Centos7, The service is no longer started using init-style scripts, Instead, the unit file is used, Therefore, commands like service iptables start can no longer be used in centos7, Therefore, service iptables save cannot be executed. At the same time, firewall is used to replace the original iptables service in centos7, but don't worry, we just need to install iptables and iptables-services through yum source (iptables are usually installed by default, but iptables-services are not installed by default in centos7). After installing iptables-services in centos7, the rules can be saved by the service iptables save command, as in centos6, and the rules are also saved in the/etc/sysconfig/iptables file.

SYN attack is a kind of DOS attack. It takes advantage of TCP protocol defects and consumes CPU and memory resources by sending a large number of semi-connection requests. SYN attacks can not only affect hosts, but also harm network systems such as routers and firewalls. In fact, SYN attacks can be implemented as long as these systems turn on TCP services no matter what systems are targeted. As can be seen from the above figure, the server receives the connection request (syn=j), adds this information to the unconnected queue, and sends the request packet to the client (syn=k, ack=j+1), then enters the SYN_RECV state. When the server does not receive an acknowledgement packet from the client, it retransmits the request packet and does not delete this entry from the non-connection queue until the timeout. With IP spoofing, SYN attacks can achieve good results, Typically, clients forge a large number of non-existent IP addresses in a short period of time, SYN packets are continuously sent to the server, and the server replies to the confirmation packets and waits for the confirmation of the customer. Since the source address does not exist, the server needs to continuously resend until it timeout. These forged SYN packets will occupy the unconnected queue for a long time, normal SYN requests will be discarded, the target system will run slowly, and in serious cases, the network will be blocked or even the system will be paralyzed.
