The current situation of computer security development and the factors affecting computer network se

There are three main aspects that commonly affect computer security.

1.Virus spreads. Viruses are one of the biggest threats in the current network field, and it is difficult for computers to restore their stored information and data once they are attacked by viruses.

The so-called virus, that is, some destructive and offensive programs, it appears in the form of an instruction, **, which can cause great damage to the computer and the information stored on it, and even make the computer crash, and as long as a computer is infected with a virus, it can quickly spread to other computers through a certain way.

2.Trojan invasion. A Trojan horse is similar to a virus and is an attack program, but unlike a virus, a Trojan horse can be manipulated by humans, and the person who publishes the Trojan can obtain the user's information by controlling the computer, and make a profit by reselling the information, committing fraud, or stealing trade secrets, causing losses to the user.

In addition, Trojan horses can slow down your computer because they take up your computer's memory, causing your computer system to run poorly.

3.Unauthorized and unauthorized access. Access to computers is generally restricted, and some users do not hesitate to use illegal access methods to increase network usage for a certain purpose.

Illegal access can indeed bring some benefits to users, but there is no security detection system for illegal access, which can easily make the computer attack and cause greater losses.

At present, the global information security industry is in the information assurance stage

Global information security has gone through three stages: communication security, information security, and information assurance. In the early 20th century, this stage mainly emphasized the confidentiality of information, and information security was mainly communication security; After the 60s of the 20th century, the rapid development of semiconductor and integrated circuit technology promoted the development of computer software and hardware, and the main goal of this stage was confidentiality, integrity and availability; Since the 80s of the 20th century, information security has derived other principles and goals such as controllability, anti-repudiation, authenticity, etc., and information security has been transformed into considering its system construction from a holistic perspective.

The share of global IT spending on information security fluctuates

According to Gartner's annual IT key indicator data, from 2016 to 2020, the proportion of global spending on information security and risk management technology and services in total IT spending fluctuated, and in 2020, the proportion decreased from the previous year. Gartner notes that this does not mean that enterprises are spending less on security, but that the growth in security spending is lower than the growth in overall IT spending.

Note: The proportion data in the chart is the median across industries.

The software and Internet services industry accounts for the highest proportion of total IT spending

The key indicator data also shows that the proportion of security investment in different industries varies greatly, among which the proportion of security investment in the software and Internet service industry is significantly higher than that of other industries, accounting for a large proportion in 2020. The remaining industries accounting for more than 6% are utilities and insurance, with the transportation industry accounting for the lowest proportion of safety investment.

Global IT security spending is expected to reach $189.2 billion in 2024

In recent years, the continuous growth of cyber threats has led to the rapid development of the global information security market. The structure of information security products is becoming more and more abundant, the number of manufacturers is increasing, and the market size and the proportion of information security investment continue to grow.

From 2017 to 2020, global spending on information security has been on the rise. According to Gartner and IDC, global spending on information security reached $133.8 billion and $132 billion, respectively, in 2020.

According to IDC**, in 2021, the global investment in IT security-related hardware, software, and services (in terms of cybersecurity) will reach US$143.5 billion, and is expected to reach US$189.2 billion in 2024 as the world** and enterprises pay more attention to cybersecurity year by year.

A few of our like-minded friends thought that they should go to Cisco, Rising, Symantec and the like after graduation in their freshman year, otherwise they would have turned their backs on their ideals, but there was no one who still held this idea in their senior year. The main thing is that everyone has discovered what they really like to do in the process of learning professional courses, and unfortunately it is not information security - to make an inappropriate analogy, the work of information security is a bit like property security in reality, that is, walking into a skyscraper, pushing every door, trying to pick every lock, and studying every blueprint and manual that can be found, until you know how to prevent thieves, and, by the way, how to do thieves, you know in your heart - this is a matter of interest at first glance, A boring errand for a long time (of course, engaging in theoretical research is another matter, that is basically mathematics), requires patience and enduring interest, and there are not many people who are willing to do it for the rest of their lives. And this industry, the masters are all in the folk, just imagine that you finish the Ma Zhe Mao during the day, and come back at night to get a copy, and suddenly one day you find that your computer was killed by a virus written by a sixteen-year-old boy 10,000 kilometers away, and I don't quite understand why, it is easy to have the frustration that experts can't fight civil science.

So later on, everybody started to feel that they were living somewhere else, that they weren't here, that we should kick something else. So those who go abroad go abroad, those who engage in hardware do hardware, and those who make maps make maps, but they are still doing computer-related things. In short, we have two classes of majors, about 40 people, although there are many people who change careers to buy insurance after graduation, most of them still stay in the IT industry, including after graduate school, both at home and abroad.

Large companies such as Tencent, Huawei, IBM, etc., small companies do GIS, data mining or pure outsourcing, and it seems that only one person actually went to the security company, and there should be another guy who went to the security bureau. From the perspective of employment status, there are really few people who can really use the knowledge of professional courses such as number theory, information theory, cryptography, and virus prevention in this science every day.

Now better and better informatization, well, the prospects for the development of the computer security industry are very good, well, can also be anti-theft, and can be safe those data well, in general, it is very safe.

