However, you can flip these directions so that moving your fingers down makes the view move up. Open System Preferences and go to the Trackpad menu. Under the Scroll & Zoom heading, tick the box marked Scroll direction: Natural.

Under the Password Settings heading, set the two drop-down menus to Always Require and Require Password, respectively. Now nobody will be able to install new apps without entering your password.
