CLOUD / A CONCEPT NOTE
Shared Responsibility
what the cloud won't secure for you
Overview · mechanism
pitfall · examples
01 / THE SHORT VERSION
The idea in a few sentences.
The cloud provider secures the infrastructure (datacenter security, physical servers, hardware patching). You secure what's inside (operating system configs, application code, database access, and IAM policies).
02 / FOLLOW THE MECHANISM
How security responsibility separates
Provider duties
AWS secures physical datacenters against intrusions and maintains healthy hypervisor systems.
Your duties
you write firewall rules, restrict IAM roles, and patch operating system software.
Security breach
if a hacker gets access via a public S3 bucket or weak password, responsibility lies solely with you.
04 / COMMAND NOTES
Read the command, then the result.
Inspect the flags and arguments before trying an example. Snippets can need local setup, replacement values, or resources in your own environment.

Could you explain Shared Responsibility to a teammate?
Try it out loud in two sentences: what it is, and the one detail that changes the picture. If you stall, the gap is the part to reread.
