If your door has a window or a glass panel, secure it with a decorative grille that has nonremovable screws.

Or, install over the glass a break-resistant plastic panel.

If a window lies within an arm's length of the door, make sure that the door's dead bolt is out of reach should an intruder break the glass in the window and reach inside. 

Cover the window with a curtain or shade to keep prying eyes out.

Always draw all the shades or close the blinds at night to prevent intruders from looking inside to determine what you are doing, whether you are alone - or whether anyone is home.
