Description

Web applications today are being hacked with alarming regularity by hacktivists, online criminals and nation states. Very frequently, it is the same prevalent security risks being exploited which is why the Open Web Application Security Project (OWASP) developed their list of Top 10 Most Critical Web Application Security Risks to help developers build more secure software. This course helps developers apply the Top 10 in ASP.NET using both web forms and MVC by walking through an overview of the risk, demonstrating how it can be exploited in .NET and then delving into the various approaches available to mitigate it by applying security in depth.
