Cloud Firewall Network Events and Alerts
Cloud Firewall Network Events and Alerts
Network Events log all traffic that is steered to Netskope at the connection level.
To view Network events, go to Skope IT > Events > Network Events.
For all traffic except HTTP(s), system logs once when the session is established and logs again when the session closes. For HTTP(s) traffic, system only logs when the session closes.
The default Network Events page table includes:
- Time: The day and hour the event occurred
- Username: email address of the user that caused the alert
- Application: The application specified, if any, in the Real-Time Protection policy
- DST Port: User’s destination port
- Traffic Type: NSFW which stands for Netskope Firewall (NOTE: Traffic Type is not visible by default. Click the icon to open the Customize Columns window and add it to the table view).
- Policy Name: The name of the Real-Time Protection policy
- Action: The action specified in the Real-Time Protection policy
- Total Bytes: Total Bytes transferred using the traffic flow (Total Bytes = Bytes Uploaded by User + Bytes Downloaded from Server)

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 Skope IT > Events .
The page components are similar to the Network Events. However, the main difference is the 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.
