Hacker

Definition of Hacker I used to think of hackers as a word for criminals who used the Internet. However, after reading the text of this lecture, I found that hackers are not the only words used by criminals. I searched the original definition of a hacker. 1. one that hacks 2.  a person who is inexperienced or unskilled at a particular activity 3.  an expert at programming and solving problems with a computer 4.  a person who illegally gains access to and sometimes tampers with information in a computer system Types of Hackers 1.

Online Censorship and Privacy

Online Censorship The countries that come to mind when I hear online censorship are China and Russia. I researched online censorship in China near my country. According to the Citizen Lab, a research institute at the University of Toronto, which monitors online censorship, Chinese government censored information about new viruses on the Internet. That has been the case for weeks before the Chinese authorities officially acknowledge the scale of the new coronavirus. It is common in China for social media companies to remove content that is politically sensitive, including criticisms and protests against the government. Citizen Lab revealed that more than 500 words and phrases were blocked in the message app (WeChat) used by many Chinese from late December to mid-February.

The population of the top countries is higher than Japan, indicating that Japan is a country with a very high proportion of Internet users. Understanding of Internet security In the "net common sense test" conducted by Kaspersky Lab, Japan's average score is the lowest among 16 countries in the world. In 2014, the Ministry of Internal Affairs and Communications conducted the Survey on Understanding and Countermeasures against Threats When Using Public Wireless LANs, ranking the lowest among the four countries. Japan is far from the continent and has no experience of invasion by different ethnic groups (especially nomads). On the other hand, Germany, which ranked first in the security awareness survey, is adjacent to nine countries, including France, and has experienced historical friction.
