Overview

This course is designed to train experienced .Net developers in .Net security to enable them to build secure web applications, incorporating essential security elements into the applications, from the development to deployment stage and beyond. Participants will thoroughly examine best practices for coding .NET web applications effectively. They will be trained to code secure web applications, including on concepts like XML processing, rich interfaces, as well as RESTful and SOAP-based web services. Participants will repeatedly attack and then defend various assets associated with a fully-functional web application.

What You'll learn

  • Recognize potential and real security vulnerabilities, employ the right defense measures and test the adequacy of those defenses
  • Understand the most common security vulnerabilities encountered in web applications today and enable them to examine each vulnerability from a .Net perspective
  • Describe the threat and attack mechanisms, recognizing associated vulnerabilities, and consequently, design, implement and test effective defenses
