Remediating Security Health Analytics findings

This page provides a list of reference guides and techniques for remediating Security Health Analytics findings using Security Command Center.

You need adequate Identity and Access Management (IAM) roles to view or edit findings, and to access or modify Google Cloud resources. If you encounter permissions errors when accessing Security Command Center in the Google Cloud console, ask your administrator for assistance and, to learn about roles, see Access control. To resolve resource errors, read documentation for affected products.

Security Health Analytics remediation

This section includes remediation instructions for all Security Health Analytics findings.

For finding types that are mapped to CIS Benchmarks, the remediation guidance comes from Center for Internet Security (CIS), unless otherwise stated. For more information, see Detectors and compliance.

Automatic deactivation of findings

After you remediate a vulnerability or misconfiguration finding, Security Health Analytics automatically sets the state of the finding to INACTIVE the next time it scans for the finding. Disabling a detector in Security Health Analytics also sets the state of any findings generated by that detector to INACTIVE. How long Security Health Analytics takes to set a remediated finding to INACTIVE depends on when the finding is fixed and the schedule of the scan that detects the finding.

Security Health Analytics also sets the state of a finding to INACTIVE when a scan detects that the resource that is affected by the finding is deleted. If you want to remove a finding for a deleted resource from your display while you are waiting for Security Health Analytics to detect that the resource is deleted, you can mute the finding. To mute a finding, see Mute findings in Security Command Center.

Do not use mute to hide remediated findings for existing resources. If the issue recurs and Security Health Analytics restores the ACTIVE state of the finding, you might not see the reactivated finding, because muted findings are excluded from any finding query that specifies NOT mute="MUTED", such as the default finding query.

For information about scan intervals, see Security Health Analytics scan types.
