Getting Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!

Challenge
Enhancing Password Protection with BCrypt
You'll review a login microservice that uses weak MD5 password hashing. Then, you'll examine its secure remediation using BCrypt, and learn how to effectively protect user passwords against common attacks.
-
Challenge
Mitigating Brute-Force Attacks with Rate Limiting
You'll examine how rate limiting was added to a Spring Boot login endpoint to defend against brute-force attacks. You will see how Bucket4j and Ehcache are used to secure the authentication process effectively.
