This document describes audit logging for Service Account Credentials. Google Cloud services
generate audit logs that record administrative and access activities within your Google Cloud resources.
For more information about Cloud Audit Logs, see the following:
Each IAM permission has atypeproperty, whose value is an enum
that can be one of four values:ADMIN_READ,ADMIN_WRITE,DATA_READ, orDATA_WRITE. When you call a method,
Service Account Credentials generates an audit log whose category is dependent on thetypeproperty of the permission required to perform the method.
Methods that require an IAM permission with thetypeproperty value
ofDATA_READ,DATA_WRITE, orADMIN_READgenerateData Accessaudit logs.
Methods that require an IAM permission with thetypeproperty value
ofADMIN_WRITEgenerateAdmin Activityaudit logs.
For information about how and which permissions are evaluated for each method,
see the Identity and Access Management documentation for Service Account Credentials.