Personally, I think the development prospects of the computer information security industry are still very good, now every student has a very basic pinyin design for computer learning, and there are some talents in action production, I believe that the computer information security industry will develop better, they will improve the understanding of this industry through their own learning and technology, so as to master some necessary knowledge development, indicating that the prospects of the company in this industry are still very good, whether it is welfare or treatment, you can, and you have a lot of income, Hopefully they can get accordingly.

Computers are an industry that the future is inseparable from and will continue to evolve. Computer information security is an industry that needs to evolve, so its prospects are still very important.

The future of the computer information security industry is bright, but unfortunately the threshold is very high.

The reason why I say this is because information security is a very hands-on job, and it is difficult to get started and the knowledge is relatively extensive.

If you don't have a solid foundation, you can't even do an internship or even understand it, so the bar is high. Needless to say, the future is bright, and several security bulls I know now earn from millions a year.

In the ordinary programmer, no matter how hard they work in the right direction, it is difficult to achieve this number, because information security is too focused on personal work experience and effectiveness (except for package projects).

Surely good, the current society is developing towards information automation. This industry will get better and better in the future, and it will become more and more profound.

It is challenging, there are more jobs, and there is a lot of room for development.

1.After graduation, students can go to large telecommunication service providers and large communication equipment manufacturing enterprises at home and abroad for technology development, and can also go to other enterprises and institutions to engage in design, maintenance, education and training in the field of network engineering.

2.After graduation, students can engage in technology development, teaching, scientific research and management in the field of software engineering in many software enterprises, state agencies, information technology departments and education departments of large and medium-sized enterprises and institutions at home and abroad.

3.After graduation, students in the field of communication can engage in scientific research, teaching and engineering technology of communication technology and electronic technology in the information industry, finance, finance, post and telecommunications, transportation, national defense, colleges and universities and scientific research institutions.

4.The direction of network and information security is a wide caliber major, and the main disciplines are information security and network engineering. After graduation, students can manage and provide services in the field of computer network systems and information security in the fields of national defense, military, telecommunications, electric power, finance, railways and other departments.

Advantages: Computer science is of course a major with good employment prospects compared to the past ten years, so whether it is a boy or a girl, the employment is not bad.

Today, with the development of the information age, people can freely find knowledge, chat, entertainment, etc. on the Internet. Especially for today's student population, they are far more dependent on the Internet than middle-aged and older people. The convenience of the network brings us convenience but also brings certain security risks.

Therefore, in this era of high-speed information development, we need to have a good information management ability. In terms of information security, specialized personnel are also needed to manage it, so that the Internet information age will become more secure. Therefore, the information security major was born and gradually developed into a very important major.

There are many people who apply for the information security major, but they don't quite understand what this major can do in the future. In fact, the information security major is one of the classifications of network security, which belongs to the computer class, and cultivates students with comprehensive information security professional knowledge and can engage in higher information management related work. The nature of this major also determines that it is more suitable for science students to apply for the examination, while most liberal arts students cannot apply for computer science majors.

But in terms of employment prospects, I am personally quite optimistic. Because the development of the Internet has reached a very prosperous point, how to ensure the security of our information is a very grand topic.

In the daily study of college students, the information security major also brings a great test to them, because they not only have to learn information security and research Internet information systems, but also analyze and process information security and confidentiality, and are also very proficient in the basic knowledge and basic technology of network security. They need to use various protective measures to protect the security of Internet information network servers. This is also a very hands-on major, and students need to try each research category by themselves, so that they can be handy and accumulate some practical experience in their future work.

Information security and other university majors can play a complementary role, such as artificial intelligence, big data, cloud computing, communication technology, etc. can form a benign complementarity, can help the development of these majors, they must always be based on computers and the Internet, so they can never avoid information security related technologies. So that's a very big category, and it's an aspect that college students like to pursue. Therefore, in terms of future development prospects, it is still very good, and the salary can be effectively guaranteed.

In particular, some large companies and large enterprises pay more attention to the management of network information security, and they need to set up a dedicated team to deal with hundreds of millions of information every day. Therefore, college students who apply for information security majors can develop in many aspects in the future. Because the comprehensive ability of this major is very high, the requirements for students are also very strict, as long as you master the skills, you can find a satisfactory job.

Summary of the current situation and countermeasures of computer network security, computer network security mainly includes system security, network security, information dissemination security, and information content security. The details are as follows: 1. System safety operation system security is to ensure the security of information processing and transmission system, focusing on ensuring the normal operation of the system.

Avoid damage and loss to the system storage, processing, and transmission of messages due to system collapse and damage. Avoid information leakage, interference or interference by others due to electromagnetic leakage. 2. Network security: The security of system information on the network, including user password identification, user access authority control, data access authority and mode control, and security audit.

Safety issues follow. Computer virus prevention, data encryption, etc. 3. Information dissemination security: Information dissemination security on the network, that is, the security of the consequences of information dissemination, including information filtering.

It focuses on preventing and controlling the consequences of the dissemination of illegal and harmful information, and avoids the loss of control of information on the public network. 4. Information content security: The security of information content on the network focuses on protecting the confidentiality, authenticity and integrity of information. Attackers should not take advantage of system security vulnerabilities to conduct eavesdropping, impersonation, fraud, and other behaviors that harm legitimate users.
