“A lot of folks have an unhealthily casual attitude towards
securing their wireless networks. “Oh, it’s nice to share” some
say. Others think “I have nothing to interest a cracker, so why
bother?” Both attitudes are inviting trouble. There is nothing to
be gained from leaving your systems open to be used as warez, porn
or mp3 servers, or Borged into a spam botnet. Or to find yourself
struggling with slow network speeds because some freeloading hog is
overloading your bandwidth.”
