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.

Those who came to watch and learn tried to run their own pictures, but they were not very successful. Alone is often planted in various rescue gates.
But in that case, Not even considering so many dangers, This performance of '74 spray' is of great use, I remember there were 4 '74 spray' on the position at that time, There are two recruits who operate them. Two veterans, Both veterans were squad leaders, All have the skills of air injection, Facing the big wasp descending from the pavement, The two of them were obviously forced to hurry, Take up the '74 spray' and aim at the position where the big wasp is relatively concentrated in the sky and spray it out. If it weren't for the critical situation at that time, the two squad leaders would definitely not have this kind of "dangerous operation", while the other two recruits watched the veterans take the lead and learned to do so. Although they had not received relevant training and the accuracy of spraying was not as good as that of veterans, they finally sprayed out and did not hurt themselves or other comrades in arms.

With the upsurge of learning various management experiences from Huawei in recent years, The BLM (Business Leadership Model, commonly known as "Don't Touch") model introduced by Huawei from IBM for 30 million yuan in 2006 has also been hotly discussed by the business and management consulting circles. However, at present, the vast majority of online information on BLM is only at the level of brief introduction. There are two kinds of BLM translations, one is the "business leadership model" and the other is the "business leadership model". The difference between the two translations reflects the difference in the specific application of this set of tools. The former regards it as a strategic planning tool, while the latter uses it to enhance the leadership of middle and senior managers. IBM's original intention in introducing BLM to Huawei was to unify the strategic thinking methods and framework of Huawei's middle and senior managers and to enhance their leadership, because managers' leadership was gradually cultivated in the process of formulating strategic plans and promoting strategic implementation. In the subsequent actual use of this tool, It was found to be an inclusive thinking framework, It can integrate various tools previously used in strategic planning, such as MM (Market Management) of IPD (Integrated Product Development), strategy decoding, strategy map, balanced scorecard, etc. into it. And can use this thinking framework and strategic language from the company strategy to the business unit strategy and then to the strategy of each functional system. Therefore, when each major product line and PDT formulate SP (Medium and Long Term Strategic Plan, Spring Plan) and BP (Annual Business Plan, Autumn Plan), each
