There are four questions about the security of network information systems

The main issues related to network and information security include the following aspects:

1.Network system security: Network system security mainly refers to the security problems existing in the computer and network itself, that is, the problem of ensuring the availability and security of the e-commerce platform, including the physical security of the computer, the system, the database, the network equipment, the network service, etc.

2.Network information security: Information security is the problem of information theft, information tampering, information counterfeiting and malicious destruction of information faced by e-commerce information in the process of network transmission.

3.Transaction security: Transaction security is mainly to ensure the reliability, effectiveness and security of e-commerce transactions, and to prevent transaction data from being tampered with or leaked.

4.Identity authentication and access control: Identity authentication and access control is to ensure that only legitimate users can access the corresponding e-commerce platform, while ensuring the security and privacy of users' information.

5.Data security: Data security refers to the issue that important data involved in e-commerce cannot be obtained, used or leaked by unauthorized third parties.

6.Homogeneity of network security technology and risk of technology abuse: The software and hardware products of network information system are highly homogeneous and lack of technical diversity, which can easily constitute the trigger conditions for large-scale network security incidents.

7.Instrumentalization of cyber security threat technology: The instrumentalization of cyber security threat technology has made it easy to realize attack operations, making cyber attack activities increasingly frequent and widespread.

The above are the main issues related to network and information security, and a series of measures need to be taken to ensure network security, such as identity authentication, firewalls, data encryption, intrusion detection, etc. At the same time, it is also necessary to improve users' security awareness and operation skills to jointly maintain network security and stability.

The main issues related to network and information security include the following aspects:

Privacy protection: Personal privacy is an important aspect of network and information security. The disclosure of sensitive information, including personal identity, financial information, health records, etc., can lead to identity theft, fraud, and other issues.

Data breaches and hacking: A data breach refers to the unauthorized acquisition or disclosure of sensitive data, and hacking refers to the act of maliciously hacking a computer or network system to obtain information or damage a system. These can lead to data loss, service disruptions, and trust crises.

Viruses and malware: Viruses, worms, Trojan horses and other malware may enter a computer or network system through links, attachments, etc., to damage the system, steal information or carry out other malicious activities.

Social engineering: Social engineering refers to the use of deception, manipulation, etc., to obtain information or induce others to take certain actions. For example, phishing emails, phishing**, etc. may be used to scam and obtain personal information.

Insecure passwords and authentication: Weak passwords, reused passwords, and insecure authentication methods can lead to compromised or fraudulent accounts, which in turn can lead to personal information leakage and property loss.

Social safety: There are also some security concerns associated with the use of social networking, including disinformation, cyberbullying, theft, and more.

In order to protect network and information security, individuals and organizations should take appropriate measures, such as setting strong passwords, regularly updating software, carefully clicking on links and files, staying vigilant, and strengthening education and training. In addition, we and relevant stakeholders also need to strengthen the construction and supervision of laws and regulations, and jointly maintain the security and stability of the network and information.

Common network information system security factors do not include: economic policy.

Cybersecurity. Network information security mainly refers to the protection of the hardware, software and data in the network system from accidental or malicious reasons, the continuous, reliable and normal operation of the system, and the uninterrupted network services. Common network information system security factors include network factors, application factors, and technical factors.

Cyber security.

Information system security should generally include three main aspects: computer stand-alone security, computer network security, and information security.

1) Stand-alone computer security mainly refers to the physical protection of hardware systems and software systems from accidental or malicious damage and damage in a stand-alone computer environment.

2) Computer network security refers to the security issues in the computer network system environment, which mainly covers two aspects or nonsense, one is the security of the internal network of the information system itself, and the other is the security of the information system and the external network.

3) Information security means that information has not been illegally or maliciously stolen, tampered with or destroyed in the process of transmission, processing and storage.

1. Invasion of privacy.

2. All kinds of criminals attack the network.

3. There are vulnerabilities in the network itself, such as system problems, protocol problems, human management problems, etc.

4. Pretending to be an unscrupulous company to sell the user's privacy for a profit.

5. Monopoly operators and illegal companies are in the same stream.

6. System defects, the network system is composed of the language coding and support software of the calculation and balance machine, and the logical errors, side deviations and defects in its design cannot be completely avoided. Many Trojan viruses also take advantage of this loophole to find vulnerabilities in the system and attack its weak points, so as to illegally steal data and information.
