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.

Companies that have their own IT Center built and operated an on-premise system. But recently, cloud computing is considered to secure system reliability and reduce management costs. IT resources can be efficiently utilized and paid for used. Therefore, companies were deploying and migrating their intranet services to cloud servers. However, it is also true that cloud migration makes system complexity increase, and system reliability is compromised by the increase of management points. Cloud computing for each service unit was considered as a way to meet an efficient utilization of IT resources without compromising existing system reliability when providing new services. Cloud system enables real-time orchestration, and has excellent security. As a hybrid method that implemented cloud computing while maintaining the existing infrastructure, it was possible to operate an uninterrupted system as a result of system construction, and security was also enhanced. Cloud computing used to as a service unit, that both operational efficiency and functionality can be satisfied.
