.Net Secure Coding Camp | Attacking and Securing .Net Web Apps (for .Net Core / Latest Edition)

Objective

Students who attend Attacking and Securing .Net Web Applications will leave the course armed with the skills required to recognize actual and potential software vulnerabilities and implement defenses for those vulnerabilities.  This course begins by developing the skills required to fingerprint a web application and then scan it for vulnerabilities and bugs. Practical labs using current tools and techniques provide students with the experience needed to begin testing their own applications. Students also gain a deeper understanding of how attackers probe applications to understand the runtime environment as well as find potential weaknesses. This course the introduces developers to the most common security vulnerabilities faced by web applications today. Each vulnerability is examined from a .Net perspective through a process of describing the threat and attack mechanisms, recognizing associated vulnerabilities, and, finally, designing, implementing effective defenses. 

Audience Profile

This is an intermediate -level .Net secure programming course, designed for experienced C# / ASP.Net developers who wish to get up and running on developing well defended software applications.

Prerequisites

Familiarity with C# / ASP.Net is required and real world programming experience is highly recommended. Ideally students should have approximately 6 months to a year of .Net development practical experience.
