Google Cloud Platform (GCP) permissions are essential to control who can access, manage, and modify resources within your GCP account. When you’re managing resources, like virtual machines, storage, and networking, it’s important to set the correct permissions to ensure security and proper access levels.
Understanding GCP Permissions
GCP permissions work based on Identity and Access Management (IAM), which controls access to resources in your Google Cloud environment. Permissions are granted to users, groups, or service accounts through roles. These roles define what actions a user can perform on resources.
Key GCP Permission Levels
-
Owner
-
Full administrative access to all GCP resources.
-
Can view, create, and delete resources.
-
Can manage permissions for other users.
-
-
Editor
-
Similar to Owner but without the ability to manage IAM policies (permissions).
-
Can create and modify resources, but cannot assign roles or manage billing.
-
-
Viewer
-
Read-only access to resources.
-
Cannot modify, create, or delete resources, but can view them.
-
-
Custom Roles
-
Tailored roles with specific permissions. Useful for setting granular permissions.
-
You can create custom roles to control what specific users or services can do with the resources in your GCP project.
-
Managing Permissions in GCP
You can manage GCP permissions via the IAM & Admin section in the GCP Console or using gcloud CLI commands.
Setting Permissions via GCP Console:
-
Go to the IAM & Admin section of the Google Cloud Console.
-
Select IAM from the left-side menu.
-
Click Add to assign a new role to a user, group, or service account.
-
Enter the email address of the user or service account.
-
Select the role(s) you want to assign (Owner, Editor, Viewer, or Custom).
-
Click Save.
Setting Permissions via gcloud CLI:
You can assign roles using the gcloud command-line tool:
Recommended Practices:
-
Principle of Least Privilege: Always grant users the minimum required permissions for their job functions.
-
Use Custom Roles: For more precise control over permissions, especially if you want to restrict access to certain features but not others.
-
Audit Permissions Regularly: Check permissions periodically to ensure that users only have access to the resources they need.
Example Use Case – Hosting Resources
For example, if you’re managing hosting resources for a site like “hostdiscountcode.com”, you might want to set different permissions for the development and marketing teams.
-
Developers might need Editor permissions to modify server configurations, but should not have access to billing information.
-
Marketing might only need Viewer permissions to see traffic data, but should not modify any infrastructure.
Useful Links for GCP Permissions
Managing GCP permissions is a crucial step to secure your hosting infrastructure and avoid unintentional changes. By customizing IAM roles, you ensure that each user or service has only the necessary access to the resources they need.
