What you'll learn

Python applications often communicate with remote services, browsers, and logging pipelines, and each communication path can introduce security risk. In this course, Secure Communications for Python, you’ll gain the ability to apply practical controls that protect these communication paths. First, you’ll explore how TLS certificate validation works in Python HTTP clients and how to preserve validation in Requests and urllib3. Next, you’ll discover how HSTS and CORS affect browser-facing response behavior and how to configure and verify those controls in Python web applications. Finally, you’ll learn how sensitive data can leak through tracebacks and logs, and how structured logging and redaction can reduce that risk. When you’re finished with this course, you’ll have the skills and knowledge needed to secure common Python communication patterns and verify that those controls are working as intended.
