Victoria’s Secret once created underwear worth 1.9 million USD, adorned with diamonds and jewels. Of course, wearing such underwear in real life is impractical and may not sell, but once Victoria’s Secret produces it, media outlets worldwide will promote this underwear. When considering the promotional impact, 1.9 million USD is not wasted as a publicity expense; the cash may be gone, but the jewelry-adorned underwear remains an asset, and brand promotion occurs globally, making it a genuinely profitable venture. Moreover, the existence of 1.9 million USD in underwear means that even if Victoria’s Secret products carry a higher price than competing brands, consumers may feel less price resistance. Spending money wisely is just as crucial as earning money. To understand the relationship between costs and assets, one must learn accounting. - 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"
