, budgets, and so on. In his view textbooks and classrooms are on the way down, and oral and visual digital and especially mobile learning is on the way up.
I am immediately--and then continuously--impressed by the very deep and broad homework the author has done, integrating into every chapter so many actual resources (all with links at the book's website, soon books like this will come with embedded QR Code to make the analog to digital connection simple). The book is a tour of the horizon and a triumph of logic and presentation.
The ten key trends for those who read this review at Phi Beta Iota are:
01 Web-Searching
02 Blended Learning
03 Free/Open Source Software (F/OSS)
04 OpenCourseWare
05 Learning Portals
06 Learners as Teachers
07 Electronic Collaboration
08 Alternative Reality including Serious Games
09 Mobile Real-Time Learning
10 Networks of Personalized Learning
As my oldest son prepares to attend the Rochester Institute of Technology (RIT), the only school he was willing to apply to because of its new media program, I am totally pumped by the author's emphasis on education rather than any of the more obvious global threats (see A More Secure World: Our Shared Responsibility--Report of the Secretary-General's High-level Panel on Threats, Challenges and Change, and on his emphasis on how visualization and new media will be the lever that will move education. Poverty is the number one high-level threat to humanity, and later on in the book my esteem for Nicholas Negroponte goes up as I digest a quote that connects low-cost laptops to education to the eradication to poverty to creating a prosperous world at peace. These guys get it, and virtually all our legislative and executive "leaders," at both the state and national levels, do not get it because they are not being "incentivized" to get it.
The author has a gift for summative categorization and draws ably and with full attribution on many other minds throughout this book. I like:
Globalization 1.0: Nations
Globalization 2.0: Multinational Corporations (MNC)
Globalization 3.0: Singular Individuals
Globalization 4.0: "We"
He points out that online learning favors collaborative work and team learning; problem-based learning (rather than applying canned "solutions"); generative (incremental modification); exploratory; and interactive learning. In short, rote learning in the classroom is constraining while online learning is liberating and empowering.
Most of my notes are obviated by the author's superb resource section (WorldIsOpen.com/resources.php). Here are the highlights outside of my listing all of the leads I want to follow up, related to the section of the book.
01 Web-Searching. Faster is not better, still missing a great deal of structure and substance on the Internet. Open everything is here to stay--open content, open office, open library, open document. See my briefing on "Open Everything" at oss.net/GNOME.
02 Blended Learning. We must stop holding students back! Online pushes reading and writing skills as well as presentation skills and technology skills. We must rapidly accelerate means of recognizing learning accomplished online (e.g. challenge tests). Learning must be offered "on demand" and across every device imaginable (the MP3 player shines in this book). However, blended means just that--online is not a substitute for face to face and team interaction.
03 Free/Open Source Software (F/OSS). I am the primary proponent for Open Source Intelligence (OSINT) and now public intelligence, and as an honorary hacker have long understood and admired the F/OSS movement started by Richard Stallman. Along with OSINT and F/OSS, Open Spectrum completes the Tri-Fecta. It is essential, if we are to rapidly achieve all we are capable of, that we leverage F/OSS across all university functionalities. This is also how we enable the eight tribes of intelligence (academia, civil society, commercial, government, law enforcement, media, military, and non-governmental) to do multinational, multiagency, multidisciplinary, multidomain information-sharing and sense-making (M4IS2, a Swedish military concept I have adopted).
04 OpenCourseWare. MIT, which is also the birthplace of modern hacking as recounted in The Second Self: Computers and the Human Spirit, Twentieth Anniversary Edition, gets full credit all it has done in this area, and the author provides a very rich discussion of many other similar initiatives including the Peer to Peer University (P2PU).
05 Learning Portals. These are in their infancy. The author cites a number of important ones, and the availability of platforms to create more learning portals, but he does not address the abject fragmentation of knowledge and the urgency of creating an overall architecture so that we can restore the links between disciplines and domains and do "Whole Learning."
06 Learners as Teachers. Here again the author is phenomenal at reviewing some of the most important initiatives in this area, and my notes are irrelevant in the face of his superb listing of electronic links, chapter by chapter, at his WorldIsOpen.com. He does observe that quality control and sufficiency of funding are issues, and I certainly agree, with the observation that there is plenty of money for education, we just have to eliminate corruption in government....
07 Electronic Collaboration. This is a section I want to come back to, after I have checked out 1kg, TwinBooks, ePals, iLearn, and others. We still do not have the basics that Alta Vista offered before Hewlett Packard lost its mind and let them all go--the eight functions of shared directories, access and competency directories, budgets, maps, libraries, calendars, and forums are still scattered with no back office that cuts across disciplines.
08 Alternative Reality including Serious Games. Quote on page 277: "We have entered an age of alternative reality learning." I am a huge fan of the original World Game created by...Read more›

