Linspire (Linux) This system was installed using the default
settings out of the box. After conducting our own security test, we
discovered that the only open port was 7741, which did not appear to
connect to any service or application. Because this system responded
to ICMP ping requests, there was a low number of attempts to
compromise the system--795 attacks. This was the system which
experienced the fewest attacks in the experiment. No attacks were
successful because there were no exposed ports (services) to exploit.
Their definition of "attack" was probably the usual all-encompassing
nervous-Nellie sort employed by security consultants trying to drum up
business. It's difficult to say for sure, because they don't specify.
At a minimum, "attacks" seem to include anything they classify as
The two consultants engaged by _USA Today_ for this study were former
computer criminal Kevin Mitnick and researcher Ryan Russell, the guy who
tried to fast-talk my Linux user group mailing list about Linux malware,
as I detail in http://linuxmafia.com/~rick/faq/index.php?page=virus#virus5 .
