Mã nguồn an toàn trong C# & .NET

Welcome to Secure Code in C# & .NET, your comprehensive guide to building secure, compliant, and resilient software in the Microsoft .NET ecosystem. This course takes you far beyond theory—every module combines hands-on coding labs, real-world attack simulations, and AI-assisted security workflows using GitHub Copilot and modern .NET features.

Whether you’re developing enterprise APIs, web apps, microservices, or cloud-hosted applications, this course will teach you how to think like an attacker and code like a security engineer.

What You’ll Learn

1. Foundations of Secure Software Development

• Understand the Secure Software Development Lifecycle (SSDLC) and threat modeling in C#.

• Apply OWASP Top 10 principles directly to .NET codebases.

2. Secure Authentication and Authorization

• Implement secure login flows using .NET Identity, JWT tokens, OAuth 2.1, and OpenID Connect.

• Enforce multi-factor authentication (MFA) and role-based access control (RBAC).

• Prevent broken access control and privilege escalation using horizontal and vertical access policies.

3. Secret Management and Configuration Security

• Safely store and access application secrets

• Avoid secret leaks in GitHub and CI/CD pipelines.

• Automate configuration protection in local, staging, and production environments.

4. Data Security and Compliance

• Protect data at rest and in transit with AES encryption, TLS, and Transparent Data Encryption (TDE).

• Implement GDPR, CCPA, and HIPAA compliance practices.

• Prevent excessive data exposure and ensure logging without leaking PII.

5. User Input Validation & Injection Prevention

• Master validation and sanitization using Data Annotations, custom validation attributes, and schema validation.

• Block SQL injection, command injection, and XSS attacks.

• Implement allowlists, regular expressions, and secure deserialization patterns.

7. Secure Build and Deployment Pipelines

• Configure secure build processes with GitHub Actions, Azure DevOps, and Docker.

• Perform dependency checks, supply chain validation, and code signing.

• Apply the principle of least privilege in hosting environments and infrastructure.

8. Secure AI-Assisted Development with GitHub Copilot

• Configure Copilot for secure coding—block public code matches and filter unsafe suggestions.

• Use Copilot Chat and Agent Mode to find, fix, and prevent vulnerabilities.

• Integrate AI code reviews and Copilot Business features for enterprise-level assurance.

Technologies and Tools Covered

• .NET, C#, Identity

• Entity Framework Core, Azure Key Vault, GitHub Copilot

• JWT, OAuth2, OpenID Connect, MFA

• Security Code Scan, OWASP Dependency Check, DPAPI

• Visual Studio, GitHub Actions, Azure DevOps

Why Take This Course

Because secure code is no longer optional. From data breaches to AI-generated code vulnerabilities, modern developers must learn to integrate security, compliance, and automation into every line of C# they write. By the end of this course, you’ll not only write secure, production-ready code, but you’ll also know how to use AI tools like GitHub Copilot to prevent vulnerabilities before they ship.

Master the art of writing Secure Code in C# & .NET — powered by AI, protected by best practices, and built for the future.
