This document summarizes a presentation on machine learning-based identity protection in Azure Active Directory. The key points are:
1. Azure AD uses machine learning to analyze over 10TB of logs and data from various sources to classify users as "seems good" or "seems bad" in real time.
2. The machine learning classifier is continually improved by analyzing outcomes when users are later determined to be malicious or legitimate. Code updates are deployed to improve classification accuracy.
3. A case study example describes how Azure AD detected an education sector attack through anomalous password lockout activity and suspicious IP patterns that differed from normal in-country traffic.
