Alert Log
The device provides the following warning message. Click to activate these features: Syn Flooding,
IP Spoofing, Win Nuke, Ping of Death / Unauthorized Login Attempt.
Syn Flooding

Bulky syn packet transmission in a short time causes the overload of the
system storage of record in connection information.
IP Spoofing
：
Through the packet sniffing, hackers intercept data transmitted on the
network. After they access the information, the IP address from the sender
is changed so that they can access the resource in the source system.
Win Nuke
：
Servers are attacked or trapped by the Trojan program.
Ping of Death
：
The system fails because the sent data exceeds the maximum packet that
can be handled by the IP protocol.
Unauthorized
Login

If intruders into the device are identified, the message will be sent to the
system log.
