Auto DoS attack prevention

• 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:
  • Scan SYNFIN — SYN and FIN bits are set in the packetÂ
  • Xmascan — TCP sequence number is zero and the FIN, URG and PSH bits are set
  • NULL scan — TCP sequence number is zero and all control bits are zeros
  • 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.
