In GCP, IAM stands for Identity and Access Management. It is a service that allows you to control who has access to your GCP resources and what actions they can perform on those resources. IAM enables you to create and manage users and service accounts, and assign roles to them that determine their level of access.
IAM roles include predefined roles such as “Editor,” “Viewer,” and “Owner,” as well as custom roles that you can create to fit the specific needs of your organization. Each role includes a set of permissions that determine the actions that users and service accounts with that role can perform.
IAM also allows you to use fine-grained access control by applying conditions, such as time of day or geographic location, to further restrict access to resources.
Using IAM, you can ensure that only authorized users have access to your GCP resources and that they can only perform the actions that are necessary for their job.