CompTIA A+ Complete Study Guide Review

CompTIA A+ Complete Study Guide
Average Reviews:

(More customer reviews)
Let me start off with just one word: Wow. When I was going through my training for A+, I would've loved to have had this book for studying. While I have not read the book cover-to-cover, I have gone through a lot of it and actually found myself being sucked in and reading more and more of it. Throw in the changes for the new A+ exam and I was blown away. The format of the book really works for someone getting a foot in the IT door by taking the A+ exam. Not only that, but as it stands now with the current trends, this (currently) very up-to-date tome is a good standby reference tool.
Having been only accustomed with the Mike Meyers universe of A+ study, this book was like walking into a different culture. It begins with my favorite part of the book: the Real World Scenarios. Often I found myself shuffling through the book looking just for these, some were a bit lacking but for the most part I found them to be relevant, insightful and in a lot of ways bringing the classroom to the reader. A great part of having any type of teacher is how they are able to impart to the student contextual knowledge, thereby putting everything in perspective. I think the Real World Scenario does a great job of accomplishing this. This also helps out in something friends and I have discussed that I happened to notice in the book.

A part that's almost worth the price of admission is the introduction, all in all, it's a mini study guide. I believe someone could use the intro for some last minute recognition and cramming. I believe this will come in handy for prospective A+ test takers.
As far as the negatives, while I have previously complimented much of the format used throughout, I do have a couple of qualms. For starters, when it comes to the OS-es, I think it would be a tad bit easier if it was separated by chapter. Command-line gets a chapter, 2K gets a chapter and XP gets a chapter. In some ways it seems a bit mashed together. The other les with the exam itself.
Instead of two clearly defined exams: OS and Hardware, there are 4 exams, but you only have to take 2: The "core" exam: Essentials and from there you can choose one of 3 tests. While I could go into more details, just looking at the outline and objectives, they all seem the same but just vary on the amount of customer interaction. It's nice to go the route of Microsoft and others with paths to certification, but it seems like it's more hype than anything else, almost irrelevant. Of course, without having ever taken the test, I can't be entirely sure. We'll just have to wait for the first victims to find out if I'm right or not.
All in all, the format is friendly and inviting. I thought that I would dread going through another A+ book, but I thought the approach was a breath of fresh air. It brings the classroom to the reader. The labs/exercises, scenarios, tips and notes do a marvelous job of getting the point across. I was even impressed by some of the technology covered. The various printers, scanner and media technology got some page time, so while it may, in some cases, give too much information, the book will stand the test of time on a shelf for easy reference.

