Re: Linux Security



I read an article on the web a while back (sorry, don't have the URL
and therefore cannot vouch for it's authenticity or accuracy).  It
compared network vulnerabilities of Windows systems and Linux systems
both patched & unpatched.  They connected the systems to the web and
noted that the various unpatched flavours of Windows OS were all
compromised in short order (within hours or less I believe) whereas
the unpatched Linux flavours remained uncompromised.

However when properly patched both Windows and Linux flavours all
remained uncompromised over a period of a month.

Of course add the human factor and any OS is vulnerable.  And the more
services you have running, the more potential vulnerabilities may
exist on any OS.  I was under the impression that the tests dealt with
systems in a laboratory environment (were not used during the course
of the test other than patching and checking for compromise and such).

I qualify this because I know some will no doubt jump in and say how
this system or that system was compromised despite being patched.  Or
the OS itself was not compromised but rather a service running in the
OS, or whatever.

The short and sweet is both Linux and Windows systems have the ability
to be fairly secure in a networked environment (i.e. Internet).  The
largest influencing factor being the human factor.  Security and
usability are typically at the opposit end of the spectrum.  If
implementing of a particular security measure is too difficult for the
average user, or inhibits usability too much, it will inevitably fail
to provide the degree of security it was designed to offer.
