is Linux at the heart of our operations here?
at LCR Computer Services, we take security VERY seriously.
Security is more than just keeping the script kiddies out
- we also have to lock out the serious hackers. We also
work at keeping viruses out of your e-mail. To do all this
we need software that just plain works without giving the
bad guys a way in.
look for platforms that have the tools to give us the best
performance while meeting those goals. And we have to meet
those goals without compromising security. In our years
of experience, we've used a variety of OS platforms here
is at the heart of it. It is by far the easiest to secure.
Linux allows us to turn off individual portals for services
we don't need. Windows does not give us that fine control.
Windows NT and 2000 have way too many entry points that
the White Hats have not discovered yet. But the Black Hats
are working very hard to find them.
is an operating system that is not bogged down by its GUI
(Graphical User Interface). Linux does have a GUI interface,
but it can be turned OFF! This leaves it to do its job with
more vigor than Windows. That means Linux can do more with
less computing power. Which means we can handle the load
with less expensive computers and pass the savings on to
does not mean Linux is the OS of choice for everything.
WinNT 4.0 and Exchange 5.5 are at the heart of our e-mail
system. It was chosen because of the excellent anti-virus
tools available for that platform. But we keep IIS (Internet
Information Services, Microsoft's web server platform) off
of those servers. IIS has not been proven to fit our definition
of secure. And that is why we use Linux based software to
provide web based access to your e-mail.
Linux and Perl have proven to provide an easy way to self-monitor
the systems here at LCR. We use Perl and CRON (Linux's scheduling
tool) to closely monitor all operations here. We use it
to do real time monitoring of network connectivity and to
watch for intrusions on our systems. We use it to make sure
all computers are up and the services we provide are available
to you for your use.
Computer Services has always kept an open mind about what
tools and operating systems to use. Linux has proven itself
to be a very useful tool and will be used here until our
ongoing research leads to a better solution.
