About the Device
Cloud NAT (network address translation) lets certain resources in Google Cloud create outbound connections to the internet or to other Virtual Private Cloud (VPC) networks, on-premises networks, or any other cloud provider networks. Cloud NAT supports address translation for established inbound response packets only. It does not allow unsolicited inbound connections.

roles/chroniclesm.admin): IAM role for performing all activities.Chronicle Service Viewer (
roles/chroniclesm.viewer): IAM role to only view the state of ingestion.Security Center Admin Editor (

To Export Filter Settings
By default, your Cloud Audit logs (admin activity and system event) and Cloud DNS logs are sent to your Chronicle account. However, you can customize the export filter to include or exclude specific types of logs. The export filter is based on the Google logging query language.

Define your filter by creating a custom filter for your logs using the logging query language.
The following documentation describes how to define this type of filter: Logging query language  | Google Cloud .Navigate to Google SecOps > EXPORT FILTER SETTINGS

When the filter/query is ready, click the edit icon and paste the filter/query in the Export filter field.
Click Save Custom Filter. Your new custom filter works against all new logs exported to your Google Security Operations account.
