I agree with that and more!mrkelley23 wrote:For anyone who doesn't know, leaving your wireless access point unsecured MAY be dangerous to your overall computer security. Most routers have significant firewalls, so your personal data may be safe from all but the most diligent hacker, but there are other risks.
Some people have file sharing enabled, just because "sharing" sounds like such a lovely word. What that means is that for a sufficiently motivated intruder, your entire hard drive is available for them to download, if they wish.
In addition, many IP addresses trace to an access point, rather than an individual computer. If someone using a laptop "borrows" your network to, oh, say, make a drug deal, the search warrant and resulting hassle will be served at your house. And while you may eventually be able to show that the user who did the dirty deed was not on your approved list, you won't like the intervening hassle.
What if someone sends a hundred million spam messages from your IP address? You'd not only be terminated by your Net provider, but subject to possible federal prosecution!
