🛡️ Google GCE Firewall Rule logging is disabled🟢

Logic​

Description​

Open File

Description​

This policy identifies Google GCE Firewall Rules that do not have logging enabled. Enabling firewall rule logging allows you to audit, verify, and analyze the effects of your firewall rules within Google Cloud VPC networks.

Rationale​

Firewall rule logging provides visibility into the network traffic that is allowed or denied by your firewall rules. Capturing these logs is critical for security auditing, monitoring unauthorized access attempts, and troubleshooting connectivity issues. Without logging, it becomes difficult to perform forensic analysis during security incidents or to validate that firewall rules are functioning as intended.

Impact​

Enabling logging may result in additional costs for log storage and processing within Cloud Logging.

Audit​

This policy flags a Google GCE Firewall Rule as INCOMPLIANT if its Log State is set to Disabled.

Remediation​

Enable Firewall Rule Logging​

Enabling logging on firewall rules allows you to capture traffic information for auditing, monitoring, and troubleshooting purposes.

From gcloud CLI​
```sh
gcloud compute firewall-rules update {{firewall-rule-name}} \
    --enable-logging
```
Consideration​

After enabling logging, traffic matching this rule will be captured in Cloud Logging, which may incur additional costs.
