Discover how to protect your applications from attacks and bad data! During this course, you'll learn how to identify and defend your C#+ applications from potential risks and control user input to reduce the possibility of bad data entry. Topics include how to address potential UI application risks, such as buffer overflows, code injection attacks, formatted string attacks, and DLL hijacks. Next, specify how to handle bad data in your C# applications, and learn how to constrain user input to keep out malicious entries that can break your code. From there, you will learn how to validate user input through regular expressions, and write effective exception handlers. Finally, as a review exercise, you will create a C#/ASP.NET application that runs a contact page that applies defensive code and requires validated user input.