Information Security : Principles and Practice Review

Information Security : Principles and Practice
Average Reviews:

(More customer reviews)
This text is an excellent introduction to the popular, important subjects of computer and network security, and is the best such text that I have yet seen. Professor Stamp offers clarity of presentation and a fluid, conversational style. There is an nice balance between comprehensive coverage and detailed analysis. Overall, I really like the structural organization, selection of topics, breadth of coverage, and level of difficulty. No special prerequisites are required to comprehend the basic ideas. However, readers with technical backgrounds will find a lot of material to challenge them. There are an abundance of illustrative figures, nice examples within the body of the text, and a wealth of good problems at the end of each chapter. The author provides excellent references for further study. Appendices delve into details concerning mathematical underpinnings and networking details.
The book is divided into four main parts: cryptography, access control, protocols, and software. The cryptography section introduces fascinating historical vignettes, then explores details of modern block and stream ciphers. The author includes an excellent chapter on cryptanalysis. He provides specific examples, using mathematics and Boolean logic. The access control section explains issues of policy and implementation, regarding authentication and authorization. The protocols section discusses specific mechanisms for secure exchange of confidential information. The final section describes management of software flaws and related security issues.

Virtual Teams: People Working Across Boundaries with Technology Review

Virtual Teams: People Working Across Boundaries with Technology
Average Reviews:

(More customer reviews)
I purchased this book because I was intrigued. In much of the work I do I am a member of "virtual" teams. That is, I often am some distance apart from the people I am working with.
I found the book to be a slow read, with nuggets of information separated by deserts of fluff. The first half of the book is filled with vague ramblings about how the information age has changed the way that teams work and with case studies that illustrate how the forming of virtual teams has helped various companies solve difficult problems.
In the second half, the book begins to pick up. In a chapter entitled "Teaming with People" the authors discuss team dynamics, including essential roles with a team, how teams form and which aspects of team dynamics are especially subject to the stresses of distance communication.
The authors suggest that the beginning and closing phases of most projects are the most stressful on team members and that extra effort be exerted at the beginning phase of the project to bring the core project team members together, even if they are geographically separated. This, say the authors, will help build interpersonal relationships that can hold the team together in times of stress.
There are several optimum team sizes. 3 to 5 is the size of a core team, 5 to 25 the size of a "team family" and 25 to 200 the size of a "team camp". In the authors' opinion, any team larger than 5 people will naturally divide into sub-teams.
The authors also point out the value of rewarding teams. Making teams compete, or making them completely independent of one another has little value for the company. Cooperative goals can encourage and motivate all of the teams, while competition can demoralize them.
Finally, the authors talk about starting up teams and provide a checklist of some elements such as a customer and a management sponsor which are essential to any team's success.
Overall, I found the book to have some good information on forming and maintaining teams, and what to do when those teams are not located in the same physical location. There is some fluff, I feel, and the book could easily be half its current length without sacrificing much.

E-Commerce Security: Weak Links, Best Defenses Review

E-Commerce Security: Weak Links, Best Defenses
Average Reviews:

(More customer reviews)
The title is ever so slightly misleading in that the topic is not electronic commerce as a whole, but the (admittedly most popular) Web segment of it. However, within this limit, the book does provide solid coverage and good advice for a whole range of issues.
Chapter one is a general introduction to the factors involved, looking at some recent "attacks" of various types, and then reviewing the client, transport, server, and operating system components to be examined in the remainder of the book. Client (generally browser) flaws are covered thoroughly in chapter two. The breadth of coverage even includes mention of topics such as the concern for privacy considerations with cookies. Active content is the major concern, with an excellent discussion of ActiveX (entitled "ActiveX [In]security"), a reasonably detailed review of the Java security model, and a look at JavaScript. Unfortunately, very little of this touches directly on e-commerce as such, except insofar as insecure client technology is going to make e-commerce a harder sell to the general public. While covering the transport of transaction information, in chapter three, Ghosh makes an interesting distinction between stored account systems (where you want to secure the transmission of identification data) and stored value systems (where the data, once transmitted, is useless to an eavesdropper). Many books concentrate on either channel security or electronic cash systems, so this comparison is instructive.
A server involves multiple programs, and may involve multiple machines. Server security can quickly become complex, and this is quite evident in chapter four. While a great deal of useful and thought-provoking information is presented, the complicated nature of the undertaking works against this chapter. Not all topics are dealt with thoroughly, or as well as the previous material was. Oddly, one issue not covered in depth is the firewall, which is handled very well in chapter five, with operating system problems. Ghosh sets up a classification scheme for OS attacks, illustrated by specific weaknesses in Windows NT and UNIX.
The book ends in chapter six with a call for certification of software, greater attention to security in all forms of software, and, interestingly, for greater use of component software. (From the jacket material, it appears that Ghosh is currently involved in the promotion of component software systems.)
Each chapter ends with a set of references. Unlike all too many books with bibliographies stuff with obscure citations from esoteric journals, the bulk of the material listed is available on the Internet. A separate section lists Web sites used in the text.
The various issues dealt with in the book are explained clearly, and generally present counsel on the best practices for secure online commerce. A compact but comprehensive guide to the current state of electronic transaction security.

