Off-Topic: Is WiFi secure for tax work

[geekgirldany]

I've had clients come by with their laptops wanting to access the internet because of various reasons. I never give them access to the wireless network. For one you have given them the password and you hope they would not but it could allow anyone to access the the wireless network. Most routers have to be configured to not allow access from certain ports. Most are not by default. Just not a wise thing to do.

What is the risk? This doesn't give them access to your server. All they can do is use our internet. I am not a techie, so I don't understand why this is a problem.

For me the big risk is if their laptop has a virus you've now exposed your network. One that got a lot of media attention not too long ago was crypto locker. It would encrypt files and then ask for payment to recover the encrypted files. No known work around other than restoring from a backup before the virus encrypted your files (or paying the ransom). If your tax software is being used on the network you may have open file shares - imagine if your tax software was encrypted and you lost access. A virus could also delete everything, upload data to whoever created the virus in a foreign country, or just cause annoyances (pop-up ads all over everything).

Probably most people running a tax office with their tax software shared to a few computers have just made open file shares in windows that anyone could connect to, if they gain network access. Even if there aren't open file shares there's potentially lots of vulnerabilities in software in general you're letting people expose their laptop (and viruses) to that you don't normally make available to would be hackers on the internet.

One thing people do who want to make internet available for others is to isolate the wireless from the rest of their network. Basically the wireless network wouldn't see the wired network and all the computers that need access to anything other than the internet are kept on the wired network.

Depending on how your router is setup, it will allow anyone to anything on your network.. including your server. Most routers will be setup this way.

Giving clients your wireless access code

The far greater risk is you letting a client log into your wireless network with their ipad or laptop.

If using the security system WPA or WEP, it is far more likely the data would be stolen as it is bouncing around the internet than the burst from your computer to the router.

Also, a wireless printer is likely far more vulnerable than the wifi network for the internet.

I misread that as if you were saying using wireless would cause local data to bounce around the internet. Instead I see you're talking about non-local network data being higher risk than local data with encryption. I would agree with that.

As long as it's secured with WPA I don't see a risk from the casual drive by.

WiFi

Thank you all for responding. I'll check with Drake and see if there is a problem using it. I'm not sure this is the route I'm going, but I'd like the option.

MAC Filtering

I prefer a wired network for tax/accounting related work. Some tax software like ATX is not recommending a wireless network.

If you must use a wireless network make sure you use encryption and MAC filtering to prevent unauthorized people from connecting to your network. Remember nothing is 100% hacker proof but you can make it difficult to hack your system.

My internet connection is setup at home and I have a wireless router where I can connect at the office. My office is down from my home. You have to make sure it is secure and set with a password. I am not concerned with someone getting into my system. If a person is determined they could hack the password... just like hacking into you email account. War drivers are looking for open access points with no passwords.

To log into what your doing, they would have to know the Wifi password.

I would like to consider using WiFi in my home for work, but have heard stories about people driving by your home and snatching information from the street. Would you share your thoughts with me about this? Probably, a very dumb question, but I suspect many of you use it and I'd like your input.

Thank you.
