When business conditions are good, we need to prepare for tough times, and when business conditions are bad, we need to prepare for better times. If you have experienced misfortunes so far, you should hope that the opposite can also occur. Nothing lasts forever. The universe also changes from time to time, and we must abandon the notion that the society we live in will remain the same.

For the security of the Internet service, we have been asked by the Internet service companies to set the password combined by more than 8 or 10 "uppercase letter+lowercase letter+number+special character".

Furthermore, the user was required to change the initial password set regularly. Despite this measure, the best way of security to protect users' accounts was the notification of the alarm for attempted hacking when the hacker tried.

Today, the world has begun to comprehend that the security problem is not encryption or confidentiality, but simply cyber-dominion control and communication. - Joseph's "just my thoughts"
