Secure defaults and least privilege

Most breaches exploit something that was left open rather than something clever. Default deny, then grant the narrow thing that is needed.

What this lesson covers

• Default to deny and grant explicitly
• Scope credentials to the minimum they need
• Reduce attack surface by removing unused paths

This lesson sits in Thinking About Threats, part of Practical Web Security. It assumes what came before it and leads directly into the next lesson in the module.
