xlviImproving Web Application Security: Threats and CountermeasuresForeword by Erik OlsonFor many years, application security has been a craft learned by apprenticeship.Unfortunately, the stakes are high and the lessons hard. Most agree that a betterapproach is needed: we must understand threats, use these hard lessons to developsound practices, and use solid research practices to provide layers of defense.Web applications are the portals to many corporate secrets. Whether they sit onthe edge of the lawless Internet frontier or safeguard the corporate payroll, theseapplications are a popular target for all sorts of mischief. Web application developerscannot afford to be uncertain about the risks to their applications or the remedies thatmitigate these risks. The potential for damage and the variety of threats is staggering,both from within and without. However, while many threats exist, the remedies canbe crystallized into a tractable set of practices and procedures that can mitigateknown threats and help to guard against the next unknown threat.The .NET Framework and the Common Language Runtime were designed and builtwith these threats in mind. They provide a powerful platform for writing secureapplications and a rich set of tools for validating and securing application assets.Note, however, that even powerful tools must be guided by careful hands.This guide presents a clear and structured approach to dealing with Web applicationsecurity. In it, you will find the building blocks that enable you to build and deploysecure Web applications using ASP.NET and the .NET Framework.The guide begins with a vocabulary for understanding the jargon-rich language ofsecurity spoken by programmers and security professionals. It includes a catalog ofthreats faced by Web applications and a model for identifying threats relevant to agiven scenario. A formal model is described for identifying, classifying, andunderstanding threats so that sound designs and solid business decisions can bemade.The text provides a set of guidelines and recommended design and programmingpractices. These guidelines are the collective wisdom that comes from a deep analysisof both mistakes that have been made and mistakes that have been successfullyavoided.The tools of the craft provided by ASP.NET and the .NET Framework are introduced,with detailed guidance on how to use them. Proven patterns and practices for writingsecure code, using data, and building Web applications and services are alldocumented.Sometimes the desired solution is not the easiest path. To make it faster and easier toend up in the right place, the authors have carefully condensed relevant sample codefrom real-world applications into building blocks.
Forewords xlviiFinally, techniques for assessing application security are provided. The guidecontains a set of detailed checklists that can be used as guidelines for newapplications or tools to evaluate existing projects.Whether you’re just starting on your apprenticeship in Web application securityor have already mastered many of the techniques, you’ll find this guide to be anindispensable aid that will help you build more secure Web applications.Erik OlsonProgram Manager, ASP.NET Product TeamMicrosoft Corp.
