The Busted Web Designed to withstand a direct nuclear assault from without, the Internet, foundation for the Web, is exceedingly robust and fault tolerant. But its original design assumed that only trusted research allies worked within, so it has little defense for rogue participants acting against other users. For serious global commerce, this makes the Web pretty much busted-but fixable. HTTP and HTML, the standards that created the graphical, hyperlinked Web, are open and simple.
Any participant can see the source code for any Web page.
That makes it a risky place for critical business applications. To bring real world safety to the Web requires added control and security. Some programmers have been wreaking havoc with code since they figured out they could. Viruses are the most common manifestation of coders gone bad. Pre-Internet viruses were restricted in scope.
