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.

女一号韩雪这次的出镜绝对称得上是“形象大颠覆”，她饰演的女记者林曼怡，是个做事执着、个性乐观善良，但却常常要犯“迷糊”，甚至有点“二”的角色。韩雪说：“林曼怡是个换了38份工作的‘打工女皇’，但她永远有信心，作为记者，她有一个信念就是‘我要还原事实，我不要掩饰、粉饰’”。“林曼怡的傻是不谙世故，但也正是这一点，让她具备很难得的真诚和率真一面。这种东西在剧中感染了很多人，包括男主角，相信也会感染观众的。”
JIT theory holds that the most precious wealth of an enterprise is not the machine building or the product, but the employees in the production line. Employees are the source of wisdom for enterprise development. Only when front-line employees meet the requirements in their operations can the system truly realize its functions. Only when each employee exerts his creative ability can the whole system acquire real dynamic adaptability and self-improvement ability. If employees do not understand JIT production, do not actively participate in production activities, do not play their own independent spirit, and do not participate in enterprise improvement activities, the problems in production will not be exposed and solved. The secret of the success of JIT production mode lies in "full participation". One of its important characteristics is endless improvement. To this end, enterprises have invested a lot of energy in various aspects of training to improve the quality of employees. Teamwork, multi-ability in one post and multi-machine in one person have all become necessary skills for frontline employees. JIT production mode realizes the overall flexibility of the system through the operation of the organization and the high ability of employees.
