If a service needs to be public-oriented, it needs to provide a user access interface. These interfaces just give hackers the opportunity to take advantage of them. For example, the TCP/IP protocol handshake defect can be used to consume the link resources of the server, The stateless mechanism of UDP protocol can be used to forge a large number of UDP data packets to block communication channels... It can be said that the world of the Internet has not lacked attack points exploited by DDoS since its birth, from TCP/IP protocol mechanism to CC, DNS and NTP reflection attacks, and what's more, it uses various application vulnerabilities to launch more advanced and accurate attacks.
Model Reconstruction: The key idea here is that attackers can recreate the model by probing the public API and gradually improve their own model by using it as Oracle. A recent paper (https://www.usenix.org/system/files/conference/usenixsecurity16/sec16_paper_tramer. Pdf) shows that this attack seems to be effective for most artificial intelligence algorithms, including support vector machines, random forests and deep neural networks.

首部反映中国税务稽查人员工作、生活和情感的电视连续剧《利剑》，由美女张恒及马跃、达式常等主演。《利剑》的故事曲折，它以国税稽查系统近年来破获的典型案件为原型，描写了南江市国税局组成以复局长邝亚北为组长的专案组，对偷税骗税活动进行代号为“利剑行动”的专项打击活动……中国南部随着改革开改经济快速发展，跨国黑帮金融犯罪的手法日益昌獗，犯罪分子盗取国库财富的罪行日新月异……为了斩断黑手，稽查惩处洗钱犯罪，打击腐败分子，由南江省稽查局长常泳波为首的专案组，开始了代号为“利剑”的反洗钱行动，直逼南明市……跨国黑帮洗钱集团首脑司马凌云在南明市苦心经营多年，虚设企业二十多家，仅虚开增值税发票一项，每年就给他赢利上亿元。另外正常运营的二、三家企业开张后也一直逃税。虽然，这些企业都是雇人前台操做。但如果常泳波追查到底，每年上亿元的收益泡了汤，他着实于心不甘……专案组连续出击，都由于南明市地税局副局长孙朗的通风报信，无功而返；十张没有发放连号的增值税发票更象一个重磅炸弹出现在专案组的视线。追查票据来源，惊天大

Regular maintenance generally refers to the regular inspection and maintenance of hardware facilities. The range of detection here is as wide as possible. If the range is too large, Depending on asset type and asset range, Sampling tests are conducted, But all machines must be checked once a year, Replace the equipment with unstable performance or failure in time. Attention should be paid to monitoring the hardware equipment here. I have encountered the event of standby server failure for half a month. Let's not talk about it. Finally, maintenance should cover all equipment, regardless of network, security, server, basic power, air conditioning, UPS, etc.
1. As a math student, I have studied math for four years, and I don't agree with the bibliography you gave at random. First, there is no step type and it is unfriendly to beginners. Your title and the purpose of writing this series are probably for Xiaobai to see. So, may I ask, a Xiaobai needs to see the principle of mathematical analysis? ? Is it necessary to look at Princeton Calculus Principle to learn artificial intelligence? ? In my shallow understanding, the biggest difference between mathematical analysis and advanced mathematics is the same theorem. High numbers only require that they can be used. Mathematical analysis is rigorous and will definitely give proof. However, for the mathematics needed in most artificial intelligence, you need to prove the correctness and completeness of this theorem in your work? ? I'm afraid the project will be closed long ago when you prove it. You replied to me that this is only a bibliography, not a recommended bibliography, but most of the following comments decided to give up when they saw the book list. If you put these books out, it will be instructive to those who read your articles. I think you are misleading people. Second, I have roughly deduced from the number of references you have made that you may not have a framework for the mathematics of the whole artificial intelligence, otherwise there would not have been such irresponsible recommendations. However, out of respect for you, I did not question your ability. I only gave a brief recommendation in the comments on the suitable math bibliography for beginners.
