The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.孤儿石惠被孙大凯寡母收养，为报答孙母养育之恩，石惠与孙大凯结合。石惠发现孙大凯嗜赌，在与孙大凯离婚后又被孙大凯强奸，孙大凯因此入狱，此后，石惠接受了崔文军的求爱。面对崔母的挑剔和事业的坎坷，石惠顽强拼搏，并生下女儿瑶瑶。崔母意外发现瑶瑶原是孙大凯的女儿，要求崔文军立刻离婚。石惠带瑶瑶离开了石惠艰难创业，服装生意蒸蒸日上，崔母重病，石惠在身旁精心照顾。崔母深受感动，反过来撮合石惠和崔文军复婚。瑶瑶得了重病必须换肝，符合条件的崔文军逃走，石惠被迫找到孙大凯。换肝手术成功，但瑶瑶失明了。一直暗恋石惠的大款潘国庆破产后自杀，石惠将他救下来，却因经济纠纷被调查，孙大凯出面证实，其实是林芳所为，石惠被洗脱嫌疑。石惠的大爱与宽容感动了所有人，潘国庆也在石惠的劝说下去寻找一直深爱他的林芳。Apart from the family stories that make people feel kind, many characters in "Suspicious Three Brothers" have lovely shortcomings.
