Types of DoS Attacks

The main types of DoS attacks are as follows:

Ø  Ping of death: Sending a malformed or otherwise malicious ping to a computer

Ø Teardrop: Forging fragmented packets designed to overlap each other when the receiving hosts defragment them

Ø  SYN flooding: Sending TCP connection requests to a target host faster than it can process them

Ø  LAND: Sending a data packet to a targeted machine with the same host and port names for the source and the destination

Ø  Smurf: Using spoofed IP addresses to send broadcast ping messages to a large number of hosts in a network to flood the system

Ø  Fraggle: Using UDP packets to flood a network

Ø  Snork: Targeted against Windows NT RPC services

Ø  OOB attack: Exploiting a bug in Microsoft’s implementation of its IP stack

Ø  Buffer overflow attack: Sending more information to a program than it is allocated to handle

Ø  Nuke attack: Repeatedly sending fragmented or invalid ICMP packets to the target computer

Ø  Reflected attack: Sending false requests to a large number of computers, which respond to those requests.
