Monitoring Network Health

•LAN Source Address on LAN

An outside device can send a forged source address in an incoming IP packet to block trace back.

•Invalid IP Packet Fragment

An outside device can send fragmented data packets that can bring down your system. IP packets can be fairly large in size. If a link between two hosts transporting a packet can only handle smaller packets, the large packet may be split (or fragmented) into smaller ones. When the packet fragments get to the destination host, they must be reassembled into the original large packet like pieces of a puzzle. A specially crafted invalid fragment can cause the host to crash

•TCP NULL

An outside device can send an IP packet with the protocol field set to TCP but with an all null TCP header and data section. If your Router responds to this attack, it will bring down your system.

•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 Router 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.
