Fragmentation: by sending fragmented packets, the attacker will be under the radar and can certainly bypass the detection procedure's capability to detect the attack signature.
Handle spoofing/proxying: attackers can improve The issue of the Security Directors ability to find get more info out the supply of the attack through the use of poorly secured or incorrectly configured proxy servers to bounce an assault.
