The majority of DDoS attacks focus on targeting the transport and network layers. These types of attacks are usually comprised of volumetric attacks that aim to overwhelm the target machine, denying or consuming resources until the server goes offline. In these types of DDoS attacks, malicious traffic (TCP / UDP) is used to flood the victim. Taking it one step further, these attacks also drive to saturate the entire network with malicious traffic until it is rendered temporarily obsolete. While these types of attacks can be a disruptive force for businesses, once the attack ceases or has been mitigated, there is no lasting damage.
