Overview
The default Firewall rules will apply to all instances by default in the absence of specific custom rules with higher priority. It is a safe practice to not have these rules in the default Firewall.
Remediation guidance
- Login to GCP Console and from Networking, select VPC network.
- Click on the name of the default network and go to Firewall Rules
- Select all rules starting with default- excepting http and https and delete them
Service-wide remediation
Recommended when many resources are affected: fix the platform baseline first so new resources inherit the secure setting, then remediate the existing flagged resources in batches.
Google Cloud
Use organization or folder policies where available, shared project templates, logs and alerting baselines, and IaC modules so new resources inherit the secure setting.
Operational rollout
- Fix the baseline first at the account, subscription, project, cluster, or tenant scope that owns this control.
- Remediate the currently affected resources in batches, starting with internet-exposed and production assets.
- Re-scan and track approved exceptions with an owner and expiry date.
Query logic
These are the stored checks tied to this control.
The default firewall does not have any default rules besides http and https
