Hacker is a transliteration of the English word "Hacker". The Oxford English Dictionary explains that the word "hacker" refers to a person who tries to use his own computer technology to access computer files or networks without authorization. Now some computer experts explain that "hackers" should refer to people who use computer programming technology to create troubles for computer websites and computer systems and endanger network security. In order to effectively prevent hackers from invading or attacking, we must first understand the ways in which hackers invade, that is, knowing ourselves and ourselves. However, there are many ways and means of hacking, and hacking techniques emerge one after another. However, hacking cannot be separated from four basic ways and means, so the most basic preventive measures are often the simplest and most effective methods. Let's introduce them below.

First of all, about hackers.

Hacker is a transliteration of the English word "Hacker". The Oxford English Dictionary explains that the word "hacker" refers to a person who tries to use his own computer technology to access computer files or networks without authorization. The original hackers refer to those computer elites who try their best to tap the greatest potential of computer programs. They take it as their responsibility to write simple and perfect programs and find loopholes in computer systems, thus promoting the development of computer technology and the perfection of the system. However, with the rise and development of the Internet, the composition of hackers has become more and more complicated, and some hackers have begun to violate network ethics and legal norms and maliciously attack and destroy networks and network users. Now some computer experts explain that "hackers" should refer to people who use computer programming technology to create troubles for computer websites and computer systems and endanger network security.

With the rapid development of the network, network security problems are becoming more and more serious, and hacker attacks are becoming more and more rampant. In the eyes of most people, the ubiquitous hackers have brought great bad influence to the whole network society and social economy.

Second, the hacker intrusion mode and preventive measures

In order to effectively prevent hackers from invading or attacking, we must first understand the ways in which hackers invade, that is, knowing ourselves and ourselves. However, there are many ways and means of hacking, and hacking techniques emerge one after another. However, hacking cannot be separated from four basic ways and means, so the most basic preventive measures are often the simplest and most effective methods. Let's introduce them below.

1.IP address intrusion

This way is the most common and typical way of hacking. No matter how you intrude, such as through a loophole in the operating system or application software, you must first know the house number of your computer, that is, the IP address. Therefore, individual users can completely hide the IP address of their computers so that others can't know it, thus effectively preventing hackers.

2. Email intrusion

This is also a common intrusion method used by many hackers, and it is the second choice when IP intrusion is unsuccessful. It is not difficult to stop hackers from using email. As long as you check and read the received emails, don't easily open emails of unknown origin, and often fix the loopholes in email programs, you can prevent hackers from invading to a great extent.

3. Intrusion by downloading files

It is very common to download files in the internet world, so some hackers will implant malicious programs such as Trojans in some software and put them on the website for people to download. When installing downloaded software, malicious programs such as Trojans are installed at the same time, which is often impossible to prevent. In fact, the simplest and most effective way to prevent this intrusion is to use the real-time monitoring program function of genuine antivirus software and firewall software with network monitoring protection. In addition, it is also important not to download from unknown websites and possibly malicious websites.

4. Use web pages to invade.

It is also a common method for many hackers to take the opportunity to invade by browsing the web. This kind of intrusion can be prevented by setting the security level of the browser and disabling ActiveX and Java programs, which will of course affect the normal browsing of some web pages. Paper reference. In addition, don't browse some irregular and unreliable websites, and using web pages can also effectively prevent intrusion.

Third, the guidance and utilization of hacker groups.

Most people's understanding of hackers is often limited to the evil or sinful side of their malicious attacks, but this is not the case. Because everything has two sides, hackers are not useless to society. As long as it can benefit and avoid disadvantages, hackers and hacker technology are just needed to promote network security. Paper reference.

1. Network security companies need hackers.

Companies engaged in computer network security technology services can't guarantee the quality of their network security services if they don't have the research and development level of hacking technology or the ability to discover potential hidden dangers and dangers of customer systems. Because the object of network security is hackers, it is necessary to have hackers who know the means of attack to prevent hacker attacks more comprehensively. Therefore, the existence of hackers at least promotes the improvement of the service quality of network security companies. Qualified network security experts must have the ability to hack, which is unimaginable for network security experts who don't understand hacking technology.

2. National information security and Internet information warfare need hackers.

The openness and interconnectedness of the Internet determine that hackers can use hacking technology to carry out transnational attacks remotely. Paper reference. Hacking technology can be attacked and defended, which is a very simple truth. Since ancient times, the way to use troops must be both offensive and defensive. From a macro point of view, national security is not only the national security in the past, but also its coverage is gradually expanding, and information security has become a part of national security. The success or failure of future information warfare may depend on a country's overall hacking skills. Similarly, from the perspective of information national security, the development of hacking technology is more conducive to the overall national security.

Network security experts and military experts have realized that the truly organized large-scale information war has not yet arrived, and no one can estimate the degree of damage. In order to win the future information war, in addition to making full preparations in network security technology, other aspects of human and material resources preparation are more important, which also gives hackers the opportunity to give full play to their expertise to serve network security.

Four. Concluding remarks

Hackers not only destroy network security, but also promote network security. Only by making full use of the knowledge, wisdom and technology of hackers can we seek advantages and avoid disadvantages, let them "make the best use of their talents" and build an ideal harmonious society, so as to calmly face the future information war!
