What I Learned

  • - Users, groups, roles, and policies are the core IAM building blocks.
  • - Roles are better than long-term access keys when AWS services need to talk to each other.
  • - Least privilege means giving only the permissions needed for a task.

Why It Matters

IAM is one of the most important cloud security controls because permission mistakes can expose an entire AWS account.

Mistakes and Challenges

  • - Separating trust policies from permission policies took repetition.
  • - Policy examples were easy to copy but harder to explain line by line.

What I Built/Tested

  • - Created an IAM policy for limited S3 access.
  • - Reviewed how an IAM role can be attached to an AWS service.
  • - Tested what happens when a permission is missing.

Next Steps

  • - Practice writing smaller custom policies instead of using broad managed policies.
