Secure .Net Web Application Development Lifecycle

The Secure .Net Web Application Development Lifecycle (SDL) course focusses on enabling .Net developers to build secure web applications, incorporating essential security elements into the applications, from the development to deployment stage and beyond. In addition to a basic level of secure programming skills, developers will also learn about the right practices and processes for the entire software development lifecycle.

During this course, developers will initiate attacks and provide defenses, while also learning about the right practices and processes to be able to code secure web applications, including XML processing, rich interfaces, as well as RESTful and SOAP-based web services. At the end of the program, students will be equipped with the ability to recognize both potential as well as real security vulnerabilities and employ the right defense measures to overcome them, and also test the adequacy of those defenses. This course will introduce developers to the most common security vulnerabilities encountered in web applications today, and enable them to examine each vulnerability from a .Net perspective. Further, developers will learn to describe the threat and attack mechanisms, recognize associated vulnerabilities, and consequently, design, implement, and test effective defenses.
