I'd be glad to have the following put to rest as an ignoant rumor. I'm sure no Mac guy and a very lightweight Unix user...
A young co-worker who has some "hackish" acquaintances at a large nearby University (ok, I admit several degrees of separation here - story may be bogus) says these OS X boxes are delivered so wide-open they're dangerous. Much more exposed than out of the box Windows XP. The story goes further and claims typical Mac people are so Unix illiterate they don't take even the most basic security precautions.
For example, my co-worker says his buddy sent him an email listing root passwords for about 100 OS X Macs on campus - all school machines. The guy claims it was gathered running a common and rather old script these types kick around, in a matter of seconds.
So setting the ethics of this aside for a second (not easy), I wonder how true this is? Remember, I have the word of a guy taking the word of a shady guy here.
If it is true, how risky is it for a business to put these things online anyway? Seems damned-foolish if true, and I'd think any "hacker insurance" would be voided.
Then again perhaps they're easy to lock down too. But hey, "no IT Department" right?
