Figure 27: Disable Internal Microphone
28. Use a dummy plug to plug the Line In jack on the machine.
29. If there is no Line In jack, then the only setting available under the Choose a
device for sound input box will be the internal microphone (if there is
one), and there will be no way to remove that option. In either case, it is
recommended that the internal microphone be physically disabled. As stated
previously, this should only be done by an Apple Certified Technician to avoid
voiding any warranty on the machine.
Next, the Require a password to wake this computer from sleep or screen
saver restriction should be enabled as follows:
30. Click on the Show All icon at the top of the system preferences panel.
31. Click on the Security icon to bring up the security preferences panel.
32. Place a check in the Require password to wake this computer from
sleep or screen saver checkbox.
Note that the above settings are not protected. Administrative privilege is not
required to change them, and the user may change these settings himself. The
configuration for these settings should be clearly indicated in the security policy for
the system, and users should be educated about the need to ensure these settings are
secure. Also, the system administrators may want to check users’ accounts
periodically to ensure users are not changing these settings.