Network+ Study Guide: Exam N10-003, Deluxe, 2nd Edition Review

Network+ Study Guide: Exam N10-003, Deluxe, 2nd Edition
Average Reviews:

(More customer reviews)
I just passed my Network+ exam today and I owe it all to David Groth for writting such an excellent book! I passed with a sccore of 801 out of 900 (89%) and I am only 15 YEARS OLD! I used this book plus Sybex Network+ Test Center, but I owe passing all to this one book. It is written very well, and makes everything easy to understand. All you need is this one book to pass the Network+ easily.
I read this book through about 3 times, first just cover to cover, second cover to cover highlighting important concepts, and the third time just read my highlights. After reading it about three times, I scored a 85% and 89% on the two included practice tests and felt like I was ready to go (most recommend getting at least 90% before trying though). I used two tests from the Virtual Test Center, but those questions were MUCH HARDER than the ones on the real test and didn't help much for the actual test.
This book is split into 10 detailed chapters, about everything you need to know to get started in a Networking carrer. I just complete my A+ Certification two months ago, and if it weren't for school I could have got my Network+ in less than a month. This book covers everything and more that you will see on the test (well, maybe except for 2 or 3 questions, but that's out of 65). The questions are all farily simple, but the hard part is that you need a 752 out of 900 (around 83%) to pass, which is much higher than other IT Certifications. But with this book, you will REALLY understand all the different things and as long as you memorize a few of the essentials (IEE groups, TCP/IP Addresses, TCP/IP Switches, etc.) you will easily pass. Just make sure to read the book a few times, because to get that 752 you NEED to know nearly all of the book.
In addition to the book being awesome, the 20 practice questions at the end of each chapter and the two COMPLETE practice tests on CD (one of them is also in the book) are really what prepare you. More than 3/4 of my test were questions that I had seen before from those practice questions. All the practice questions and detailed answers and really help you grasp the concepts and prepare for the test. There are over 500 questions included with the book, so it's all you need to pass (don't make the mistake I did and waste money on the Virtual Test Center). In addition, to get you started there is an Assesment Test, which really helps you see how much you have to study and in which areas.
Overall, the combination of an excellent book with over 500 practice questions that are nearly identical to the questions from the real thing, this makes for GREAT VALUE and necessary tool to pass the Network+ test. You can spend less than 40 bucks on this book with the practice questions and easily pass if you put your mind to it. Forget wasting $1000's of dollars on classes, this is all you need to succeed!

Voice over IP Security Review

Voice over IP Security
Average Reviews:

(More customer reviews)
I have been carrying this book around with me for a couple weeks now and had a couple long plane flights as well. This is a difficult book to review. The author clearly knows his stuff and the threat treatment is great. However, the material is all over the map. The subtitle talks about good security practices and the book is short on that to be candid. Bottom line, if you are considering a VoIP deployment or wondering how secure/robust your existing deployment is, this is a must read.
My favorite "I never thought of that" scenario in the book was a simple power outage. What if you have twenty thousand IP phones and the power drops . . . then when it is restored all 20k phones start banging the server causing an outage.

