INVADERS!
There used to
be an old MS-DOS game called Space Invaders. Your guy runs along the
bottom of the screen behind a few chunky bunkers. (This game was only
one or two steps up from Pong.) Whole rows of bad guys lined the top of
the screen and randomly dropped bombs on you.
Protecting my machine on
the Internet feels like a battle with Space Invaders. As the
administrator, you need to shield your computers.
