Auto DoS Attack Prevention

Denial of Service (DoS) attacks try to disable a device or network so users no longer have access to network resources. Auto DoS Attack Prevention module matches attack types in switches and prevent network outage

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:
  • Scan SYNFIN SYN and FIN bits are set in the packet.
  • 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.