IPv6 in Practice: A Unixer's Guide to the Next Generation Internet Review

IPv6 in Practice: A Unixer's Guide to the Next Generation Internet
Average Reviews:

(More customer reviews)
Eventually we are all going to have to migrate on the Internet from IPv4 to IPv6. To be sure, this has taken longer than expected. But the sheer exhaustion of IPv4 addresses is bound to happen, and is a fundamental driver of the transition. So if you are a network programmer wondering about career trends, Stockebrand's book can be a useful consult.
He presupposes that you're already familiar with how IPv4 operates. You are then shown how IPv6 is much more powerful. Not just with the effectively infinite address space. But with how other drawbacks of IPv4 were addressed by the v6 designers. One of which is how v4 has no intrinsic Quality of Service. Current attempts to impose a QoS over v4 are crude and rather ad hoc. Whereas v6 has this built in as one of its fundamental properties.
Another v6 innovation is for Mobile IP, ie. nomadic computing. For this to be efficiently implemented, v4 falls short. But v6 gives a far simpler implementation. Thus Mobile IP may end up being one of the factors pushing for v6.

This book is a practical guide to IPv6 addressing Unix and network administrators with experience in TCP/IP(v4) but not necessarily any IPv6 knowledge. It focuses on reliable and efficient operation of IPv6 implementations available today rather than on protocol specifications. Consequently, it covers the essential concepts, using instructive and thoroughly tested examples, on how to configure, administrate, and debug IPv6 setups. These foundations are complemented by discussions of best practices and strategic considerations aimed at overall efficiency, reliability, maintainability, and interoperation.

Web Protocols and Practice: HTTP/1.1, Networking Protocols, Caching, and Traffic Measurement Review

Web Protocols and Practice: HTTP/1.1, Networking Protocols, Caching, and Traffic Measurement
Average Reviews:

You've built a B2C or B2B web service. You get great response time from your office, but there are times when your customers across the country report poor performance.
This book with help you understand the entire path between browser and web server and how Internet latency and intermediaries like Proxy servers add to transaction delay. This is the only source that I've seen that a) Defines HTTP 1.1 and b) describes the relationship between HTTP and the TCP/IP protocol stack, making recommendations on how to tune the stack to reduce the effect of latency.
You'll learn that many of TCP's flow control mechanisms were designed for FTP, Telnet and Rlogin and some default settings are not optimized, or even appropriate for HTTP.

Just as TCP/IP is a central protocol for the Internet, HTTP is a central protocol for the web. They are both critical for web networking. Web Protocols and Practice is the most authoritative and comprehensive guide to the Web's technical underpinnings. Authored by legendary AT&T Labs researcher Bala Krishnamurthy and renowned Web networking expert Jennifer Rexford, this book offers exceptionally thorough coverage of core Web protocols-including the most detailed discussion of HTTP /1.1 and its relationship to TCP/IP networking ever presented. The authors begin with a broad overview of the evolution of the Web, including its naming infrastructure, HTML document language, and HTTP message exchange protocol. Next, they introduce the inner workings of clients, proxies, and servers, as well as scripts, handlers, search engines, cookies, and authentication. The heart of the book is a detailed discussion of the core Web protocols DNS, TCP/IP, and HTTP. An essential resource for all networking and Internet professionals, and for all developers building Internet applications.

Principles and Practice of Information Security Review

Principles and Practice of Information Security
Average Reviews:

(More customer reviews)
This book is a must read for the corporate "C" Level. It covers risk abatement, strategies, and tactics to maintain the security of your corporate information as well as your customers and employees information. As a few companies have recently sustained damages in the hundreds of millions from attacks on their security - this book may have prompted them to close a few "loop holes" that allowed the breeches.
