Adequacy : Moderate and appropriate nature. In the early days of the Roman Empire , Emperor Tiberius hosted a grand feast and invited an inventor. The inventor presented a glass as a gift, and the emperor inquired about its features. When the inventor claimed that the glass was unbreakable , the emperor dropped it on the floor. Only one side was dented, and the emperor touched that spot, restoring it to its original condition. Astonished, the emperor asked the inventor, “Have you ever taught anyone how to make this glass?” The inventor replied, “I did not tell anyone.” Then the emperor ordered his execution because if the recipe for the glass were known, the value of the emperor’s gold and silver treasures would plummet. No matter how excellent something is, it can be the worst depending on the situation and context. That’s why adequacy is essential. - 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"
