Course Outline
IT Security and Secure Coding Foundations
- Fundamentals of threat modeling: STRIDE, attack surfaces, and privilege escalation vectors
- Integrating secure SDLC practices: shifting left, threat-aware design reviews, and defense-in-depth
- Applying the principle of least privilege, defense by contract, and secure default configurations
- Workshop: Mapping a .NET microservice to a threat model and identifying architectural controls
Web Application Security in ASP.NET
- Understanding the ASP.NET request pipeline, middleware execution order, and filter interception points
- Assessing HTTP protocol risks: header injection, request smuggling, and CORS misconfigurations
- Best practices for session management, state persistence, and cookie security
- Securing remote procedure calls and patterns for consuming external APIs
- Lab: Exploiting and patching a vulnerable middleware chain within a sample ASP.NET application
.NET Security Architecture and Built-in Services
- Overview of the CLR security model: evidence, permissions, and the evolution of Code Access Security (CAS)
- ASP.NET Core Identity, authentication schemes, and token-based security (JWT, OAuth2, OpenID Connect)
- Data Protection API: encryption, key rotation, and secure data serialization
- Cryptographic primitives in .NET: RNG, hashing, symmetric/asymmetric encryption, and signature validation
- Lab: Implementing secure token issuance, key rotation, and data protection across a microservice boundary
Common Coding Errors, Vulnerabilities, and Mitigation
- Deserialization attacks, ViewState tampering, and string termination/overflow pitfalls in .NET
- Configuration drift: managing web.config/appsettings.json, preventing environment variable exposure, and secret management
- Injection vectors: SQL, command, XSS, and LDAP vulnerabilities in C# data access and routing
- Risks associated with insecure defaults, hardcoding, and improper error handling leading to information leakage
- Lab: Reverse-engineering a vulnerable .NET module, applying secure patterns, and validating fixes with static/dynamic analyzers
Security Testing, Validation, and Continuous Improvement
- Static Application Security Testing (SAST): using Roslyn analyzers, Security Code Scan, and integrating into CI/CD
- Dynamic Application Security Testing (DAST): leveraging OWASP ZAP, Burp Suite workflows, and automated scanning
- Runtime protection: Application Guardrails, memory safety practices, and secure logging/auditing
- Patch management, dependency tracking, and responding to .NET/ASP.NET security advisories
- Lab: Building a pre-commit and pipeline security gate for a .NET solution
Knowledge Sources and Secure Development Ecosystem
- Official Microsoft security guidance, .NET security documentation, and ASP.NET hardening references
- Navigating CVE databases, advisory feeds, and responsible disclosure workflows for open-source dependencies
- Secure library ecosystems: PGP, crypto-ops, authentication scaffolds, and compliant cryptography
- Establishing internal secure coding standards, developer enablement, and security champion programs
- Workshop: Curating a personalized secure development toolkit and establishing ongoing monitoring practices
Requirements
- Strong working knowledge of C# programming and the fundamentals of the .NET framework
- Familiarity with ASP.NET web development (including Razor Pages, MVC, or Minimal APIs)
- Understanding of core HTTP, routing, and web server concepts
- No prior security certification is required, though production coding experience is expected

Very good to understand how a hacker would potentially analyse sites for weakness and tools they might employ .

the corny jokes. Love the first 2 day session because of the labs.
Kevin Galacgac - Human Edge Software Philippines, Inc.
Course - .NET, C# and ASP.NET Security Development
The trainer is really connecting with us and making sure that nobody left out of the current topic. Explains well to each topic and provides an example that is easy to understand.
