Operating System Updates

Every operating system has known vulnerabilities or "security holes".  Some computer programs have these holes as well.  Through these holes, hackers can

  1. Read or delete files on your computer.
  2. Infect your computer with a virus. 
  3. Use your computer to attack another computer.
  4. Many other nasty things.

As of December 3, 2003 the following vulnerabilities or "holes" were known:

Windows 95: 49
Windows 98: 66
Windows 98SE: 41
Windows ME: 37
Windows XP Home: 91
Windows XP Professional: 95
Mac OS X: 74

These holes are closed with "patches" provided by the manufacturer, usually by download. 

How does this apply to UMW?

UMW-owned machines are configured to scan regularly for these updates, and inform you of when they are needed. Whether you operate a Windows machine, or a Macintosh, you will need to stay on top of the latest patches and updates to your operating systems and utilities. Patches and updates are released regularly by Microsoft and Apple to make sure that any current security problems are addressed in your system software.

Luckily, keeping up with this is, in large part, done for you. For instance, if you have a Mac, you will probably see the "System Update" utility run regularly when you login to your machine. And, Windows users will see a message in their system tray that "Updates Are Ready to Insall."

It's good to become familiar with how these installs work so you don't get surprised by them. They are every bit as critical as updating your virus definitions and software. To the right, you will see tutorials walking you through system updates for the Mac or Windows.
