People don’t work efficiently at first. Efficiency comes from trial and error. In other words, if you don’t try, your chances of becoming efficient are slim. The navigation system only works when the destination is entered. More importantly, it only functions well when the starting point is input accurately. The system recognizes the starting point automatically and guides you to the destination, but if the origin is wrong, problems will occur. Change, growth, and progress only happen when you confirm your identity. You need to ask more than ten people around you to understand who you are. The most reliable method is to look in the mirror and wipe away the stains from your face. If you try to remove a stain by guessing, you might sometimes succeed by luck, but that’s just called ‘hard work.’ - 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"
