Your only protection is what is on your computer.With the Aircard in your laptop, there is no hardware firewall or other hardware protection that you can use. A hardware firewall has to go in between the computer and the cable/DSL modem. In your case the modem is the Aircard. So the hardware firewall has to go in between the laptop and the Aircard. Since you plugged the Aircard directly into the laptop, there's no where to "plug in" a hardware firewall. You could put the Aircard in to certain models of hardware firewall that can take PC cards. (i.e.: D-Link DIR451.) But that is not a portable device; it must be plugged in to a AC outlet. In general, you can't add any hardware security device on a laptop with a cellular card.My laptop gets internet either from a Aircard or from Wi-Fi. I use the Windows Firewall and AVG antivirus. For basic websurfing, IMO, this is adequate. You may want to also run a antispyware app, or get a "suite" like Norton 360 or similar, to give you AV, spyware and a (slightly) better firewall. Me personally. I like to keep the laptop "lightweight" and I don't like some of the heavy handed security suites, which is why I like AVG. I believe that while the firewall and AV are adequate in most situations, your best protection is to not let your guard down. Don't go to questionable websites, don't open weird email. Get a Spam filter for your email, if you're using a program like Outlook or Outlook Express. (Web based email is a little safer.) Phishing and identity theft are as much of a concern than virus'. Phishing and ID theft will probably come through email or other webpages and won't be stopped by firewalls, AV or changing IP addresses. Think of it like a firewall is locking your car and AV is a arming your car alarm. But if you park your car in a rough neighborhood, your hubcaps will still get stolen. And none of that will protect you from having your windows broken. Your protection is prevention. Don't go to the bad neighborhood, don't go to the bad website. (That's an oversimplification, but I hope you get the point. )Summary, I think you're ok. You might be able to add more security, but it would probably be software and not hardware. Or add more security through "knowledge and vigilance." Beyond that, your only other protection is to not go on the internet. But that's like leaving the car in the garage and not driving it. You're gonna have to drive the car sometime, so just be a defensive driver. (Defensive websurfer. )
