On the one hand, the core components of the network infrastructure have never changed in the past ten years, which makes some discovered and exploited vulnerabilities and some mature attack tools have a long life cycle and are still valid even today. On the other hand, the rapid development of the application of the Internet seven-layer model has diversified the attack targets of DDoS. From the web to DNS, from the three-layer network to the seven-layer application, from the protocol stack to the application App, the endless new products have also given hackers more opportunities and breakthrough points. Moreover, DDoS protection is a project with unequal technology and cost. Often, the construction cost of a business's DDoS defense system is larger than the cost or benefit of the business itself, which makes many start-up companies or small Internet companies unwilling to make more investment.First of all, let team a and team b play one match first.

As a result, he went to Balcony, a junior public club run like a nightclub, to make money. Under the leadership of Joey's mother (Chen Jieling), he accompanied the host with Feifei (Tongan) and Sabrina (Zhong Zhuofei) every night. Securities analyst Steve N (played by Li Renshen) was brought to Balcony by rich second-generation Lucas (played by Mai Zile) in the task relationship, and saw bankers Lunye (played by Li Kaixian) and Ajie (played by Chen Yongqian). Stephen met Milo on the first day of the mission in Balcony for the first time and carried out each other. Qiao Ying, who passed the brokerage examination, hoped to allow Chen Jie to open an account, while Lucas felt for Joey's mother without being frustrated, while Lunye had a favorable opinion of Feifei. However, under the stock market, there is a hidden surge, affecting the fate of all. Looking at this piece, one can feel that Hong Kong's economic environment is too poor, just as taxi drivers sighed with emotion shortly after the opening. In such a high-end private club, there are not only a handful of girls coming and going, but also two or three girls who are a little pretty (after makeup). Their monthly income is tens of thousands of Hong Kong dollars, and they have to give it to their mommy and buy high-end cosmetics.
