We don’t care about money deposited in the bank. If we ask the bank for money, I believe they will certainly return my funds. However, as shown by Lehman Brothers ’ bankruptcy during the 2008 financial crisis, banks cannot guarantee 100% of depositors’ money. In South Korea, according to the Depositor Protection Act, only 100 million won (about USD 71,000) is protected, including principal and interest per person. Anything beyond that is actually at risk. In other words, money deposited in the bank is vulnerable to losing the principal. Investing means willingly accepting the risk of losing the principal while seeking profit. Whether we like it or not, we are always investing in our daily lives. Just because a risk doesn’t materialize doesn’t mean it’s gone. - Joseph’s “just my thoughts”
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". But it was obviously of no use. This security guideline was recommended by Bill Burr who worked at NIST in the USA, he suggested this way in his report. 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. We have only tried to change the keys despite the simple method meanwhile. 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"
