How to Learn and engage in network security

I think you should first understand how to become a high-tech hacker from cainiao. You are the kind of hacker. If you are a hacker in the significance of domestic reporters (mostly synonymous with cyber criminals) it is also a real hacker (IT talents who are dedicated to improving and maintaining the system network). If it is a hacker of the former, I think you can use more tools and perform more operations. In fact, it will soon be ready, for example: many so-called hackers in China are like this. Even the OSI Layer-7 structure of the network is unclear, and they still claim to be hackers. If it is the latter, you should start from the basics, continue to learn, and, I personally think that hackers have nothing to do with fame. As long as you have a high level of technology and have contributed to the development of the network, you are qualified hackers, on the contrary, it is shameful to destroy the network by mastering hacking techniques. From the perspective of personal experience, to become a qualified hacker, you need to learn carefully. The idea is as follows:
(1) To learn English well, it is best to reach the level of university CET-4 level or above, this is to facilitate your reading of English documents and engaged in certain development work.
(2) master basic computer knowledge, such as computer software and hardware principles, operating systems, data structures, software engineering, database systems, and algorithms.
(3) familiar with the management and maintenance of common operating systems, such as Win9x/XP personal system, WinNT/2 K/2003 Server System, and Linux system, in-depth and professional study of Solaris, HP-UNIX, AIX, etc.
(4) Master network principles and management diagnostics, such as network topology, network protocols, switching and routing, and network analysis and diagnosis.
(5) several programming languages, such as compiled Asm, C, and Delphi, and script Perl, Asp, and Php.
(6) master hacker attack and defense technologies, discover system and network problems through your knowledge and skills, and solve and improve them.
The above are my personal views on hackers. I don't think we should focus on what kind of reputation it is. We should focus more on your understanding of more systems and network technologies, and can make their own contributions to society. Of course, society will also give you a good return, but you cannot pray for how much reward you will have. This depends not only on hard work, but also on opportunities, however, if you do not work hard, you will have fewer opportunities.

I think so about whether there is a future for network security. network security is always an auxiliary product of the network. From the perspective of domestic security investment accounting for about 15% of network investment, it is never the mainstream, but it is also indispensable. Engaging in network security can make you much better than the general industry, but it is almost impossible for you to pray for development like Shanda or Baidu, therefore, you must be able to withstand loneliness in the network security industry. You cannot think that if your technology is high, the reward will be huge. In fact, a friend who graduated from junior high school may earn more money by opening an online shop on the Internet, but in general, the ratio is still relatively low. Why? Because what you see is successful, there are actually more losers that you don't know about. In the end, it is a good job to engage in network security, at least better than most other occupations, however, you have to pay a lot of hardships and cannot pray for great achievements at once. If you can accept it, I'm glad you have joined the network security field.
