In the face of serious involution in 2021, how should operation and maintenance engineers practice?

Foreword:

The 618 big promotion that ended some time ago, I believe everyone has spent a lot of money. Picture, in fact, behind every big promotion, the major e-commerce platforms are still suffering from black production attacks again and again. Take Alibaba last year’s double ten. For example, behind the 268.4 billion transaction volume, there were 2.2 billion black production attacks in one day.
In recent years, cyber security incidents have emerged one after another. I believe you have heard a lot of them even if you haven't encountered them. For example, servers are invaded and hacked, user accounts are stolen; phishing, ransomware, etc., once these occur, it is a big blow to the enterprise.

Therefore, network security cannot be ignored. At the same time, with the continuous development of the times, the company's requirements for operation and maintenance and network engineers are becoming more and more stringent. In the future, more and more popular talents must be compound talents with a wide range of skills.

Network security can be said to be another development path for network engineers and operation and maintenance personnel.

During the two sessions this year, Zhou Hongyi, a member of the National Committee of the Chinese People's Political Consultative Conference, the founder and chairman of 360 Group, submitted a proposal on special talents in the cyber security industry to strive for better treatment for the majority of white hats.

According to statistics, the current technical staff can only fill up less than 1% of the gap! This imbalance in supply and demand is directly reflected in the salary of security penetration engineers. Simply put, the pressure of competition is low, and the salary is still high.

It is a very important direction for many network operators to improve their choices!

Moreover, it is highly flexible. You can choose a company to engage in full-time information security research work, or you can choose a freelance job to submit vulnerabilities to some SRC or vulnerability receiving platforms and get bonuses:

So is it difficult to learn hackers without basic knowledge?

I have planned a systematic learning system from zero basis → hacker masters.

The first step for a zero-based novice should be:

An understanding of the communication principle between the front and back ends of the Web and the server. (Front-end and back-end: H5, JS, PHP, SQL, server: WinServer, Nginx, Apache, etc.)

Step 2: The principle and use of current mainstream vulnerabilities

At this time, it should be the principle and utilization of mainstream vulnerabilities such as SQL, XSS, and CSRF.

Step 3: Excavation and audit of current mainstream vulnerabilities

Learn the idea of 0day dug by the predecessors, and reproduce it, try the same audit

This three-step learning method is enough for novices to get started to small.
