Cryptography : Theory and Practice Review

Cryptography : Theory and Practice
Average Reviews:

(More customer reviews)
As other people have pointed out, this is not a mathematics book, and it is not an algorithm (recipies) book. It could be a great book for people that are interested in learning these tools to actually use them, either in a research or product development context (something besides homework). Unfortunately, the number of typos, in key mathematical expressions AND PORTIONS OF THE EXPLANATIONS is staggering. Go to the author's web page and you will find that some chapters, like 4 for example, average more than one typo per page (and some of these 'typos' are full sentences, or math expressions that do not look like anything that is actually printed on the page). If you do not have that errata sheet handy, you will waste a lot of time trying to understand the text, or trying to solve the exercises. If you are trying to learn from this book, without attending a class and without the errata, you will simply give up. It is a real shame because it has all the makings of a great book.

Unauthorised Access: Physical Penetration Testing For IT Security Teams Review

Unauthorised Access: Physical Penetration Testing For IT Security Teams
Average Reviews:

(More customer reviews)
Unauthorised Access is nothing short of a manual for corporate espionage. Author Wil Allsopp, is a "penetration tester", a hired gun brought in by companies to find out how effective the security defences protecting their premises are.
While conventional penetration testing ("pentesting") involves remote hacking, typically through software vulnerabilities, physical pen-testers gain access to a company's offices or data centre with the goal of connecting to a restricted network, planting a bug or even an imitation explosive device
With ten years experience as a pen-tester, Allsopp offers superb insight into common methods used by criminals to manipulate employees, from phone calls to outright espionage. The chapter on social engineering, in particular, is guaranteed to spark paranoia and sleepless nights among even the most grizzled chief security officers.
Specific tactics he reveals include employing politeness, inducing fear, faking supplication, invoking authority, ingratiation and deference, and even sexual manipulation.
Another chapter details several successful pen-tests conducted by Allsopp and his team, including attacks on a UK power plant and a supercomputing facility conducting spatial modelling of nuclear explosions for the military. He also describes the antics of a pentester who bypassed the security of a large corporate by observing the uniform of the firm's security guard, then showing up the next day in identical costume, pulling rank and relieving the man of duty
The enjoyment Allsopp clearly derives from his work is reflected in his book; he writes with that particular tone of repressed glee common among white hat hackers. This, together with his tendency to adopt a Boy's Own adventure narrative style, makes the book very readable but occasionally somewhat glib. And at times it is hard to tell whether Allsopp is offering advice to the CSO, helping the reader start their own pen-testing company or trying to prove to a less salubrious readership how clever he is.
Indeed, many of the techniques described in Unauthorised Access are open to abuse. Allsopp gives the excuse that "the bad guys already know", before urging the reader to consider taking up lock picking as a rewarding hobby.

The first guide to planning and performing a physical penetration test on your computer's security
Most IT security teams concentrate on keeping networks and systems safe from attacks from the outside-but what if your attacker was on the inside? While nearly all IT teams perform a variety of network and application penetration testing procedures, an audit and test of the physical location has not been as prevalent. IT teams are now increasingly requesting physical penetration tests, but there is little available in terms of training. The goal of the test is to demonstrate any deficiencies in operating procedures concerning physical security.
Featuring a Foreword written by world-renowned hacker Kevin D. Mitnick and lead author of The Art of Intrusion and The Art of Deception, this book is the first guide to planning and performing a physical penetration test. Inside, IT security expert Wil Allsopp guides you through the entire process from gathering intelligence, getting inside, dealing with threats, staying hidden (often in plain sight), and getting access to networks and data.
Teaches IT security teams how to break into their own facility in order to defend against such attacks, which is often overlooked by IT security teams but is of critical importance
Deals with intelligence gathering, such as getting access building blueprints and satellite imagery, hacking security cameras, planting bugs, and eavesdropping on security channels
Includes safeguards for consultants paid to probe facilities unbeknown to staff
Covers preparing the report and presenting it to management

In order to defend data, you need to think like a thief-let Unauthorised Access show you how to get inside.

Principles of Information Security Review

Principles of Information Security
Average Reviews:

(More customer reviews)
This book does provide a broad overview of the concepts of information security. Whatever good information this book does provide is, to some extent, offset by three problems: First, the book is filled with many, many typographical errors. While reading the book, I constantly found myself going back and trying to determine what the writer meant by many of the mangled sentences (or pieces of sentences) in the book. Second, there are a few errors in information. Finally, there are areas where important explanations or details about concepts are completely omitted. The writers needed to do some additional work and editing to make the book's portrayal of many of the concepts it covers clearer and more comprehensive.
There are plenty of free online resources (NIST's Computer Security Resource Center, for example) that would be better places to learn about information security than this text.

Computer Forensics: Principles and Practices Review

Computer Forensics: Principles and Practices
Average Reviews:

(More customer reviews)
I liked the book. It opened my eyes to a lot of areas I knew nothing about. I can understand previous reviewers who weren't happy with the book. Some material is dated and it isn't an All-In-One text on the subject. But, if you're just starting out, like me, it is a great first read. Also, by actually doing the Projects in the back of each chapter, especially Chapter 7 and 8, you'll get a ton of information on very useful forensic topics and techniques including, software that you can download and use for free, etc...
If some websites for the software don't exist anymore, Google the names and the info on where to get it will come up. If you are into learning forensics, having to find this info shouldn't discourage you, otherwise you're learning the wrong subject.
I had a blast with this book and it really wet my appetite to learn more. What more could you want from an introductory text on any subject.

Network Security Bible Review

Network Security Bible
Average Reviews:

(More customer reviews)
This is a great book; it goes in great detail about security in all aspects of the computer industry. However it lacks one critical aspect, how do I do that? Like all network and computer professionals, I do not know everything, so when you tell me I should do something a certain way I'd hope that you will also tell me how to do it. With this book I found myself saying, maybe they will tell me what to do later, over and over, never happens. If you want to buy a book that's a reference manual, this is the one to get. If you are looking for a "how to" as well as a "what to look for" book, consider looking elsewhere.
