fan question
I am now a freshman student in Huake, majoring in electrical related. But after thinking about it myself, I want to choose the direction of cyberspace security. Because I heard on the Internet that there is still a lot of room for development in cyberspace security in China. I am also interested in this direction, and I also plan to study in depth (maybe I will go to graduate school or do a Ph.D.), and my family is also more supportive. I. Recently, I spent money to buy related training courses, so I have already set sail. So I would like to ask in this direction:
- ①I want to know how the industry views cyberspace security.
- ②Do you have any supplementary comments and suggestions?
reply
First of all, congratulations, you have chosen a very potential professional field, and it is a major that requires talent and education. You are from Huake, and your undergraduate degree is very strong. If you can take the postgraduate entrance examination and do a Ph. "ah!
The salary cap in this direction is very impressive and terrible, just outrageous!
When I was in college, anti-virus software was required for every computer, so Kingsoft Antivirus and 360 were very powerful at that time, but later, basically everyone chose bare metal. Bare metal, so network security has shifted from the civilian level to a higher level over the years. So there are fewer job openings than before.
But at the same time, the requirements for this position have also increased, and the salary is higher than before. Just search on the recruitment website, for example, the network security engineer recruited by Huawei, with 1-3 years of work experience, can give 30-50k, good smell.
If network security is raised to the national level, then the salary will be outrageous.
With the upgrading of industries and the popularization of informatization and digitalization, if everything is really connected, then the requirements for network security at the national level will become higher and higher. Therefore, I think your future is limitless, provided that you must learn well by yourself , Xuetong, Xuejing, I am looking forward to your performance in the future.
I personally think that cyberspace security includes network security and information security. Network security is relatively traditional, macroscopic, and physically visible security, such as waf, nf, ids/ips, bastion host, etc. The tools for working at the lower layer of the TCP/IP model; information security is in terms of network security and computers, such as programming The language, operating system, cms, and java middleware framework are developed on the basis of the middleware framework, and the range considered by the application layer in the TCP/IP model. Of course, I think the difference between hardware and software is not bad.
second question.
As for how to learn cyberspace security, I think, first of all, you must have great enthusiasm, that is, you like to play things in this area, and secondly, there are few learning materials in this area, unlike Java. Very systematic, I myself am a layman in terms of cyberspace security.
Since you want to decide to take this path, you must have a solid foundation in computer science, and learn operating systems, computer networks, data structures, and algorithms. I also plan to share my experience and give some advice and learning methods to those who want to find a job or change careers!
1. Clear learning objectives
The most important thing is to understand what the purpose of learning cyber security is, whether it is to discover vulnerabilities or to infiltrate, whether it is an interest in learning or a job, whether it is to become a powerful hacker or a cyber security practitioner. Only when you understand the purpose can you have the motivation to continue learning. My goal at the time was very clear, which was to find a high-paying job in order to change careers.
2. Make a study plan.
In the early stage of learning, it is necessary to formulate a detailed learning plan, and formulate corresponding learning goals according to the content of the plan, which can be refined to the goals of each day, and then carry out daily learning summary and plan learning.
To make a study plan, you must first choose a good direction. The scope of application of network security is very wide. After learning the basic knowledge of network, if the application direction is different, the things to learn will be very different. I can’t say that I want to do penetration development, learn the basic knowledge of the network, go to learn kali, penetration testing and other knowledge; I can’t say that I want to do vulnerability analysis, learn the basic knowledge of the network, and then go to learn how to dig holes and play games .
Therefore, if you want to learn cybersecurity well, it is very important to choose a good direction, and most novices do not know the direction of cybersecurity, and may not understand some analysis. My suggestion is to find someone who understands and has experience to guide you. If it is said that these people are the best among the friends you make, don’t worry if you don’t have any. Just go to the corresponding network security exchange group. Baidu can find some information to learn from.
The following points are very important in the learning process:
1) Make good notes, the same problem will be encountered a second time, and it is easy to review with a note;
2) Make good use of Baidu and forums, the problems you encounter now, most of the predecessors have encountered;
3) Keep reading when you are confused, because you are a novice after all, and you don’t understand too much, you have to understand him;
3. Select the learning materials.
Today, with the development of the Internet, as long as you want to learn, you will never find information on the Internet, which leads to piles of materials recommended by various great gods. Take a look here, glance there, and the knowledge is messy and disorderly. complete system. Therefore, the selection of data is very important. I don't recommend buying books, because the quality of books in China is uneven, and reading and learning is more painful. I personally have a deep understanding. Just need to read some worthwhile e-books
I also sorted out the documents I got and my learning logical thinking, and shared them with everyone. Friends in need can pick them up. Note that this is suitable for Xiaobai to learn from 0 to 1. If you have a certain Basic needs to be advanced can be ignored.
4. Choose the right learning method.
The right learning method can help you avoid many detours. This is very important, because if you choose an inefficient learning method, maybe others have already learned it thoroughly
For Xiaobai, it is much more efficient to be guided by someone than self-study, especially for friends who are easy to persevere. With a big cow leading the entry, you can avoid a lot of detours!
5. Practice more and watch more
Any IT learning is based on practice. Without practice, it is like spending half a day learning the theory of shooting a gun, but in the end there is no chance to touch the gun. Do you think you can shoot accurately? If you want to learn cyber security well, you must practice more. Without the bonus of proficiency, no matter how much you learn, it is only on paper. Once you face real problems, you will have no way to start.
You have to read more, and you have to be good at reading and learning other people's excellent cases, so that you can gradually realize the true essence of Internet security.
It is not difficult to learn cyber security, but the hard part is to persist and believe in yourself. My experience is that since you have chosen cyber security, you have to believe in it, and believe that it can become an efficient channel for you to advance in the future, so that you will be more confident. Only by learning with faith can we persevere when encountering difficulties.
Opportunities belong to those who are prepared. This is an era of strength. The gap between people does not lie in IQ, but in how to use spare time. As long as you want to learn, it is never too late to start. Don’t worry about this or that. You just need to work hard and leave the rest to time!
