Attack Alarm
SG-1000 has two alarm forms: Internal Alarm, and External Alarm.
Internal Alarm: When the SG-1000 had detected the internal PC sending large DDoS
attacks and then the Internal Alarm will start on blocking these packets to maintain the
whole network.
External Alarm: When SG-1000 detects attacks from hackers, it writes attacking data
in the External Alarm file and sends an e-mail alert to the Administrator to take
emergency steps.
How to use Attack Alarm
The Administrator can be notified the unusal affair in Intranet from Attack Alarms. And
the Administrator can backup the Internal Alarm, and External Alarm and then delete
the records to maintain the network status.
