Cloud Firewall Alerts

Firewall alerts are logged if traffic is blocked by the explicit firewall rule. Alerts display in the list page. Admins must review and acknowledge the event and take additional action as needed.

To view Network events, go to SkopeIT > Events .

The page components are similar to the Network Events. However, the main difference is the acknowledge.png button.

To remove an alert from this page, enable the check boxes beside one or more alerts, click Acknowledge, and then choose Selected Alerts or All Alerts. Acknowledging the alerts will remove them from this list.
