The second classification principle of organisms is the lineage classification principle aiming at establishing evolutionary lineage. The classification method following this principle is called lineage classification. The representative of pedigree classification is "branch systematics". It advocates that the branches in evolution should be taken as the criteria for identifying and distinguishing classification units and the basis for determining the pedigree relationship of each classification unit. The so-called co-ancestral proximity (similar to a group of people being a grandfather) is used to measure the genetic relationship between different taxa and determine their position in the pedigree. The classification system finally established is an evolutionary pedigree reflecting the history of phylogeny, which is a deeper description of biological relationship. In other words, the basic principle of pedigree classification is that the classification system conforms to the evolutionary pedigree. Pedigree classification is only applicable to organisms and cannot be used for abiotic classification.
那是在一亿七千五百万年前，三颗陨石由外太空飞来，坠落于三个不同的地方化身成不同的人物。每二亿年，太阳黑子便会爆发产生宇宙风暴，天界众神的力量便会减弱，而代表黑暗力量的天魔亦会出现。要打败天魔，惟一方法是要某年某月某日某时某刻某分某秒出世的人，由其中一颗陨石的化身护送他到西天取《三藏真经》；该石须在取经过程中找到另外两个陨石的化身，再待天魔出现时，借真经力量，三石合一，才能战胜天魔，否则天地将会变成鸿蒙一片，返回混沌世界。

3. The third handshake: the client receives the SYN + ACK message segment from the server. Then the Acknowledge Number is set to y+1, and the ACK message segment is sent to the server. After the message segment is sent, both the client and the server enter the ESTABLISHED state, completing the TCP three-time handshake.

Recently, security researcher MathyVanhoef found that there are logical defects in WPA2 protocol layer. Almost all Wi-Fi-supporting devices (including but not limited to Android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys) are threatened, and the data transmitted by them are at risk of being sniffed and tampered with. Attackers can obtain data information in WiFi network, such as credit cards, emails, account numbers, photos, etc., which is extremely harmful.

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.
