What are the advantages and disadvantages of the Internet?

Internet has broken the differences and barriers in politics, economy, culture and language in traditional international information exchange, and promoted the exchanges between countries. However, because this kind of communication cannot be restricted, it is easier for developed countries to infiltrate politics and ideas into developing countries. At the same time, it also provides convenience for making fake news. There is no news review and verification system here, and any news can be spread through it, and the spread speed and scope exceed the traditional media, which has a greater impact.

Although the Internet is a treasure house of information, it has played a great role in promoting exchanges between countries and developing science and technology economy, but its negative impact can not be ignored. At present, we should mainly deal with these problems from three aspects. First, strengthen management according to law and take legal measures to stop and punish crimes using the Internet. Second, take precautions through technical means, such as special credit card approval for enterprise users, data encoding and encryption, etc. Take measures to isolate confidential computer systems from the Internet to ensure their security. Third, enhance users' security awareness, such as designing a more sophisticated password system and changing passwords frequently.
