The gastroenteritis has not been cured. I have been relying on montmorillonite powder before. I thought it was better today, but I stopped the montmorillonite powder. As a result, I started to have diarrhea immediately after I stopped... I feel like I will get gastric cancer when I get older.
The probability should definitely be very high.
So, I will update it later today, and then just refresh this chapter.

If users do not pay attention to the security risks in computer network engineering, it is likely to provide opportunities for network intrusions. Threats to computer information security. Therefore, this article discusses the security issues and solutions of computer network engineering.
1 Overview of computer network engineering security
At present, computer networks have been popularized in various fields of our society. For computer network engineering security, its specific meaning is relatively rich. For example, as far as business operators are concerned, the computer network engineering security protection system in their eyes should be able to meet the protection requirements.
The need for their various business information not to be stolen; as far as individual users are concerned, the computer network engineering security protection system in their eyes is more focused on ensuring the security of the user's own privacy and data. But in general, computer network engineering
The security of computer information systems is a strong guarantee for the security, stability and integrity, effectiveness and confidentiality of computer information systems [1]. As far as the current situation of computer networks is concerned, computer data
Gradually, there is an obvious trend of centralization, and the network environment is gradually showing an obvious trend of complexity, which has brought many hidden risks to the information security of computer network projects. Especially in the early stages of construction of many computer network projects,
Engineers only comprehensively consider the adaptability and practicality of the network, but do not give deeper consideration to the security of the network. This may lead to inconsistencies in the design, configuration, and application of computer network engineering in the later use.
Information security problems arise due to reasonable factors. Therefore, the construction of computer network projects should not only ensure that it can implement timely and comprehensive recording and storage of various information data, but also provide sufficient network protection services, ranging from hardware, software, etc.
Start with a data information transmission medium to technically ensure the security of computer network projects.
2 Security issues in computer network engineering
1 Problems in computer operating systems and resource sharing…
The operating system is a key part of the computer and has a non-negligible influence on the overall stability and safe operation of the computer. Therefore, it can be said that computer network security is closely related to the operating status of the operating system. If there is a problem with the operation of the computer operating system, it will cause problems for the computer network.
Bringing major security risks. In current computers, Microsoft's Indos operating system is widely used, but the genuine version of this system is expensive. Many enterprises and individual users use pirated Indos as their computer operating system.
, and these pirated operating systems usually do not have sound security configurations, which may lead to the occurrence of some network security risks. Various problems may occur during the operation of the operating system, such as problems with system account management, port
Setting problems, etc., will have adverse effects on the overall security and stable operation of the computer system [2]. Computer resource sharing has a certain two-sided nature. While it brings a steady stream of resources to computer users and provides sufficient convenience,
It also brings security risks and seriously affects the security of computer network operations. As far as the concept of resource sharing itself is concerned, it mainly refers to a process of obtaining a variety of data information and resources through open forms. It can be seen that,
Openness is its most prominent feature, which provides an opportunity for Internet security killers such as Trojans and viruses. When computer information resources are shared, computer users' privacy settings are low, and malicious intruders can pass through
Illegal means can easily invade and destroy users' computer systems, especially intrusions and damage to computer servers, bringing major security risks to computer networks. In addition, because resource sharing will also be reflected in computer hardware, software, terminals, etc.,
Malicious intruders can even start from the terminal and destroy the computer's hardware and software through illegal means, causing computer users to be unable to use the computer to complete the normal transmission of various information data, causing losses to computer users.
2 Destroy with the help of p\/ip network protocol
The coordinated operation of network protocols has an indispensable impact on the security and stable operation of computer systems. At present, in terms of the development of computer network technology, the application of p\/ip protocols is very popular. But when designing computer network systems
In the process, designers often fail to comprehensively, comprehensively, and in-depth consider the openness, interconnectivity, and security of computer networks. It is especially easy to ignore the security of computer networks and set them up as a trusted network environment, resulting in protocol failure.
Insufficient security itself brings security risks to computer networks and provides opportunities for malicious intruders [2]. Malicious intruders can use the computer server to steal various important network resources, and even maliciously tamper with computer users' personal information.
Information data, causing computer users to be unable to accurately transmit various information data, such as intercepting connections, stealing IP addresses, etc.
3Computer virus issues
The problem of computer viruses is an important security risk for computer networks. Computer viruses have a certain similarity with biological viruses in reality, that is, they attach to computer files and infect other files in the computer through self-replication. This virus spreads
It has a certain degree of secrecy, and computer users often cannot detect it in time. Computer users may infect their computers with viruses when they receive emails from unknown sources or browse some web pages. After the virus enters the computer, it will replicate itself.
