There are a lot of criticisms that the 'duplication measure' was not done properly in regards to this Kakao incident.

By creating multiple copies of the same data and storing them in different places, we had to prepare for a crisis, but we couldn't.

However, it was confirmed that the government server and backup server containing almost all information of our people are located in the same building, only on different floors. 



This is reporter Jeong Hye-jin.



<Reporter> This



is the National Information Resources Agency in Daejeon.



There are about 10,000 servers with digital information from government departments.



It is the heart of digital government.



The government 24 app, which issues a copy of resident registration, family relationship certificate, and building register, also has a server here.



The Daejeon headquarters has 27 agencies including the Ministry of Public Administration and Security, the Ministry of Health and Welfare, and the Public Procurement Service, and the Gwangju Center has servers of 25 agencies including the Ministry of Foreign Affairs, the Ministry of Unification, the Ministry of Justice, and the National Police Agency.



The manager also said, "Normal servers are doubled, and high-importance servers such as government24 are tripled and quadrupled."



Data is being backed up to up to 4 servers in real time.



The problem is that the backup servers are in the same building, on a different floor.



The government said that the power supply would be different for each floor, but this cacao crash happened as the entire building was cut off.



[Hyunseo Yang / Vice President of Kakao: Isn't there a little bit of contrast in this part where the whole server goes down after a fire...

If the Daejeon main office is destroyed at once due to a fire or earthquake, the data stored in another area should be backed up once every 20 to 30 days, and the data stored in another area must be brought to Gwangju to operate the disaster recovery system.



Real-time crisis response is difficult.

[Kwon Heon-young/Professor, Graduate School of Information Security, Korea University: (Daejeon, Gwangju, Gongju, etc.) It is necessary to prepare the three centers to have a mutually simultaneous backup system so that recovery can be smoothly performed in



preparation for disasters.]



He announced that he plans to open additional centers in Daegu and Gongju around this year to operate a server in the form of a cloud with real-time backup.
