If routed to your ibroadband there is the risk
that some script kiddy or other scally will use your connection
to piggy back to do dodgy things. Not to your data but from your
connection so law turns up on your door. Some security is recommended..
Same reason you should have personnal firewall software. Don't make
life easy for these b*stards. There is a practice called war driving
where you put a laptop in car & drive around mapping unsecure networks
to use. The sooftware for this is easily available (and
legitiamtely used by security analysts & net
admins)
