The Microsoft Open Source Programs Office, led by Director Jeff McAffer, aims to streamline security processes through a mantra of "eliminate, automate, delegate." This approach has resulted in 99% of open source usages being automatically detected and reviewed with no human intervention. However, despite automation, humans are still involved, and it's essential to have a security plan in place to address potential vulnerabilities. Microsoft's two-level approach to security includes active development and incident response teams, which cover most use cases. The company also debuts ClearlyDefined.io to crowdsource license data and improve open source stewardship, emphasizing the importance of treating open-source components like one's own code and engaging with project teams to ensure security and integrity.
