The Importance of Updates: A Parable

When I assist clients at our front desk, I try to explain the importance of updating operating systems (e.g. Microsoft Windows, Mac OS X, Linux.) Many clients don’t realize that updates are vital to the continued security of computers; you can’t just ignore them. So, to explain what they do, I came up with a fun analogy.

Your computer is like a medieval city with a great wall. The people who designed your city (programmers) want to protect it from from barbarian invasions (virus and malware attacks.)  When they built your city, they erected a giant wall around it for protection (a firewall.) When you started to rule it, you hired a bunch of guards ( you installed anti-virus software.) However, the architects weren’t perfect; there are many small holes in your wall and forgotten tunnels into the city (security holes.) As the architects inspect the city over time, they find these holes and tunnels. Engineers are dispatched around to patch up these holes (Windows Updates) so as to keep your city safe.

The moral of the story: lest the barbarians break in, kill all your guards, and then use your city to attack others, make sure that you install software updates!

Sometimes, you forget to patch the holes in your city or the barbarians find them first. When this happens, you can come to OIT Software Support. Like knights in shining armour, we will happily drive out the barbarians (remove viruses), restore order (fix the problems they created), and give you new and free guards (McAfee AntiVirus.) We’ll also give you advice on how to prevent future invasions; the barbarians are clever.

While all software should be updated, it can be difficult to keep track of it all. There is a program called Secunia PSI. This program will check just about every program on your computer to ensure that it is up-to-date.

If you don’t wish to install Secunia PSI, the most important things to keep updated are the following:
