In another effort to
defeat Cyber War attacks on their networks, the U.S. Army is expanding the
number of Apple computers, particularly servers, that it uses. Currently, only
about three percent of the army's 700,000 computers are Apples. But because
Apples comprise only about seven percent of all PCs out there, most hacking
tools are written for the more commonly found PCs (about 90 percent of the
market) running Windows software. Apples are not inherently less vulnerable
than Windows PCs, but the hackers have to write special attack software because
of the many differences between Apple software (a variant of Unix) and Windows
(definitely not Unix). But by mixing up Apples and Windows machines in army
installations, another layer of protection is added, making it more difficult
for an enemy to get at U.S. military secrets.
