πŸ”‘ Key Concepts You'll Master

Defense in Depth

Multiple layers of security controlsβ€”like the seven walls of Constantinople that held for 1,000 years. If one layer fails, others still protect.

Shared Responsibility Model

In cloud computing, security is a partnership. The provider secures the cloud; you secure what's IN the cloud. Misunderstanding this caused the 2019 Capital One breach.

Zero Trust Principle

"Never trust, always verify." Inspired by Google's BeyondCorp after the 2009 Operation Aurora attack. Trust nothing, verify everything, assume breach.

Least Privilege Access

Users get only the minimum permissions needed. As Confucius might say: "Give a person the keys they need, not the keys they want."

πŸ“‹ Featured Case Study: Capital One Data Breach (2019)

A former AWS employee exploited a misconfigured Web Application Firewall (WAF) to access 100 million customer records. This module teaches you exactly what went wrong and how proper cloud security controls could have prevented it.
