One of the principles prevailing in the natural world is that the stronger prey upon the weaker. The strong eat the weak. Thus, people seek strength. However, the statement that the stronger prey upon the weaker is partly correct and partly incorrect. The principle that survival of the fittest prevails in this world suggests that those who adapt survive. “Adaptation” is the strongest thing in the world. - 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"