Basically, the virus is transmitted to other files of the user, causing serious damage to the computer network. If the computer user does not use anti-virus software to complete the timely and effective cleaning of the virus, it may cause the computer network system to be paralyzed. At present, with the virus
As programmers’ computer technology levels continue to improve, computer viruses are still being updated and upgraded, which brings serious challenges to the update and optimization of anti-virus software and the security of computer network engineering.…
4 Security issues related to cloud computing
Users will also face certain security issues when applying different cloud computing service models or deploying cloud computing service models, which can be mainly divided into two aspects: cloud provider security issues and user security issues, but in general, not all
Most of the problems are concentrated on the single aspect of cloud providers or users. The main responsibility of cloud providers in this process is to ensure the stability and security of the cloud computing network infrastructure, while users should set up identity authentication with a certain degree of reliability.
Passwords to ensure the security of their own data and cloud applications. When users use public clouds to save data or log in to applications, they should host the information on the corresponding cloud server. However, in the current context of artificial conflicts and increasingly prominent business competition
, users’ information security faces more serious threats. From a technical security perspective, multi-user cloud environments can easily cause serious computer network security problems. Different users are often isolated from each other and will not affect each other. However,
In the context of the increasing development of the cloud era, these users may still "drop in" intentionally or unintentionally, causing information leakage. For this part, all data maintenance work is currently handled by third-party platforms, such as cloud encryption and digital certificates.
Encryption, etc. Users can choose appropriate encryption methods based on the importance of their own data to maintain the security of Internet data transmission.
3 Solutions to Computer Network Engineering Security Issues
1Build a complete computer network security defense system
In view of the current security issues in computer network engineering, a complete computer network security defense system should be further constructed. The details are as follows: (1) Setting up a complete firewall to prevent hackers from accessing a complete firewall system can become a powerful guarantee for the security of computer network projects.
Firewall generally refers to a protective barrier composed of hardware and software equipment on the public network interface from the internal and external networks [3]. It is a typical network access control device that can build security between IRAs.
The gateway realizes strong protection of the computer internal network, prevents hackers from intruding, accesses the computer internal network, and maintains the security of the computer network. (2) Strengthen the intrusion detection system. The intrusion detection system is also an important part of the computer network security defense system. Computer users
Intrusion detection systems can be used to identify unwanted activities in a timely manner and impose certain restrictions on computer activities to ensure the safe operation of computer networks. Computer users can also use hybrid intrusion detection methods to establish network and host-based
The intrusion detection system makes the computer network security active defense system more three-dimensional and achieves strong protection of the computer network. (3) Strengthen security scanning. After setting up a complete firewall system and intrusion detection system, computer users should also regularly complete
Computer security scanning strengthens the screening of loopholes and security issues in the operation of computer systems, eliminates various security risks at the first time, repairs loopholes, and ensures computer network security. (4) Optimize the use of encryption technology Encryption technology is also a computer network
An indispensable part of the security defense system, its operating system security level is 2, which can accurately identify computer users and effectively control their registration, thereby maintaining the security of the computer network. Large database management used in encryption technology
The system is indosnt, unix, which can effectively encrypt all kinds of sensitive data in the computer system, ensuring that computer vulnerabilities will not be exploited by hackers and viruses, ensuring that the database will not be destroyed by illegal intruders, and ensuring the accuracy of information and data transmission.
efficiency, thereby ensuring the security and stability of the computer network system.…
2 Strengthen the prevention of computer viruses and repair loopholes in a timely manner
At present, in the context of continuous changes in computer network technology, computer network security issues are also showing a certain trend of complexity. In particular, computer viruses have an obvious trend of complexity, which can disguise themselves as files and URLs that are difficult to identify and induce computer users to
Click, browse, and then spread the virus to other files in the computer. It is also more difficult for anti-virus software to detect and kill increasingly complex computer viruses. Therefore, in order to effectively prevent computer viruses, computer users should start with themselves,
Improve virus prevention awareness, regularly upgrade anti-virus software, and try not to browse suspicious web pages and emails to reduce the possibility of computer virus invasion from the source. Currently, in our country, the more mature computer anti-virus software includes kv300,
Kill, etc., users can use anti-virus cards to dynamically monitor computers and discover computer viruses in time. In addition, when a vulnerability in the computer network system is detected, computer users should repair the vulnerability as soon as possible and should also use it in daily use.
Anti-virus software scans computer systems and strives to discover and repair vulnerabilities as soon as possible, prevent viruses and hackers from invading in an all-round and multi-level manner, and maintain the security of computer networks.
3. Use the access control system to store and back up data.
When dealing with various security issues that exist in computer networks, computer users can use access control systems, that is, authentication systems and access control gateways, to achieve effective restrictions on information resources in all aspects of computer networks. Specifically, computer usage
When using various information resources in computer networks, users must undergo identity authentication, which can ensure the accuracy and effectiveness of the resources used by computer users. Computer users should adopt effective methods to solve problems in computer networks.
In order to solve the various existing problems, we must make detailed plans for the computer network usage traffic, and continuously optimize and adjust it according to the actual situation to ensure that computer network resources can be more fully utilized [4]. In addition, connections with l functions can also be
Click to implement adjustments, use IP addresses to restrict users, and use administrator passwords to complete regular modifications to avoid various threats to the computer network system during operation.
