...siihen miksi virukset kirjoitetaan Windowsille eikä MacOS X:lle. Ei se ollutkaan levinneisyys, vaan isompi juttu.
Panin tämän myös oikeaan osoitteeseensa tietoturvapalstalle, mutta kun siellä ei kuulemma saa kertoa ikäviä totuuksia Windowsista, ts. viesti luultavasti poistetaan, pakko panna tännekin.
*** Even harder is creating a virus or worm that could access the OS X system. The reason, Janz and several others pointed out, is in part explained by how Unix-based systems handle multiple users on the same machine.
For instance, Mom, Dad and Sis all can have separate user accounts. This also is true of Windows. But in OS X, only an account with administrator privileges can install software -- and even those accounts cannot access or change applications or data in other accounts, especially not the core of the system software.
Furthermore, only a user with "root"-level permissions has full access to the system, but Apple has this access disabled by default. Most users never will go to the trouble of figuring out how to enable the root user, and don't need to -- as nothing a regular user would want to do requires root-level authority.
Denied such access, the damage that any OS X malware could do becomes limited to the account of the user who runs it.
In other words, even if Dad got hit with an OS X virus that wiped out all his data -- and, remember, no OS X viruses presently exist -- the Mac still would operate, and Mom's and Sis's stuff on it would be untouched.
Also, because OS X always asks the user to type an administrator password before modifying anything in the system, attempts to install malware or alter system files immediately would be flagged.
"The virus would have to be an application," said Alan Dail, an independent senior software engineer in Wooster, Ohio. "You'd have to see that it's an application and make a conscious decision to run it for it to actually do anything."
Windows, the programmers said, has no such protections.***

totta, mutta kaikista ohjelmista löytyy aukkoja ja virheitä, kun etsimällä etsitään eli kyllä sitä macinkin saa nurin, jos taitoa riittää. tuskin sielläkään täydellistä koodua osataan kirjoittaa.
miksi macille tehtäisiin viruksia kun mac ei toimi kuitenkaan!!!!
sun pitäisi mennä jo tunnille? Ettei tulis taas niin paljon ala-arvosia amistokariin.
Joo joo ;)
Jos summaa kaikki otsikot täältä tietotekniikka osastolta, niin puolet varmaan käsittelee sitä mikä ongelma wintoosassa vaihteeksi on
Vaikka windows käyttiksiä on yli 92%:lla maailman ihmisistä, niin silti vain puolet kysymyksistä koskee windows käyttiksiä. -:)
yli 92 % maailman ihmisistä ei ole eläessään koskenut tietokoneeseen. Lue hyvä poika/tyttö vaikka sanomalehtiä tai edes jotain muuta kuin Seiskaa...
