How to get started with network security? According to this learning route method, fools can learn!

Why learn network security:

Network security means that the hardware and software of the network system and the data in the system are protected from damage, modification, or leakage due to accidental or malicious reasons. The system operates continuously, reliably and normally, and network services are not interrupted.

As of August 2018, the number of Internet users in China has reached 802 million, and the Internet is highly developed. At the same time, the openness of the Internet and the risks brought by security breaches are everywhere. Cyber attacks are becoming more and more complex; hacker attacks are more organized; cyber attacks on mobile phone wireless terminals are becoming more serious; news about cyber attacks and data leaks are constantly emerging, and cyber security issues have become the focus of attention of governments, enterprises, and users.

Network information security has become a national strategy

What are the requirements for 70W gap learning network security

There is a serious shortage of network security talents, with a gap of more than 700,000

demand for cyber security talents is huge, and the future will be even bigger.

In 2018, the network security talent gap in China exceeded 700,000. Only 120 of the 3,000 domestic colleges and universities opened related majors, cultivating 10,000 to 20,000 people each year. With 10-20 social organizations, the country’s annual transfer of related talents was about 30,000. , The gap from the 700,000 gap is 95%. In addition, the demand for cyber security talents will increase linearly in 2020, and it is expected to reach 1.4 million, and the demand for talents will soar by 232%...

Cybersecurity salary is high and the threshold is low

Data is collected from the real salaries of thousands of practitioners in the past year. 77% believe that the salaries above are low. In addition, due to the proportion of talent transfer and talent gap in the industry, cyber security has low requirements for practitioners’ experience, and most of them are There is no limit to academic qualifications...

starting salary is high, experience is proportional to salary, the older the higher the worth

More and more industry practitioners will be difficult to make progress when they rise to a certain stage, and it is easy to be replaced by newcomers. However, network security is different from the replaceability of other industries. Network security engineers will be in short supply in the next few decades, and For defending against hacker attacks, except for a very small number of people relying on talent, experience is the first rule to ensure network security...

Network security engineers have wide employment channels and flexible directions

At present, the Internet, communications, new energy, real estate, financial securities, electronic technology and other industries urgently need network security talents. Because of the importance of network security, each industry has a different demand direction at the same time. Practitioners can completely according to their own preferences. Self-employment...
