You've heard the nasty stories about PHP sites being wiped off the web by evil hackers? Sadly it's not scare-mongering as it does happen, and as much as we love PHP it needs proper security to keep your site safe from harm. Plenty of PHP books have the odd chapter on security but at last O'Reilly have published a whole volume dedicated to the cause, with all the code you'll need to keep everything in order. Each chapter covers a different aspect of the application, from form processing to database programming and session management. Written in a straight forward style, it's ideal for every PHP user, but at GBP20 you might expect a little more than just 100 pages." .NET, November 2005 "If you write PHP scripts, get a copy" - Alain Williams, news@UK, March 2006
Being highly flexible in building dynamic, database-driven web applications makes the PHP programming language one of the most popular web development tools in use today. It also works beautifully with other open source tools, such as the MySQL database and the Apache web server. However, as more web sites are developed in PHP, they become targets for malicious attackers, and developers need to prepare for the attacks. Security is an issue that demands attention, given the growing frequency of attacks on web sites. "Essential PHP Security" explains the most common types of attacks and how to write code that isn't susceptible to them. By examining specific attacks and the techniques used to protect against them, you will have a deeper understanding and appreciation of the safeguards you are about to learn in this book. In the much-needed (and highly-requested) "Essential PHP Security", each chapter covers an aspect of a web application (such as form processing, database programming, session management, and authentication). Chapters describe potential attacks with examples and then explain techniques to help you prevent those attacks.Topics covered include: preventing cross-site scripting (XSS) vulnerabilities; protecting against SQL injection attacks; and, complicating session hijacking attempts. You are in good hands with author Chris Shiflett, an internationally-recognized expert in the field of PHP security. Shiflett is also the founder and President of Brain Bulb, a PHP consultancy that offers a variety of services to clients around the world. Alle Produktbeschreibungen

Chris' book is great. It's chocked full of easy to understand explanations and little five line code fragments to demonstrate what he's explaining. Sure enough, if you read the whole thing, you'll understand the essentials of PHP Security. Hey - perhaps that explains the title?
Do I need this book if my company already uses web scanning security software? Yes - you won't understand the problems that those products identify if you don't understand PHP security basics. If you don't understand reported errors, You'll be tempted to ignore or suppress warnings that you don't understand. Chris' book will give you the knowledge that you need in a few easy to follow pages.
There are a few ommissions. They include:
OMISSION #1: The book should mention somewhere that many of the security vulnerabilities it describes are not unique to PHP - especially big ones like cross-site scripting and SQL injection. While PHP has some vulnerabilities that other languages do not (and vis-versa), Java, C#, Ruby, and all the other server-side languages can also be attacked with cross-site scripting, SQL injection, session spoofing, cookie theft, backdoor URLs, etc., etc.
OMISSION #2: The book would have benefited from the addition of a page of system administration best practices to improve security rather than confining itself only to coding best practices. For example, it's easy for developers to accidentally open security holes by making very small changes to the PHP.ini file. A good best practice is to use the operating system to restrict access to that file in the production environment. Or it would have good to see Chris distill role-based security administration policies, logging, or remote procedure call policies down to just the most important principles. He has a knack for filtering out the noise, and if he had added that additional 86th page, I swear I would have read it too.
OMISSION #3: It's worth mentioning how modular design has a very big impact on the number of vulnerabilities inside an application. This is especially important for PHP, because PHP code is often a little more haphazard than code written in other languages - primarily because of the culture that surrounds PHP but also for a few other reasons (we cover those reasons in the PHP Chapter of our own book on the strengths and weaknesses of various technologies).
These criticisms are very minor. The book is short, easy-to-read, and filled with information that is absolutely essential to know if you are to responsibly deploy a server-side PHP application. Look at the table of contents. If you're not familiar with those terms, you'd better get the book.

It was a shorter book than I was expecting (yes, that's my goof for not noticing the page count when I purchased it) however I'm glad that I didn't notice that fact before purchasing otherwise I might have overlooked it as more of a reference book rather than a teaching book. I was very happy with the book and would recommend it to anyone interested in some solid best practices for PHP security.
At best, the whole book feels like a quickly written computer magazine article, not a good, comprehensive book.
Not worth the money. Just do a search for "PHP Security" on the internet and read a few articles and you will know more than this book.
