Cloud security is more than just protecting resources. It’s also about controlling who can access what, and what they’re allowed to do.

In this module, I explored AWS Identity and Access Management (IAM) and its role in securing cloud environments.

Here are four key concepts I learned:

🔹 IAM Users: Identities for individuals or applications that need access to AWS.

🔹 IAM Groups: Collections of users that can share the same permissions.

🔹 IAM Roles: Identities with permissions that can be assumed by trusted users or services when needed.

🔹 IAM Policies: Documents that define permissions—what actions are allowed or denied on which resources.

One principle that stood out to me was the principle of least privilege: granting only the permissions necessary to perform a task.

My biggest takeaway?

Security isn't just about keeping people out. It's about ensuring the right people and services have the right access.

Module 4: Done. 🚀🔐
