Have you shifted left yet?
Outsider
What do you mean by 'shifted left'?
Insider
It means integrating security earlier in the development process, like during coding, not just after.
Outsider
Ah, I see how that helps catch bugs sooner!
Cultural Context
This greeting playfully references the core AppSec practice of shifting security activities earlier in software development to catch vulnerabilities early.

Take notes, create flashcards, or discuss concepts in online forums to reinforce learning. This step is crucial because it provides the mental framework for all future activities in the bubble. Evaluate your progress by explaining key risks in your own words and identifying them in sample code or applications.
2
Set Up a Safe Lab Environment
2-3 hoursIntermediate
Summary: Create a local environment for hands-on security testing using intentionally vulnerable apps.
Details: Application security is best learned by doing. Set up a safe, isolated lab environment on your computer using virtual machines or containers. Install intentionally vulnerable applications (such as demo web apps designed for learning security) to practice identifying and exploiting common vulnerabilities. This hands-on approach helps bridge the gap between theory and practice. Beginners often make the mistake of testing on live or production systems—always use dedicated, non-production environments to avoid legal and ethical issues. Follow setup guides carefully, and seek help from community forums if you encounter technical hurdles. This step is essential for developing practical skills and confidence.
