This document describes audit logging for Blockchain Node Engine. 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 a type property, whose value is an enum
that can be one of four values: ADMIN_READ, ADMIN_WRITE,
DATA_READ, or DATA_WRITE. When you call a method,
Blockchain Node Engine generates an audit log whose category is dependent on the
type property of the permission required to perform the method.
Methods that require an IAM permission with the type property value
of DATA_READ, DATA_WRITE, or ADMIN_READ generate
Data Access audit logs.
Methods that require an IAM permission with the type property value
of ADMIN_WRITE generate
Admin Activity audit logs.
For information about how and which permissions are evaluated for each method,
see the Identity and Access Management documentation for Blockchain Node Engine.
