Whether you are a college student or an unemployed person, when you want to learn network security, you will face two choices, self-study or enroll in a class. Self-study and don't know how to start, worrying that I won't be able to persist; the time for class registration is limited, and it is too expensive. what to do?
Let's first analyze the advantages of self-study and training courses.
Let's talk about self-study first
advantage:
① You will develop a good habit of self-analysis and problem-solving, which is a necessary factor for development.
②The learning time and rhythm are relatively flexible, and you can arrange it yourself according to your own situation.
③Learning cost is small, zero investment.
shortcoming:
① The skills learned are not systematic and comprehensive, and may not reach the level of employment.
②The learning cycle will be prolonged, and there may be many detours.
③The company's current recruitment requirements not only require technical level, but also require certain project experience, and the self-study project experience is lacking.
④Learning has no direction, and the problems encountered cannot be solved in a timely manner. The answers found on the Internet may not be accurate and professional. Sometimes a problem cannot be solved for several days. After a long time, the accumulation of problems will cause you to lose interest in learning. Self-doubt arises, and it will be easy to give up slowly. This is a question of learning efficiency.
Self-study is still the most chosen way. Most people try to study by themselves first.
If you decide to learn this technology by yourself, you must first have a good study habit, arrange your study time reasonably, and try to ensure that you keep learning every day , because learning safety and getting a successful job is not achieved overnight.
The next problem to be solved is to find a set of the latest tutorials and a new learning route. Many people are still reading tutorials from five years ago or ten years ago in the process of self-study, and learned a lot of outdated technologies. wasting time.
The latest network security learning route I have compiled over the past few months:
Watch these video tutorials I share, they are definitely many times better than those you find online:
Then we talk about the training class
advantage:
① There is a systematic training system.
②Learning atmosphere, there are people who also study with you.
③Learning motivation and learning cost (explain here: because of paying high tuition fees, no matter what your own learning effect is, you will definitely follow the study. This is in stark contrast to self-study. If it is self-study, There is no price. If you don’t want to learn, or if your learning effect is not good, just stop learning, but it’s different if you join a training institution. If you spend money, you will have a lot of motivation. This is more realistic.
shortcoming:
①The learning pace is fast, the cycle is short, and the teaching is crammed.
② Teaching assistants answer questions. (Most institutions are promoting lectures by famous teachers and using this method to attract students. Some of their lecturers are indeed very powerful, but whether it is face-to-face lectures or watching live broadcasts remotely, you will not have any interaction with this lecturer during the learning process. What is the intersection, the teacher is only in charge of giving lectures, and what you encounter in your studies is to go to the teaching assistants for answers. Many of these teaching assistants studied in training institutions and could not find a job, so they stayed in the school as teaching assistants. And so People with communication problems will not get any help. He may not understand it himself, and most of the time, he asks students to go to Baidu by themselves. And the courses of those training institutions with powerful lecturers are everywhere on the Internet, and the same is true when you read them online. .)
③ Tuition is too expensive. The current training courses are basically crash training , with a short cycle and fast pace , like mass production in the workshop, and the final quality will definitely be uneven.
Everyone's learning ability is different. It is impossible for two people to learn the same technology at the same time.
The original intention of the training is still very good, to lead people to systematically learn this technology for employment, but more and more people want to switch to the Internet, and most people are still not suitable for this fast-paced learning method.
If you graduated from a major, you didn’t learn well in school, or didn’t study much, but you have been in the university for several years, and you are no stranger to programming.
But for those who have zero foundation, non-scientific classes, and people who have never been in contact with it, they will not be able to keep up with the training for a period of time. It is roughly because the knowledge here is not understood. The teacher has already talked about the next knowledge point. Long-term accumulation is vicious circle.
Personally, I still do not recommend participating in training courses. If I really want to learn the technology well, the first thing is to find a set of tutorials to learn, and to develop the habit of solving problems by myself. You can go to Baidu or add some communication groups to ask for advice. It is best for friends in this industry to take you to learn, and you can also go to the Internet to meet some bigwigs.
Someone will take you to avoid detours and save unnecessary wasted time.
Regarding network security, I have also done a lot of research myself and compiled a lot of network security resources, ranging from entry to advanced, including a complete learning roadmap for red-blue confrontation, supporting video tutorials, toolkits and techniques Documentation and more:
