Chain Reactions and Links: A phenomenon where one event continuously influences subsequent events, connected by a common link. For example, when the central bank raises the base rate, interest rates at private banks increase, which raises the cost of loans for citizens and leads to higher prices. Interest from central banks, interest from private banks, interest on loans from citizens, and increased production costs are all interconnected, so a change in one part affects the entire system. This is a chain reaction. A decline in one area can cause missed revenue opportunities because everything is connected. The link creates this connection. In the example above, the link is the act of borrowing money, which is essentially a loan. To stop the chain reaction, you must identify and break the link in the chain. - 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"
