Today, distributed attacks are really feasible because criminals have thousands of hosts for him to carry out denial of service (DoS) attacks. Since these large numbers of hosts can continuously increase or decrease and can change their IP addresses and their connections, it is still a challenge to prevent such attacks.
Reflective attacks typically use protocols that do not require authentication or handshake, The reflection attack needs to forge the source ip address of the requested data into the ip address of the target. If the protocol used requires authentication or handshake, the authentication or handshake process cannot be completed and the next attack cannot be carried out. Therefore, most reflection attacks are carried out by network services based on udp protocol.
