Auto DoS attack prevention
Auto DoS module explicitly matches attack patterns in switches and prevent network
outrage
Types of DoS Attacks can be prevented

    * Land Attacks — These attacks result from sending a specially crafted packet to a machine where the source host IP address is the same as the destination host IP address. The system attempts to reply to itself, resulting in system lockup.
    * Blat Attack — These switch result from sending a specially crafted packet to a machine where the source host port is the same as the destination host port. The system attempts to reply to itself, resulting in system lockup.
    * SYNFIN Scans — SYNchronization (SYN, ACKnowledgement (ACK) and FINish (FIN) packets are used to initiate, acknowledge and conclude TCP/IP communication sessions. The following scans exploit weakness in the TCP/IP specification and try to illicit a response from a host to identify ports for an attack:
          o Scan SYNFIN — SYN and FIN bits are set in the packet
          o Xmascan — TCP sequence number is zero and the FIN, URG and PSH bits are set
          o NULL scan — TCP sequence number is zero and all control bits are zeros
          o SYN with port ‹1024 — SYN packets with source port less than 1024.
    * Smurf Attacks — This attack uses Internet Control Message Protocol (ICMP) echo requests packets (pings) to cause network congestion or outrages.
    * Ping Flooding — This attack floods the target network with ICMP packets.
    * SYN/SYN-ACK Flooding — This attack floods the target network with SYN or SYN/ACK packets.
