Network security depends on everyone, everyone is a network security propagandist handwritten newspaper

1. Network password security knowledge:

1. Set a password of sufficient length. It is best to use a mixture of upper and lower case letters plus numbers and special symbols.

2. Do not use information related to you as your personal password, such as your birthday, phone number, ID number, house number, and name abbreviation. This can easily be guessed by people who know you well.

3. Do not use English words with special meanings as passwords, such as software, hello, hongkong, etc. It is best not to use words as passwords. If you want to use them, you can add plural s or symbols at the end. This can reduce the chance of being guessed by the dictionary file.

4. Do not set all passwords to be the same. You can add a prefix to each one.

5. Do not write down passwords to prevent them from being forgotten. It is foolish to write down passwords anywhere except in your brain. 6. Don’t stick to one password, change it frequently, especially when encountering suspicious situations.

6. Don’t let Windows or IE save your password in any form, because the * symbol cannot hide the real password, and in this case, Windows will store the password somewhere using a weak encryption algorithm. in the file.

2. Internet surfing safety common sense:

3. Do not casually add strangers to the friend list of OICQ or ICQ, etc., and do not casually accept their chat requests to avoid being exposed to port attacks.

4. Don’t open email attachments from strangers casually, because it may be a piece of malicious HTML or JavaScript code (it has been found that HTML code can format your hard drive). If it is an executable file, it may be a backdoor. tool.

5. Do not visit some suspicious or alternative sites, because many loopholes in IE can allow malicious web page editors to read sensitive files on your machine. We will discuss this in IE loopholes. What are the benefits of network security knowledge?

What are the benefits of network security knowledge: This benefit is actually reflected in the two aspects of resource sharing and information exchange and timely delivery. Take resource sharing as an example. An office or several offices only installs one printer without delaying work; a company or library only purchases an expensive piece of software, and everyone in the company can use it at will; a train Stations or airline ticket offices collect ticket information and put it online. Anyone can check it online at any time to know how many tickets are available for a certain train or flight. Such things as saving money and reducing duplication of work are all benefits. The benefits of information exchange and timely transmission of information in the network are even greater. Because of the computer network, the People's Daily can send the layout to printing sites all over China and even abroad within a few minutes after finishing printing in Beijing. In this way, you can start printing from the newspaper at around 6 o'clock in the morning. The Internet knows the news that happened half an hour before the newspaper was printed; also because of the Internet, farmers in Huadu can sell flowers to countries all over the world from their homes. Children in Shaoguan can attend the online school of the High School Affiliated to Guangzhou Normal University while sitting at home and receive extracurricular tutoring from special teachers across the country. It can be said that it is precisely because long-distance information exchange and timely transmission can be carried out through the network. In this sense, the network has changed time and space, the distance between people has become closer, the earth has become smaller, and information has become smaller. Much more.
