A SYN flood attack requests a connection and then fails to
promptly acknowledge a destination host's response, leaving the
destination host vulnerable to a flood of connection requests.
A source routing attack specifies an exact route for a packet's
travel through a network, while exploiting the use of an
intermediate host to gain access to a private host.
A "Win-nuking" attack uses the IP address of a destination host to
send junk packets to its receiving port.
An FTP bounce attack uses the PORT command in FTP mode to gain
access to arbitrary ports on machines other than the originating
client.
An IP unaligned timestamp attack uses a frame with the IP
timestamp option, where the timestamp is not aligned on a 32-bit
boundary.
A sequence number prediction attack establishes a three-way TCP
connection with a forged source address. The attacker guesses the
sequence number of the destination host response.
A MIME flood attack uses an improperly formatted MIME header
in "sendmail" to cause a buffer overflow on the destination host.
Use the Max Header Length
header length (at least 256 bytes).
Use the Max Headers
headers allowed (at least 12 headers).
