Résumé

This book is much more than a wake-up call. It is also an eye-opener. Even for those who are already awake to the problems of Web server security, it is a serious guide for what to do and what not to do, with many well-chosen examples. The set of fundamental rules is highly relevant.

Peter G. Neumann, Author of Computer-Related Risks,and moderator of the Internet Risks Forum (risks.org).

This concise and practical book will show where code vulnerabilities lie and how best to fix them. Its value is in showing where code may be exploited to gain access to - or break - systems, but without delving into specific architectures, programming or scripting languages or applications. It provides illustrations with real code.

Innocent Code is an entertaining read showing how to change your mindset from website construction to website destruction so as to avoid writing dangerous code. Abundant examples from susceptible sites will bring the material alive and help you to guard against:

SQL Injection, shell command injection and other attacks based on mishandling meta-characters
bad input
cross-site scripting
attackers who trick users into performing actions
leakage of server-side secrets
hidden enemies such as project deadlines, salesmen, messy code and tight budgets

All web programmers need to take precautions against producing websites vulnerable to malicious attack. This is the book which tells you how without trying to turn you into a security specialist.
