Reviewing and Modifying Roles and Permissions in Google Cloud IAM
Introduction: Understanding Google Cloud IAM Roles and Permissions
Google Cloud Identity and Access Management (IAM) is a critical component for
securing cloud resources by providing administrators the ability to control who can
take actions on specific resources. This system offers a unified and straightforward
interface to manage access across all Google Cloud services consistently. For
organizations with intricate structures, IAM delivers a centralized view of security
policies throughout the entire organization, complete with built-in auditing to
facilitate compliance. The fundamental principle behind IAM is simplicity, allowing
for the efficient management of resource permissions with a high degree of
automation. It allows for mapping job functions to groups and roles, ensuring users
are granted access only to what they need to perform their tasks. Furthermore, IAM
enables granular access control at the resource level, extending beyond just project-
level permissions. This fine-grained control allows for the creation of more specific
access policies based on attributes like device security status, IP address, resource
,type, and time. A comprehensive audit trail of permission authorizations, removals,
and delegations is automatically available, simplifying compliance processes. In
essence, IAM determines who (identity) has what role (access) to which resource.
Every action performed within Google Cloud necessitates specific permissions, and
IAM verifies whether the entity attempting the action possesses the required
authorization. This robust system is a cornerstone of Google Cloud security.
At the core of Google Cloud IAM are several key concepts that govern how access is
managed. Principals are the entities that require access to resources. These can
include Google Accounts representing individual users, service accounts for
applications or virtual machines, Google groups for managing access for multiple
users, Google Workspace accounts representing all accounts within an
organization's domain, Cloud Identity domains for organizations without Google
Workspace features, and special identifiers like allAuthenticatedUsers (any user
authenticated with a Google Account) and allUsers (anyone on the internet). The
variety of principal types allows IAM to manage access for a wide range of entities,
both human and non-human. The distinction between authenticated and all users
provides a mechanism to control access based on the user's identity verification
status.
Roles are collections of permissions that define the actions a principal can perform
on a resource. Google Cloud offers three main types of roles: basic, predefined, and
custom. Basic roles, also known as primitive roles (Owner, Editor, Viewer), provide
broad access to resources. Predefined roles offer more granular access control
tailored to specific Google Cloud services. Custom roles enable organizations to
define precise sets of permissions to meet their unique requirements. The
availability of these different role types allows for a balance between ease of use
and the need for fine-grained security.
Permissions dictate the specific operations that a principal is allowed to perform
on a given resource. These are typically represented in the format
service.resource.verb, providing a standardized way to define actions across Google
Cloud services. The structured format of permissions ensures clarity and
consistency in defining access rights.
Policies are the mechanisms through which permissions are granted to principals
on resources. An IAM policy is an object attached to a Google Cloud resource that
defines who has what access to that resource. Policies consist of role bindings,
which link one or more principals to a specific role for a defined resource. IAM
policies operate on a hierarchical principle, flowing from the organization node down
to folders, projects, and individual resources. This inheritance model means that
policies set at a higher level in the hierarchy are inherited by the resources below
them. Allow policies grant access, while deny policies can explicitly prevent access,
even if an allow policy grants it. Understanding this hierarchy and the interplay of
allow and deny policies is crucial for effective access management.
A Comprehensive Guide to Reviewing and Modifying IAM Roles and
Permissions
, This guide provides a step-by-step process to review and modify IAM roles and
permissions within the Google Cloud Console.
Step 1: Navigating to the IAM & Admin Section
To begin, access the Google Cloud Console. Once logged in, locate the Navigation
menu, which is often represented by three horizontal lines (the "hamburger" icon) in
the top-left corner of the console. Click on this menu to reveal a list of Google Cloud
services and administrative sections. Scroll through the menu options until you find
"IAM & Admin" and select it. This action will take you to the IAM page, which is the
central hub for managing identity and access control for your Google Cloud project.
Step 2: Locating the Target User Account
Upon arriving at the IAM page, you will see a list of principals (users, service
accounts, and groups) that have been granted roles within the current Google Cloud
project. Each entry in this list typically displays the principal's identifier (such as an
email address for a user), the role(s) assigned to them, and the source of the role
assignment. Your task is to locate the specific user account corresponding to the
student's Qwiklabs username, which is identifiable by the "@qwiklabs.net" suffix.
Carefully scroll through the list of principals until you find the entry that matches
this username. The IAM page provides a consolidated view of all entities with access
to the project and their respective roles, making it easier to manage and audit
access.
Step 3: Identifying the Current Role Assignment
Once you have located the student's Qwiklabs username in the list of principals on
the IAM page, the current role assigned to this account will be displayed in the
"Role(s)" column for that particular entry. In this specific scenario, the current role
assigned to the student account should be "Editor". The "Editor" role is a basic role
in Google Cloud that grants the principal all the permissions of the "Viewer" role,
along with the ability to perform actions that modify the state of resources, such as
creating, deleting, and changing existing resources. Understanding the scope of the
"Editor" role is important as it signifies that the student account currently has broad
capabilities within the Google Cloud project, including the ability to make changes
to the project's resources.
Step 4: Reviewing the Definitions of Basic IAM Roles
Google Cloud's basic IAM roles provide a foundational level of access control and
include three primary roles: Viewer, Editor, and Owner. It is crucial to understand
the specific permissions associated with each of these roles to effectively manage
access.
Viewer: This role grants permissions for read-only actions that do not alter
the state of resources. A principal assigned the "Viewer" role can view
existing resources and data but cannot make any modifications.
Editor: The "Editor" role encompasses all the permissions of the "Viewer"
role and additionally grants permissions for actions that modify the state of
