Credit Rating and Required Rate of Return: Suppose you and Warren Buffett borrow money from a bank. The bank will assess your credit ratings differently. Maybe the bank could offer Warren Buffett a loan without interest since it can be advertised as a bank used by the renowned investor. However, it will likely charge you interest because you have a lower credit rating and less fame than Warren Buffett. The interest rate each borrower faces, based on their creditworthiness, is called the required rate of return for creditors. Under the same conditions, the cost of poverty is much higher for the poor than for the rich. Poverty inherently involves costs. - 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"
