Iteration and Optimization: It would be great to do something well on the first try, but humans are not perfect. To do it well, you need to go through repeated failures and successes, and during that process, you have to identify the pattern that works best for you. This process is called optimization. Optimization requires iteration. Efficiency and profits are guaranteed by repeating a process until a particular singularity is achieved, thereby maintaining that level of excellence. The general rule for success in society is to iterate and keep optimizing. Being consistent is the fastest way to improve. - 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"
