When I first mentioned to a colleague of mine that I was writing a book on JavaTM security, he immediately
starting asking me questions about firewalls and Internet DMZs. Another colleague overheard us and started
asking about electronic commerce, which piqued the interest of a third colleague who wanted to hear all about
virtual private networks. All this was interesting, but what I really wanted to talk about was how a Java applet
could be allowed to read a file.
