Detect Ping of Death Attack:
„ Select this option to detect the attacks of tremendous trash data in PING packets

that hackers send to cause System malfunction. This attack can cause network

speed to slow down, or even make it necessary to restart the computer to get a

normal operation.

Detect IP Spoofing Attack:
„ Select this option to detect spoof attacks. Hackers disguise themselves as trusted

users of the network in Spoof attacks. They use a fake identity to try to pass

through the SG-1000 System and invade the network.

Detect Port Scan Attack:
„ Select this option to detect the port scans hackers use to continuously scan

networks on the Internet to detect computers and vulnerable ports that are opened

by those computers.

Detect Tear Drop Attack:
„ Select this option to detect tear drop attacks. These are packets that are segmented

to small packets with negative length. Some Systems treat the negative value as a

very large number, and copy enormous data into the System to cause System

damage, such as a shut down or a restart

.

Filter IP Route Option:
„ Each IP packet can carry an optional field that specifies the replying address that

can be different from the source address specified in packet’s header. Hackers can

use this address field on disguised packets to invade LAN networks and send LAN

networks’ data back to them.
