IAM Policies Hands-On

On this lecture, we explore the practical application of IAM policies in AWS, focusing on how to create and manage policies effectively.

Key Takeaways​

  • User Permission Management: The lecture illustrates how user permissions are managed through group memberships, using the example of a user, Rendy, who initially has administrator access. User Permissions
  • Effects of Group Membership: When removed from the admin group, Rendy experiences a loss of permissions, demonstrating how group affiliation impacts access rights. Access Loss
  • Restoring Access: By adding the IAMReadOnlyAccess policy to Rendy, I regain certain permissions, allowing me to view IAM resources without the ability to create new ones. Restoring Access
  • Flexibility in IAM: Users can inherit permissions from groups, and multiple policies can be attached to a single user, showcasing the flexible nature of IAM management.
  • Common IAM Policies: The lecture discusses key policies like AdministratorAccess for full access and IAMReadOnlyAccess for limited read and list actions, along with their JSON representations.
  • Custom Policy Creation: It covers how to create custom policies using both a visual editor and JSON editor, enabling tailored permissions based on specific needs. Visual Editor JSON Editor
