The Importance of Cyber Security?

3 minutes

Cyber security also know as network security, it has become a significant issue; how to protect our privacy? How to prevent cyber attacks? How can we better enjoy the convenience brought by the Internet? These questions haunt us, and cybersecurity doesn't seem all that scary. But network security is very complicated, not only related to the Internet itself but also closely related to each of us. Today we will talk about network security issues. What is Internet Security? Network security refers to various technical protection measures taken for information systems. It includes information protection, application software protection, communication and information technology assurance, etc.

What is Cyber Security?

Cyber-security refers to the ability of computer systems, communication equipment, networks or their connection equipment, and the information systems in this connection equipment to be free from threats, destruction, interference, and infringement during operation and to ensure their safe and regular process. It is a field of science and technology in which computers are the primary means. With the rapid development and broad application of network technology, various factors that endanger its security have also emerged and developed. Such as hacker attacks and different information security incidents in society have further exacerbated this trend. To raise people's awareness of the importance of network security, popularize network security knowledge and protection skills

1. Information Protection

Information protection refers to the security management of data. Information protection mainly includes the following aspects: First, the safety of servers and networks; Second, the prevention of network equipment, lines, power supplies, and computer viruses inside the network system; Third, in terms of information security, encryption can be used technology to perform cryptographic computations.

2. Application software protection

Application software protection refers to the encryption and decryption of various data and programs in the information system. Application software includes an operating system, application software, middleware, etc. Usually, software protection technology is used in the underlying system; an encryption or decryption function is added to the operating system, and programs and data are encrypted or decrypted. The protection measures adopted for the application software mainly include hardware protection, operating environment protection, etc. Among them, hardware protection mainly includes protective measures for the power supplies of various computers. Other equipment and external devices; operating system protection mainly includes multiple operating methods and preventive measures for the working environment; operating environment protection mainly includes various operating systems in the computer. Protection measures for application software and its installation environment, as well as for different hardware and software devices in the runtime environment.

3. Communication and information technology guarantee

Communication and information technology assurance refers to maintaining and managing the entire system's security. Communication and information technology assurance also includes the security maintenance of the communication network, user data security maintenance and security audit. It is to prevent the computer from being attacked by hackers or due to the intrusion of computer viruses. Trojan horses and other malicious programs, and to perform maintenance work on the system from errors, interruptions or failures to ensure that the host data will not be illegally stolen and modified. For network security issues, prevention is far more critical than remediation afterwards. Prevention can be done from the following aspects:

(1). Formulate system planning and specifications

(2). Strengthen the detection and repair of system vulnerabilities

(3). Effective defence

(4). Improve the security awareness and business skills of network administrators.

4. Information security management

Data security management in computer systems includes

(1) Security protection in data transmission. Including communication encryption, firewall settings, data packet filtering, etc.

(2) Analyze and control the risks that may arise during computer operation, mainly analyzing and controlling system failures, virus attacks, hacker attacks, etc. So that the system will not fail, virus infection, hacker attacks under normal operating conditions, data leakage and other events, and reasonable use of system resources.

(3) Security protection for data storage and backup.


The popularization of the Internet and the continuous development of network information technology, the status of the network in people's daily life is becoming increasingly important, and its role is also growing. However, because people's awareness of network security is not deep enough, there are still some misunderstandings and blind spots in understanding cyber security in a certain period of time. For instance, some people equate the Internet with virtual space and believe there is no danger as long as they do not log in to a simple website. Some believe that as long as they do not click on insufficient information, there is no need to worry about network security issues; and other means to threaten computer information systems. These misunderstandings and blind spots are detrimental to personal growth and easily cause problems such as the proliferation of insufficient information and disordered network order.
