Administrative network failure caused by inadequate maintenance = South Korea

It has been revealed that the failure of the local government computer service, which lasted for 56 hours starting on the 17th, was caused by some ports connecting network routers and cables not working.
Experts pointed out that the latest administrative computer network failure was due to a lack of expertise among civil servants at the Ministry of Administration and Security, and the Ministry of Planning and Finance, which cut the budget for maintenance of public market electronic computing equipment. Some say
The view is that restrictions on large companies' entry into the public market cannot be said to be the cause. The Administrative Safety Department also conducted a complete inspection of old equipment, revised the handling manual in the event of a failure, and created a service response manual in the event of a failure.
We have taken measures to prevent recurrence, including creating a manual. However, some within government organizations recognize that computer accidents in the digital age are at the level of disasters, and that they need to acquire expertise and increase their budgets.
There are a number of points being made. At 3:00 pm on the 25th, the Ministry of Administrative Security held a press conference at the Seoul government building in Sejong-daero, Seoul, to discuss the cause of local administrative computer service failures and future countermeasures.
The company held a meeting to announce that the cause of the failure was an abnormality in some of the ports on the module that connects the router and cable.

Professor Song Sang-hyo of Sungsil University said, ``When transmitting packets from the router of network equipment, we observed a phenomenon where large packets were lost, especially 1500 bytes.
Approximately 90% of packets larger than (byte) were lost. This was due to an abnormality in some of the ports on the module that connects the router and cable. Integrated inspection was performed due to packet loss.
The security server was no longer able to properly receive the packets necessary to provide the service from the router, and due to the cumulative delays, it was unable to perform its work properly.
On the 17th, the Ministry of Public Administration and Security announced that the cause of the administrative network accident was an abnormality in the L4 switch.
However, IT experts need to properly process the various data that comes into the service for each server.
The critic said that if the problem was the L4 switch, which separates the system into two, it was difficult to understand why the recovery was not successful even after replacing it with a new one.
This time, it was confirmed that a router port failed and large-scale packet loss occurred even when connecting cables.
The professionalism of civil servants is causing controversy. (However, the Ministry of Public Administration and Safety has told this paper that the router in question has a lifespan of 9 years, and is currently in its 7th year, so it is unlikely that it has deteriorated.)
Kim Seung-joo, a professor at Korea University's Graduate School of Information Protection, said, ``Originally, we are supposed to constantly check to see if devices are working properly, but up until now, the Ministry of Public Administration and Security has not done a good job.''
That means there wasn't." ``For example, in the case of a building, if a crack occurs in the exterior wall, it is visible and the cause can be immediately identified, but in the case of network equipment or computer equipment,
It is difficult to identify the cause. The National Information Resources Management Institute and the Ministry of Administrative Security should have paid attention to this point."
