Reality is scary
The only true reality is that the only secure computer is one that isn't networked, in an alarmed room with no doors and that isn't turned on. Given enough time and money ANY intrusion is possible. Dmitri Alperovitch's post on the McAfee Blog Central, really hits the nail on the head:
"After painstaking analysis of the logs, even we were surprised by the enormous diversity of the victim organizations and were taken aback by the audacity of the perpetrators. Although we will refrain from explicitly identifying most of the victims, describing only their general industry, we feel that naming names is warranted in certain cases, not with the goal of attracting attention to a specific victim organization, but to reinforce the fact that virtually everyone is falling prey to these intrusions, regardless of whether they are the United Nations, a multinational Fortune 100 company, a small non-profit think-tank, a national Olympic team, or even an unfortunate computer security firm."
