Modern .NET development is a race for velocity. We are writing less "original" code than ever, instead relying on a massive ecosystem of NuGet packages and the siren song of AI-generated snippets from GitHub Copilot. But this speed comes with a hidden tax: a massive expansion of your attack surface. If you didn't write every line of code in your assembly, how can you truly trust it?

This session is a practical, demo-heavy guide for .NET developers who want to take ownership of security without slowing down. We will move beyond theory to dissect the three primary vectors of modern code risk: vulnerable dependencies, "hallucinated" security flaws in AI suggestions, and systemic configuration gaps.

You will leave this session with a battle-tested playbook for "Shifting Left." We’ll explore how to automate Software Composition Analysis (SCA) directly in the CLI, how to treat AI as a "junior dev" with a code review framework, and how to implement Static Application Security Testing (SAST) quality gates that stop vulnerabilities before they hit your main branch. Stop being a passive consumer of code and start being a security champion.
