Hello, everyone. The meeting will answer your questions. Computer security properties do not include, computer security does not include this many people do not know, now let's take a look at it!

Answer:

1. The semantics of computer security that does not include information must be correct. The most important thing in computer security is the security of storing data. The main threats it faces include: computer viruses, illegal access, computer electromagnetic radiation, hardware damage and so on. 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 clean as far as possible, the temperature and humidity should be appropriate, and the voltage should be stable to ensure the reliable operation of the computer hardware.

2. Introduction:

3. Ways to improve computer security attributes: use different passwords on different occasions, such as online banking, e-mail, chat rooms and members of some websites. Different passwords should be used as far as possible to avoid all data disclosure caused by one password disclosure; important passwords (such as online banking passwords) must be set separately and should not be the same as other passwords; when setting passwords, try to avoid using meaningful English words, initials, birthdays, phone numbers and other easily leaked characters as passwords. It is best to use passwords with characters, numbers, and special symbols. It is recommended to change the password regularly to ensure that the loss can be minimized even if the original password is compromised.

4. Computer security attributes:

5. It mainly includes: data security of host and terminal, data security in the process of communication. The security of the host and terminal data is reflected in: the security properties of the computer include setting passwords, setting identification magnetic cards and keys, setting identification fingerprints and sounds, identifying user characteristic systems, protecting data and some important information left on the host or terminal, to prevent information from being exposed to unauthorized people, and at the same time, information can be used by authorized people as needed. The security of data in the process of communication is mainly to ensure that the information transmission will not be tampered with. In the process of information transmission, bright spot defense can be carried out. One is to encrypt the communication data so that no one but the legitimate recipient can understand its content. The other is to use packet switching on the network, and then change the transmission route through packets to prevent data information from being stolen.

This is the end of this article. I hope it will be helpful to all of you.
