.NET provides unprecedented flexibility and productivity to web application developers. Many applications allow access to critical and confidential resources and this has made them popular targets for attack. Application developers are responsible for understanding the limitations of .NET and adopting best practices to ensure that their code is secure.
This course aims to provide the knowledge and resources required to improve the security of Web applications developed using .NET. This course is designed to educate developers on the skills necessary to build and deploy secure .NET applications following a Secure Development Lifecycle (SDL) process.
It is recommended that participants on the Web Application Secure Coding in .Net have completed the Web Application Security Essentials course. Please see Related Training at the end of this page.
The course is designed for:
• Software Developers
• Quality Assurance professionals
• System Architects
• Information Security Professionals
The course is aligned with the OWASP Top 10, a world-renowned reference document which describes the most critical web application security flaws.
The topics covered include:
The course combines theory and hands-on practical exercises. The participants learn to identify vulnerabilities in a purposely-developed .Net application and fix them using secure coding best practices. This provides an ideal ‘real-life’ opportunity to exploit these vulnerabilities using different open source tools and techniques in a safe environment.
