Alarm Notification

After alarm notification is enabled, CFW will send notifications to you through the method you specified (such as email or SMS) so that you can monitor the firewall status and quickly detect exceptions.

CFW supports the following alarms:
  • Attack alarm: An alarm is triggered when the IPS detects an attack.
  • High traffic warning: An alarm is triggered if the traffic reaches the specified percentage of the traffic processing capability you purchased.
  • EIP not protected: An alarm is triggered when the current account has EIPs that are not protected.
  • Abnormal external connection alarm: An alarm is triggered when risky external IP addresses or domain names are detected.
