Safe Computing

Prevent unauthorized use

When you are not at your desk using your computer, anybody else could be using it instead. This gives a person the ability to install a virus, steal files, or perform actions while appearing to be you. Locking your work station or requiring a password when returning from a screen saver are excellent ways of preventing this.

To require a password to return from a screen saver in Windows:
  1. Right click on a blank part of the Windows Desktop and click Personalize
  2. Click Screen Saver on the right hand corner
  3. Choose a screen saver that you would like to use
  4. Check the box next to On resume, display logon screen
  5. In the Wait box, type the amount of time that you want till the screen saver activates. 5-15 minutes is typically a very usable time
  6. Click  Apply and then click OK
To require a password to return from a screen save in a Mac:
  1. Click on the Apple menu and select System Preferences
  2. Select Security and place a check next to Require password to wake this computer from sleep or screen saver
  3. Click on Show All and click on Desktop & Screen Saver
  4. Choose a screen saver from the right column
  5. Set the Start screen saver: slider bar to somewhere between 5 and 15 minutes

Windows also gives you the option to lock the workstation at any given time. To do this, press CTRL+ALT+DEL and click the Lock this Computer button.
