Another end-host-based solution is to shorten the time between a TCB entering the SYN-RECEIVED state and being recycled because it does not enter the next state. However, an obvious disadvantage of this scheme is that the attack can take advantage of ACK-SYN lost packets due to congestion or ACK packets completed by handshake, so that legally connected TCB will be recycled because the host is busy retransmitting these packets (because SYN-RECEIVED time is reduced). In addition, there is only a linear relationship between how much time the administrator reduces the SYN-RECEIVED state and the attacker's contract awarding rate. For the above reasons, this scheme is not recommended.For chronic diseases, death caused by aging is a long or short process and the last journey of life.Don't rely solely on internal defense mechanismsOK, you may have succeeded a lot here, but you will find that you can't go on, because he will let you choose an installed file to proceed to the next step.
