It mainly refers to the Top 10 security events detected by the firewall across the network within a particular time. In these security events, if the attacking threat passes through the firewall and is detected by the firewall, the corresponding attack threat will be marked in red. If the traffic flowing through the firewall contains no attacking threat, the corresponding attack threat will be marked in gray.

If you click a hot event, the logs of this event will be shown in the table. See the figure below.
