Preschool speech
- 1. This is a road that needs to be persisted. If you only have three minutes of enthusiasm, you can give up and read on.
- 2. Practice more and think more, don't know anything without leaving the tutorial, it is best to complete the technical development independently after reading the tutorial.
- 3. If you have any questions, you can google, baidu... We often don't meet good-hearted masters, who will give you answers every day when they are bored.
- 4. If you really don't understand something, you can let it go first and solve it later.

What is Internet Security?
First of all, what is network security ? What exactly does a network security engineer do?
Network security is to ensure that the hardware and software of the network system and the data in the system are protected from being damaged, changed, or leaked due to accidental or malicious reasons, that the system runs continuously, reliably and normally, and that network services are not interrupted.
Network security work can now be subdivided into many positions, including system security engineer, network security engineer, web security engineer, security architect, etc., which will be divided according to the company's business needs.
What skills do you need to be a qualified network security engineer?
1. Network security technology
Including port, service vulnerability scanning, program vulnerability analysis and detection, rights management, intrusion and attack analysis and tracking, website penetration, virus and Trojan horse prevention, etc.
2. Have an in-depth understanding of computer systems and master commonly used programming languages
For example, windows and linux systems commonly used by enterprises, programming languages such as: Java, php, python, c, c++. Theoretically speaking, more programming languages are better. If you lack energy, you must at least know how to use them frequently.
3. Understand mainstream network security products
Such as firewalls, intrusion detection systems, scanners, etc.
4. Security protocol
Much of the content in this part is interlinked with web security. Familiar with sql injection principle and manual detection, familiar with memory buffer overflow principle and preventive measures, familiar with information storage and transmission security, familiar with data packet structure, familiar with ddos attack types and principles have certain experience in ddos attack and defense, familiar with iis security settings, familiar with ipsec , Group Policy and other system security settings.
5. Machine Learning Algorithms
Machine learning is a science of artificial intelligence. The main research object of this field is artificial intelligence, especially how to improve the performance of specific algorithms in experience learning, involving probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory and many other disciplines.
6. Artificial intelligence
Artificial intelligence is a discipline that studies the use of computers to simulate certain thinking processes and intelligent behaviors of humans. It mainly includes the principles of computer intelligence, manufacturing computers similar to human brain intelligence, and enabling computers to achieve higher-level applications. AI will involve disciplines such as computer science, psychology, philosophy, and linguistics. It can be said that almost all disciplines of natural science and social science have gone far beyond the scope of computer science. The relationship between artificial intelligence and thinking science is the relationship between practice and theory. Artificial intelligence is at the level of technical application of thinking science. is an application branch of it.
7. Big data analysis
Big data analysis refers to the analysis of huge data. Big data can be summarized as 4 Vs, large data volume (Volume), fast speed (Velocity), multiple types (Variety), and value (Value). Big data is the hottest vocabulary in the IT industry nowadays, and the subsequent use of data warehouse, data security, data analysis, data mining, etc. around the commercial value of big data has gradually become the focus of profit that people in the industry are vying for.
8. Reverse compilation
Assembly language is the starting point and end point of all programs. After all, all high-level languages are based on assembly. In many high-level languages we need relatively clear syntax, but in assembly, we use some abbreviations and numbers to express programs. To sum it up in one sentence, those of us who engage in network security are simply all-round talents. It is a bit exaggerated to say that we can use pens to secure the world, and martial arts can determine the world.
How to become an excellent network security engineer?
Here you can refer to the following growth roadmap:
and the content and goals that need to be learned at each stage:
Thank you to everyone who reads my article carefully. Reciprocity is always necessary, although it is not a very valuable thing, if you can use it can be taken directly:
① More than 2,000 e-books of network security series (mainstream and classic books should be available)
② SRC data & HW net protection action data (competition golden finger)
③ Project source code & installation package (forty or fifty interesting and classic hand-practice projects and source code)
④ Basic introduction to network security, Linux, web security, and videos on attack and defense (suitable for beginners)
⑤ Network Security Learning Roadmap (Farewell to Influential Learning)

Epilogue
To be honest, there is no threshold for obtaining the information package mentioned above.
However, I think many people get it but don't learn it.
Most people's problem seems to be "how to act" , but it is actually "can't start" .
This is the case in almost any field. The so-called "everything is difficult at the beginning" , the vast majority of people are stuck at the first step, and they have eliminated themselves before they even started.
If you really believe you like cybersecurity/hacking, do it now, more than anything else .
The field of network security is like a towering tree full of fruit. There are countless onlookers standing under it. They all claim that they like network security and want to pick the fruit from the tree, but they are hesitant when faced with the vine branches that hang down from time to time. indecision.
In fact, you can climb this tree by just grabbing any vine branch.
What most people lack is such a beginning.
