This document describes a threat finding type in Security Command Center. Threat findings are generated by
threat detectors when they detect
a potential threat in your cloud resources. For a full list of available threat findings, see Threat findings index.
Overview
Event Threat Detection examines audit logs to detect the deletion of hosts that are
running applications protected by the Backup and DR Service. After a host is deleted,
applications that are associated with the host cannot be backed up.
How to respond
To respond to this finding, do the following:
Step 1: Review finding details
Open the Impact: Deleted Google Cloud Backup and DR host
finding, as detailed in Reviewing findings. The details panel for the finding opens to the Summary tab.
On the Summary tab, review the information in the following sections:
What was detected, especially the following fields:
Application name: the name of a database or VM connected to Backup and DR
Host name: the name of a host connected to Backup and DR
Principal subject: a user that has successfully executed an action
Affected resource
Resource display name: the project in which the host was deleted
Related links, especially the following fields:
MITRE ATTACK method: link to the MITRE ATT&CK documentation
Logging URI: link to open the Logs Explorer
Step 2: Research attack and response methods
Contact the owner of the service account in the Principal email field.
Confirm whether the legitimate owner conducted the action.
Step 3: Implement your response
The following response plan might be appropriate for this finding, but might also impact operations.
Carefully evaluate the information you gather in your investigation to determine the best way to
resolve findings.
In the project where the action was taken, navigate to the management console.
Confirm that the deleted host is no longer in the list of Backup and DR hosts.
Select the Add Host option to re-add the deleted host.
