How about the network security major?

IT industry is a sunrise industry at present, and network security is an important module. From a policy perspective, the implementation of the Network Security Law and the establishment of the Network Information Office mean that security has been paid more and more attention. From the perspective of the whole industry, the shortage of safety talents is becoming more and more serious.

Enterprises pay more and more attention to information security or network security, and invest higher budget. According to a survey conducted by Gartner, although 95% of CIOs expect that cyber threats will increase in the next three years, only 65% of organizations actually have their own cyber security experts. The survey also found that skills challenges continue to plague organizations that implement digitalization. The shortage of digital security personnel is considered as the biggest obstacle to innovation.

Gartner's 20 18 CIO agenda survey collected data from 3 160 CIOs from major industries in 98 countries. The revenue/public sector budget of these CIOs is about 13 trillion US dollars, and the IT expenditure is 277 billion US dollars.

McMillan said: "In other words, many cyber criminals are pioneers of digitalization. They try their best to use big data and network-level technology to launch attacks and steal data. CIOs can't protect their organizations from all kinds of violations, so they need to create a set of sustainable controls to balance their needs to protect their business and operate their business. "

35% of the respondents indicated that their organizations have invested in and deployed some digital security measures, while another 36% of the respondents are actively trying or planning to implement these measures in the short term. Gartner predicts that by 2020, 60% of the security budget will be used to support detection and response functions.

Maybe your day starts like this: turn off the alarm clock on your mobile phone, then quickly browse the information you received last night, check the weather application to see if you need to take an umbrella before going out, and use GPS to see which way to take when driving to work is easy ... In fact, most people surf the Internet first thing in the morning.

More and more applications carry bits and pieces of life, but it also makes people face new risks. Many companies realize that if security measures are not in place, they will face a lot of losses: a recent survey of companies by the World Economic Forum in Davos shows that network security has become the most concerned issue of American CEO.

So, who will protect the company's network security? The answer is network security experts. In order to better understand the demand, salary level and interest of job seekers, this paper analyzes the global data of cyber security positions from 20 17 to 20 18 on the Indeed recruitment website to tell you which talents employers like best and which jobs are real "golden rice bowls"!

The demand for network security professionals is increasing. As far as American listed companies are concerned, from 20 16 to 20 17, the growth of network security jobs is not obvious (0.28%), but from 20 17 to 20 18, the demand has increased by 7%. In 20 18, the company that posted the most related positions was Catapult Consultant, whose business focused on business analysis and information systems, followed by the banking giant Wells Fargo.

The reasons for the surge in job demand in 20 18 are the global large-scale cyber security incidents in 20 17, such as the network interruption of Ukrainian power companies, airports and central banks, the suspension of the service of the British national medical service system, and the publication of nearly 9,000 stolen CIA documents on the Wikileaks website.

The data of network security in other countries except the United States changed greatly from 20 17 to 20 18. For example, in 20 18, the number of jobs released in India increased by 39% compared with 20 17. In 20 18, the demand for network securITy in India was mainly concentrated in Wipro, whose main business was consulting, service and it.

The number of cyber security jobs in Ireland has also increased significantly by 18%. Ireland attracted more than 65,438+0,000 multinational companies to open offices here with its low tax rate and relaxed business supervision environment, including Facebook, Apple and Amazon, among which Amazon was the company that posted the most related jobs in Ireland in 2065,438+08.

In order to evaluate the interest of potential job seekers, we analyzed the cyber security positions with the highest click rate on the Indeed recruitment website, and found that the high enthusiasm of American employers is not consistent with the interest of employees. From 20 17 to 20 18, the click rate of related posts of American listed companies decreased by 1.3%.

The network security industry is not attractive to employees from women and millennials. WesleySimpson of the International Information System Security Certification Association believes that the reason is insufficient publicity of this industry.

Other problems lie in the recruitment information itself. Simpson said that the language used in network security recruitment information is vague, the job description is similar, and programming experience or bachelor's degree is required-he believes that employees can cultivate most necessary skills at work, so experience and degree are not necessary. When recruiting, the information release should be concise and to the point, and indicate whether the corresponding training will be provided.

On the other hand, job seekers from other countries are more interested. For example, compared with last year's data, the click rate of posts in Israel increased by18% in 20 18 years; Dutch growth13%; Australia increased 1 1%.

The figure shows the number of job postings in 20 17 and 20 18, and the changes of job seekers' interest in network security. For countries such as Australia, cyber security work and the interest of job seekers are also growing at a similar rate. In India and other countries, the number of cyber security jobs has greatly increased, but the interest of job seekers has not increased significantly. In other countries, such as Israel, the interest of job seekers has increased, but the number of recruits has decreased.

Jobs with high titles and engineering jobs are highly paid. Next, analyze the post salary data, and get the highest salary post 10 in the field of network security. Although these jobs belong to high-paying technical industries, their salaries are still staggering-almost all the top ten jobs have an annual salary of $6,543,800.

The highest-paid network security position in the United States is application security engineer, with an average salary of $65,438+028, which is the hottest position in network security work in 2065,438+028. These engineers are mainly responsible for reviewing and testing the security of the code in the application. Each smartphone has an average of 80 applications installed, which is still in short supply.

Followed by the director of information security, the average annual income is $65,438+$027,855. The person in this position is responsible for the development, implementation and operation of the information security system of the whole company.

Cloud engineer is another interesting position on the list (ranked fourth, with an average salary of $65,438+$026,365). They can help individuals and businesses protect cloud storage platforms. 84% of enterprises use multiple cloud platforms for computing and storage, so they need extra help to ensure their data security.

Penetration (average annual salary114,431USD) ranks sixth on this list, also known as "ethical hackers". As the security crisis continues to be threatened, their work is also crucial; Testers will test vulnerabilities in the network security system, just like hackers crack the network.

