Firewalls

Learn how to create and manage firewalls.

When you create a firewall, you'll select a firewall policy to associate with it. If you haven't created a firewall policy yet, see Firewall Policies. The policy contains the rules that control how the firewall inspects, allows, or denies network traffic. Firewalls can share policies.

When you create a firewall, usual Network Firewall service limits and restrictions apply.

Important

The firewall denies all traffic until you configure rules in its associated firewall policy.

Monitoring firewalls

You can monitor the health, capacity, and performance of your Oracle Cloud Infrastructure resources by using metrics, alarms, and notifications. For more information, see Monitoring and Notifications.

Logging firewall activity

You can enable logging for your firewalls if the rules in the associated policy support it, and you are subscribed to the Logging service. Logs display events within a specified time frame.
