Learn to give a reporting workflow the access it needs and test that unrelated operations are denied. AWS Identity and Access Management (IAM) controls which identity may perform an action on a resource.
Five guided labs cover identity policies, group membership, temporary role credentials, an S3 resource policy and Access Denied diagnosis. The independent challenge keeps a report worker functioning while removing excessive access.
What You Will Learn
- Write a reader policy scoped to the required report
- Manage team access through IAM group membership
- Use temporary credentials from an IAM role
- Distinguish who may assume a role from what its session may do
- Protect an S3 bucket with a resource policy
- Diagnose access failures by checking caller identity and policy scope
- Keep input-read and output-write behavior working while removing unrelated permissions
Who This Course Is For
This course is for AWS beginners who have practiced file storage and now want to understand and troubleshoot resource permissions.
Prerequisites: Complete Get Started with AWS on LabEx, the required preparation lab in AWS Foundations for Beginners, and complete Foundations and S3 file operations. You should recognize AWS CLI commands and resource ARNs.
Learning environment: All activities run in a provided browser-based LabEx Linux environment. Use Terminal for AWS CLI commands and AWS View, next to Terminal, to inspect the same resource and application state. Tools and the connection are prepared; you do not need a personal AWS account or access keys. Each lab starts independently in a fresh VM.
Frequently Asked Questions
How are authentication and authorization different?
Authentication identifies the caller; authorization decides what that caller can do. Credentials prove an identity, while policies grant or restrict access. Changing CLI profiles changes the caller, so confirm identity when diagnosing a denial.
Are IAM users the default access pattern for production?
Human access should normally use federation, commonly through IAM Identity Center; workloads should normally receive temporary role credentials. Protect the root identity, use it only for required tasks and enable MFA. User and group exercises teach existing IAM systems. Protect long-lived keys from code, logs and screenshots. See AWS IAM security best practices.
How do I know a policy works?
Test permitted requests and forbidden operations. A policy document alone is insufficient, and a connection failure does not prove authorization or cleanup. Withdraw permissions and remove only owned exercise resources after functional checks.
Does this course cover every policy type?
No. Cross-account access, organization service control policies, permissions boundaries and a full conditions engine are outside this introductory scope. Continue with DynamoDB, logs, Lambda and the private API path.
