As KT Internet experiences nationwide access disruptions and all Internet-based businesses are paralyzed, citizens are increasingly concerned that the Internet outage could lead to a social shutdown, with concerns rising that it could lead to not only inconvenience but also terrorism.

At around 11:00 AM on October 25th, KT Internet was paralyzed nationwide. Due to this communication failure, not only was KT's wired and wireless internet access impossible, but all internet-based businesses, including finance, broadcasting, and commerce, were paralyzed.

In the financial sector, account transfers and stock trading were halted, and losses were incurred due to the suspension of payment services and stock trading. In the internet broadcasting sector, internet transmissions were halted, resulting in broadcasting failures.

Additionally, in the commercial sector, card payments and zero pay have become unavailable, and only cash payments are possible.

Delivery apps are also reportedly experiencing disruptions, causing serious damage to lunchtime delivery drivers and restaurants.

This situation has led to an increase in public interest in the Internet, something we normally take for granted.

Internet outages are not just an inconvenience; they can paralyze society, making them a vital public good for our society.

In particular, in countries like ours where all social resources are connected to the Internet and a convenient network has been built, the social chaos caused by the paralysis of the Internet communication network is analyzed to have a greater impact.

The conclusion is that it can affect not only simple communications but also finance, broadcasting, and even the military.

Some citizens felt more than just inconvenienced, but also worried that this was a terrorist attack, and they perceived the internet outage as meaning a shutdown of social communication.

Meanwhile, several possibilities have been suggested regarding this accident, including a DDOS attack, but it is known that the cause of the accident was ultimately a configuration error.

Although the service was restored within an hour of the outage, awareness of cyberattacks is growing.

In 2009, a new type of DDOS attack hit the Blue House and other defense facilities.The wealthy and major domestic websites have suffered from access problems.

DDOS (Distributed Denial of Service attack) is a hacking method that attacks a specific site by causing multiple computers to operate simultaneously. It refers to causing a massive number of connections that the target site's computer system cannot handle, paralyzing the system.

Accordingly, various preventive measures are being discussed to respond to cyber threats such as DDOS, such as applying the latest security patches, using genuine software, maintaining the latest version of antivirus programs, deleting unknown emails, and performing antivirus scans when using P2P programs.

On the other hand, in situations like this where a problem occurs in the Internet company's own system, the preventive measures taken by general Internet users are meaningless, so thorough response, prevention, and maintenance by Internet companies are even more crucial.

Consumers unanimously agreed that this incident has heightened their awareness of internet safety and that the internet, as an essential part of our society, must be managed more safely.
