Certified C# and Web application security

This comprehensive three-day course empowers developers with the skills to secure C# and ASP.NET web applications against common vulnerabilities and advanced cyber threats. Participants will explore core IT security principles, secure coding practices, and .NET-specific security measures. Key topics include SQL injection, cross-site scripting (XSS), authentication flaws, and insecure deserialization, with a focus on how they affect ASP.NET applications.

The course also delves into the .NET framework’s security architecture, emerging issues, and cryptographic techniques. Through hands-on exercises, participants will gain practical experience in applying secure coding practices to real-world scenarios.

By the end of this course, participants will be able to:

• Identify and mitigate common web vulnerabilities affecting .NET applications, including OWASP Top Ten issues.
• Apply secure coding practices in C# to prevent injection attacks, XSS, and insecure deserialization.
• Utilise the security features of the .NET framework to enhance application security.
• Strengthen authentication, session management, and access control in ASP.NET applications.
• Conduct vulnerability assessments using tools like static code analysis and penetration testing frameworks.
• Apply secure coding principles and follow key guidelines from industry standards such as OWASP and SEI CERT.

• General C# development knowledge.
• Familiarity with web application concepts is beneficial but not mandatory.
