This article will explain in detail what computer security mainly includes. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Computer security mainly includes: 1, the security of computer data storage; 2, computer hardware security, the environment around the computer should be kept clean as far as possible, temperature and humidity should be appropriate, voltage stability, in order to ensure the reliable operation of computer hardware.

Computer security mainly includes:

1. The security of computer data storage

The most important thing in computer security is the security of stored data, and the main threats it faces include: computer virus, illegal access, computer electromagnetic radiation, hardware damage and so on.

Because the computer hardware itself is a powerful pulse source that radiates into space, such as a small radio station, the frequency ranges from tens of kilowatts to hundreds of megabytes. Thieves can receive the electromagnetic waves radiated by the computer, recover them and obtain the data in the computer.

2. Computer hardware security

In the process of using the computer, there are certain requirements for the external environment, that is, the environment around the computer should be kept as clean as possible, the temperature and humidity should be appropriate, and the voltage should be stable, so as to ensure the reliable operation of the computer hardware.

The principle of power leakage is that the electromagnetic signal generated by the computer is transmitted along the wire through the municipal power wire, and the signal can be intercepted and restored from the power line with special equipment.

The International Committee for Standardization is defined as "the security and management of data processing systems and technologies adopted to protect computer hardware, software, and data from destruction, modification, and exposure due to accidental or malicious reasons."

Extended data:

Computer security protection strategy:

1. Install antivirus software

For ordinary users, the first thing to do is to install a set of antivirus software for the computer, upgrade the installed antivirus software regularly, and open the real-time monitoring program of the antivirus software.

2. Install personal firewall

Install a personal firewall (Fire Wall) to protect against hackers, maximize the ability of hackers in the network to access your computer, and prevent them from changing, copying, and destroying your important information. After installation, the firewall should be configured in detail according to the requirements.

3. Classify and set passwords and make them as complex as possible

Use different passwords on different occasions, such as online banking, E-Mail, chat rooms and members of some websites.

4. Do not download unknown software and programs

Download software from a reputable download website should be selected, and the downloaded software and programs should be placed in a directory in a non-boot partition, and it is best to use antivirus software to check and kill viruses before use.

5. Guard against rogue software

To select the shareware to be installed on your computer, you should carefully read the terms of the agreement in each step when installing shareware, and pay special attention to those statements about the behavior of installing other software.
