Abstract

The government tried to close illegal sites and conduct a copyright protection campaign intensively. However, it takes a lot of time to prevent illegal sites to block, and there is a limitation when internet browsers used a secure protocol. In order to implement effective policies, DNS servers and SNI fields were blocked since 2019. But SNI field blocking is not a solution of effective blocking because of technical problems. The risk of invading Internet users' access to information has also increased due to the strengthening of access blocking technology and excessive review by government agencies. The government's method of blocking illegal sites is technically circumvented, so there is a problem in its implementation, and it is necessary to start again from collecting public opinion due to the effectiveness and lack of transparency in terms of control. International judicial assistance should be activated to allow direct disposal of the server operating overseas, not to block access to domestic telecommunication network.
