I wasn't sure whether to post here or in the Web Browsing forum.

I've been using dial-up my whole life. Pretty soon I'll be switching over to cable modem. Before I do, though, I just wondered whether there are any new potential security threats that I'll be exposing myself to that don't necessarily exist with dial-up? That "always-on" thing immediately comes to mind, although I suppose I could always unplug the new modem when not in use.

Any general list of helpful tips to make my migration more secure?

Some cable modems have an on/off switch
Mine does right on top
Just make sure to keep your AV and firewall updated
i'm sure others will offer more suggestions

Nothing is less secure than dial-up.
If the cable modem does network address translation (NAT) that already protects you a lot by its nature.
It gives you a 'private' connection with the cable company servers.

You should have a firewall to block things from the 255 or so customers in your IP range and other junk, but the modem might do that as well.
Or connect a good router to that cable modem for super protection.

My new cable modem does come with a router in case I want to hook up a second computer. But since I won't be doing that, I suppose I could use that as part of my line of defense.

In case I want to get technical with my cable provider ("Does the cable modem provide X?" "Is the router equipped with Y?") what specs should I be looking for in my hardware setup?