In order to provide more information to employers, we continue to understand how job seekers find their favorite positions. The data of Indeed website shows which search words have been clicked the most times in the network security industry.

Interestingly, the last search location is not directly related to network security. In fact, the search character with the fifth highest click rate is "full-time"-almost all positions need this word.

"Information technology" is the role with the highest click rate, which is completely suitable for this industry. The second place is "Amazon". Although this is actually the employer who publishes the network security work, and the word does not show the specific work that job seekers need, it still occupies the first place. Ranked third is "Engineer".

How can employers attract high-quality job seekers? Interestingly, other searches unrelated to network security have also narrowed the distance between job seekers and this industry. For example, they will search for "security", "full time", "entry level" and "government". This is undoubtedly good news. There are still many curious job seekers outside the industry, so they may enter this high-demand industry. Therefore, employers should also consider wider recruitment channels.

We share the dry goods learned and developed by AI.

Think of you as a hacker in the movie first, and then you may be more interested.

In fact, the big cow in the field of network security is really cool. Needless to say, a computer controls thousands of servers. It's really a flick of a finger, which makes the opponent disappear.

At present, the network security industry is also very necessary, and the whole network security problem has always been very prominent. Unless you have real skills. In addition, the network security major needs interest, can withstand loneliness and has a certain talent. After all, not everyone can sit on the computer all day to analyze a vulnerability.

In addition, the network security major needs interest, can withstand loneliness and has a certain talent. After all, not everyone can sit on the computer all day to analyze a vulnerability.

If you want to improve, you can also find excellent employment opportunities.

To do network security, we should solve the basic problems: 1 operating system, 2 programming algorithms, 3 TCP/IP protocols, and then talk about security: 1. Encryption and decryption (including file encryption, communication certificate authentication, etc. ) 2. Network intrusion detection and protection. The principle and control of virus are at the application level, which is far from the real network security. Even if you use a Trojan horse to get rid of the U.S. Department of Defense, sometimes your level will not be very good. Let's just say that the people who developed this Trojan horse have a high level. You used x-scan streamer, grey pigeons, black holes and so on, hacker software and viruses to do something you thought was great, but it was really nothing in the eyes of real experts. Study hard by yourself, grasp the direction and don't walk sideways! Work hard!

As a graduate of network security major, I can tell you responsibly that network security major has ranked first in the employment income of graduates in China for several years in a row. My teacher said two words: 1 As long as the network is not banned, there will be network security problems; As long as you are not too lazy in the future, you can find a good job.

Besides, I'll give you a study suggestion. I like to really do network security. It is very important to learn python well. . .

Pseudo base station, disguised as 10086 to send short messages to others.

Network security includes:

1, enterprise security system (most important)

2, data security (disaster prevention backup mechanism)

3. Transmission security (routing hot backup, NAT, ACL, etc. )

4. Server security (including redundancy, DMZ area, etc.). )

5. Firewall security (hardware or software implementation, back-to-back, isolated area, etc.). )

6, anti-virus security

If you want to learn network security, you must first learn English and math well. Network security will be a very popular profession in the future.

Whether it is the international situation, domestic policies or the development trend of Internet technology, the role of network security will become more and more important.

No matter what you want to learn, look at the prospects of this industry first-

In 20 17, there was a shortage of more than 700,000 network security talents in China, and only 120 of the 3,000 universities in China offered related majors, training10-20,000 people every year. Together with 10-20 social organizations, the annual delivery of relevant talents in China is about 30,000, and the gap with 700,000 is 95%.

Due to the problem of the ratio of talent transportation to talent gap in the industry, network security requires less experience for employees, and most of them have no restrictions on academic qualifications. More and more industry practitioners are difficult to make progress at a certain stage and are easily replaced by new people. However, network security is different from other industries in terms of substitutability, and network security engineers will be in short supply in the next few decades. Moreover, except for a few talented people, experience is the first rule to ensure network security.

Secondly, no matter what industry is good, the guide is very important. When you first enter this industry, you need to look up to the best people in the industry and follow their example to become excellent step by step.

No matter what you study, the method of study is very important. When you learn other knowledge,

You can learn according to the method I introduced below:

Four-step learning method

First, study.

Second, imitation.

Third, actual combat

Fourth, reflection

Before you go, no matter what you do, it is very important to find a good guide. A good teacher can make you take fewer detours and then take a step forward.

The first step is to find relevant materials to learn. You know nothing about it. This is an area you haven't touched before. Don't even think about it once, except for genius. After listening, you will have a certain understanding.

Step two, imitate, imitate what and how? Imitate the teacher's operation first. You may not know what it means at first, but you will understand it after imitating it twice.

The third step, actual combat, how to actual combat? Go to our matching shooting range to practice first, and then apply for becoming a white hat after making sure that the shooting range is almost the same. First, tap the public welfare src. Remember, unauthorized websites are illegal. (the master leads the door, and the sentence is personal. )

The fourth part, reflect and summarize the steps you have taken and the problems you have encountered. Do you understand this principle? Or just get into the habit of taking notes in the imitation part.

With the learning method, the next step is to find a suitable learning guide. A good guide and complete system structure can make you get twice the result with half the effort.

Network security major is a very long way. If you want to work in network security, you don't just download some tools and watch tutorials online. You must learn from the most basic, network foundation, from the osi seven-layer model, to routing switching, to firewall, to packet analysis. You must learn linux, because some servers are built by linux. If you want to learn network security, you must first know how to attack, kali. Network security is still popular now, because the network is the easiest to be breached. Network security is also called network security audit. If you can really learn all the way down, the future is still very good. It is best to get cisp or some other certification, but you must have real talent and practical knowledge.
