One of the misconceptions people have is that they believe they ‘buy (get)’ things with money. However, in reality, it is an exchange of money for goods. You might question whether these two concepts are similar, but there is a significant difference between them. In other words, it leads people to forget that money is also a ‘good’ whose value fluctuates based on the amount available in the market. This creates an overconfidence in money. In terms of value, money is only as valuable as its role and mission in exchange. If the role of food is to ‘eat,’ then the role and mission of money is that it is endowed with ‘the power to exchange anything.’ If money can’t be exchanged for food, can you eat money instead of food? The standard that allows goods to exchange roles and missions with each other is called ‘price.’ - 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"
