•TCP FIN
An outside device can send an attack using TCP FIN. This attack never allows a data packet to finish transmitting and brings down your system.
•TCP XMAS
An outside device can send an attack using TCP packets with all the flags set. This causes your system to slow to a halt.
•Fragmented TCP Packet
An outside device can send an attack using fragmented packets to allow an outside user Telnet access to a device on your network.
•Fragmented TCP Header
An outside device can send an attack using TCP packets with only a header and no payload. When numerous packets are sent through the Gateway in this manner, your system slows and halts.
•Fragmented UDP Header
An outside device can send an attack using fragmented UDP headers to bring down a device on your network.
•Fragmented ICMP Header
An outside device can send an attack using fragmented ICMP headers to bring down a device on your network.
•Inconsistent UDP/IP header lengths
An outside device can send an attack using inconsistent UDP/IP headers to bring down a device on your network.
•Inconsistent IP header lengths
An outside device can send an attack using changes in the IP header to zero the fragment offset field. This will be treated as a complete packet when received and cause your system to halt.
