• Throughout this course, and through your own
  research, youll hear how one of the hallmarks of
  UNIX is its out of the box security. Whether
  this is a fact or not depends on who and when you
  ask. You can read an overview of UNIX Security
  here http//www.kernelthread.com/publications/sec
  urity/tunix.html. CERT (Computer Emergency
  Readiness Team) also has published a checklist
  that UNIX administrators can use to monitor and
  enhance the security of their UNIX systems at
  http//www.auscert.org.au/5816.

  operating system is the ability to modify the
  source code of the operating system (this holds
  true for Linux as well). What are two advantages
  to being able to modify the source code of the
  operating system? What are two disadvantages of
  being able to modify the source code of UNIX?
  Give an example of each.

• For use in the weekly individual assignments, and
  to get a feel for what the UNIX or Linux of today
  looks like, we have been using Red Hat Linux 5.
  By this time, you may be considering
  investigating other versions of Linux. For this
  DQ, I'd like you to take a "Linux Distribution
  Chooser" test. It is 6 questions long.
• The chooser is here http//desktoplinuxathome.co
  m/distro.html
• Share with us the answers you chose for the
  questions, and the resulting top 4 distributions.

• One of the biggest "complaints" people have of
  Linux is that there are few commercial
  applications available to compete with what is
  available in their current operating system. Pick
  two application categories (such as Email, Word
  Processing, Spreadsheet, Money Management,
  Graphics, Music, Project Management) and locate
  an open source alternative for each. Give an
  overview of each product (brief - but at least a
  paragraph),

• One of the largest (literally) uses of UNIX and
  Linux are for powering the world's
  supercomputers. Supercomputers are used mainly to
  simulate and perform large mathematical
  calculations. My favorite is the Earth Simulator
  in Japan - I love the idea of simulating Earth's
  conditions. It used to be in the top 5, and has
  now fallen to 68th in power and capability.

• Attached to this DQ you will find a somewhat
  dated, but still useful, lecture I used to use in
  class which focuses on viruses and antivirus for
  UNIX/Linux operating systems. Each of the
  antivirus programs mentioned in the lecture is
  commercial - there is no mention of open source
  antivirus options. Why do you think this is? In
  at least 250 words, give three reasons (and
  support them) why open source antivirus
  technology has been slow to develop.
