Macintosh OS X has fully integrated support for its own Airport card.
Airport cards are really 802.11b wireless networking interface cards,
fully compatible with other brands of WLANs for the PC or Linux. These
cards may have a different name, but they have the exact same problems
as described in the Windows world. Since Airport is really just
another method of 802.11b WLAN, security is still a major problem.
Airport wireless networks must evolve to deal with new security
threats just as much as Windows did. Mac OS X has integrated support
for automatic updates, and Apple is also very good about putting out
automatic security updates to ensure that your operating system is protected
against new threats that come out all the time.
Macintosh automatic update is somewhat less invasive than its
Microsoft counterpart. The operating system is fully configurable to
check on a schedule that you set to see if updates are available. You
have the option to deny these updates if you choose. Just like Windows,
automatic update can even be turned off, but you must actually change
the settings to disable it.
The Mac OS X operating system does offer the same type of stability
and security that you would find in other UNIX-based systems, so this
platform will most likely evolve to implement more security measures to
authenticate users trying to log into the network and make sure that
they really are who they say.
