Certified C# and Web application security Training in France

  • Learn via: Classroom / Virtual Classroom / Online
  • Duration: 3 Days
  • Level: Intermediate
  • Price: From €5,317+VAT

This intensive 3-day course equips developers with the knowledge and hands-on experience to secure C# and ASP.NET web applications.
It focuses on OWASP Top 10, .NET security features, and industry standards (SEI CERT, Saltzer & Schroeder).

Key topics include:

  • SQL Injection

  • Cross-Site Scripting (XSS)

  • Insecure Deserialization

  • Authentication and Session Management

  • Cryptography and Secure Framework APIs

Participants engage in hands-on labs to identify, exploit, and remediate vulnerabilities in real-world scenarios.


Regulatory Compliance (BDDK)

Fully aligned with the
Regulation on Banks’ Information Systems and Electronic Banking Services (Articles 20, 22, 23, 25).

This ensures the course meets secure software development and testing obligations required for banks and financial institutions.
