Lots of factual errors here folks. It's important to distinguish between
personal opinion and fact on matters like this, because some readers are
likely to take the opinions as factual.


First, there are lots and lots of vulnerabilities in Sparc and Solaris,
lots. Have a look at

http://search.cert.org/query.html?rq=0&ht=0&qp=&qs=&qc=&pw=100%25&ws=1&la=&qm=0&st=1&nh=25&lk=1&rf=2&oq=&rq=0&si=1&qt=sparc&col=certadv

so switching to Sparc to avoid exploits is simply not true, and even Sun
wouldn't make that claim.

The assertion that switching to Linux, Unix, or MAC will bring better
security is also not true. Again, have a look that Cern or any of the other
academic / government agencies that track these vulnerabilities.

See

http://search.cert.org/query.html?rq=0&ht=0&qp=&qs=&qc=&pw=100%25&ws=1&la=&qm=0&st=1&nh=25&lk=1&rf=2&oq=&rq=0&si=1&qt=Linux&col=certadv&x=15&y=1

for page after page after page of serious Linux security holes. I freqently
hear that Linux is more secure than WIndows, and it simply isn't true.
I ofter hear people say 'I've never had to apply a security patch to Linux
or Solaris'. In reality this means that there systems are wide open to
attack because there are many many known vulerabilities that are well
documented. In fact, it often means they've already been exploited.

Also, the notion that 64 bit processors are immune to buffer overrun attacks
is not true - it is much more difficult - but not impossible and no, I'm not
going to tell you how to do it.

Think that x86 Windows has more vulnerabilites than Linux?  You might be
surprized if you look and the actual numbers, and even more surprized if you
look at the treads (increasing/decreasing) and the time it takes to get a
patch to a vulnerability.

Think Netscape is secure? Think again

http://search.cert.org/query.html?col=certadv&qt=Netscape&charset=iso-8859-1


Is Mozilla bullet proof?

http://www.mozilla.org/projects/security/known-vulnerabilities.html


Java secure?  You get the idea.


I know this will be controversial since many people have alot of 'emotional
energy' invested in product X or Y superiority. At the end of the day, when
you actually spend some time examing this sort of thing systematically , you
find that most of these sorts of assertions of Product X being more secure
that Y just don't hold water.

Now, about that power transformer..
