If you are like me, once everyone is home for the evening, I go around and lock all the doors and make sure the two by four is in the track of the slider door.  As an added security measure we have motion sensors on some large outdoor lights.  Your computer is like your home and there are numerous ways you can protect it from intruders too.

A firewall is a definite must have if you connect your computer to the internet.  Not only ensure you have one, but also make sure the default administration password has been changed.  The default password on a lot of home systems is “password” and everyone knows this, especially those with malicious intent.  Change it to something only you know.  If you need to write it down, be sure to store it in a safe place.

I recommend you find someone who knows a thing or two about in home firewalls and seek their advice on the best way to configure your solution.  Below are some additional items to consider for improving security for your computer:

  • Endpoint Protection – This is a new term describing the next generation of Anti-Malware software.  Make sure you have one running on your computer.  There are many commercially available solutions.
  • Auto Updates – You need to ensure your Endpoint Protection, Operating System and other software applications remain updated with the latest security patches provided by the vendor.  The most convenient way to do this is using the auto update features built into these solutions.
  • Screen Saver Lock – By setting up a password for your computer and enabling the screen saver lock, you keep information on your computer safe.  It also provides you control over who you allow to utilize your computer and when.

My first car, a Chevy Cavalier Z24.  It was a manual and it was so much fun shifting through the gears at a rapid pace.  Today I enjoy driving my sons 1970 Dodge Dart Swinger.  Yes it is a manual transmission too and I have just as much fun racing through its gears like I did my old Z24.  Being an old car, it burns a little oil.  We check the oil regularly to avoid the risk of blowing up an engine.  Computers are like my son’s old car.  Preventative maintenance is also required.  While your computer may not blow up like an engine, it is at risk of failure if you don’t keep its operating system up to date. 

Vendors that manufacture the software for computers regularly release security updates.  These updates if not applied frequently will cause your system to be more susceptible to malware.  If your system is compromised, it can cause your system to behave erratically, become extremely slow, and even become inoperable. As a best practice, set your computer to auto update when a critical security patch is made available by the vendor.

The other software on your computer works the same way.  Vendors frequently produce releases to fix known security flaws.  Take a minute to review the settings within those applications.  You will likely find you can set them to auto update as well.
