AWS FAQ: IAM

IAM (Identity and Access Management) is AWS's system for managing access to resources securely. It allows you to define who can do what on which resources.

🗺️ Step-by-Step Instructions:

1. Create IAM users, groups, and roles via the AWS Console.
2. Attach policies defining permissions.
3. Enable MFA and enforce least privilege access.

📥 Example Input:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "*"
    }
  ]
}

🏆 Expected Output:

User with full access to all S3 resources.

{ "Action": "ec2:Describe*", "Effect": "Allow", "Resource": "*" }
