"Microsoft operating systems have often been attacked for their
vulnerability, but the perception that the software titan's systems
are insecure is changing as the company shores up its servers and
applications. Meanwhile, supposedly stronger Unix and Linux systems
have suffered security breaches of their own."
"Experts say that businesses, government and individuals using
both closed-source Microsoft-based operating systems and
open-source systems such as Unix and Linux are tightening security,
but the debate over which system is strongest continues."
"Proponents of both types of operating systems are also
finding themselves in the predicament of having to balance security
factors with usability, which sometimes invites hackers when the
scales tip too far toward usability."
