ESPECIALLY Non Hackers should get Datajacks.
Remove Wireless from EVERYTHING, INCLUDING the DataJack.
Route EVERYTHING through the DataJack.
Use a WiFi Comlink with a HARD WiFi Off Switch.
Download data onto comlink, disconnect wifi with the hardware switch so that there is NO MORE WiFi activity going on/in/out about . .
Connect Comlink to Datajack and transfer Data. Pull the plug when done, reactivate Comlink WiFi again.
Run as high as possible FireWall and AntiVirus and any other kind of defence there is on the external comlink.
Have a backup comlink internally, which has no wifi either and route this through the datajack too.
Cluster your ware and the internal comlink together and run an agent with another load of firewall and antivirus . .
Congratulations, you have impressed every hacker on your side and made every other hacker angry.
Honestly, most of this is not necessary, except maybe for your Smartlink and possibly a hacker watching through your eyes. Since pretty much all 'ware is DNI controlled, a hacker can NOT hack your PAN and gain control of your 'ware and hence control of your body. Anyone who tells you otherwise is just doing so in hopes that you won't know any better.
All cyberware comes with a free Direct Neural Interface. Other than occasionally connection to your pan for updates during downtime, turn the wireless on cyberware off, you don't need it subscribed to your pan.
The one perpetual sticky point is smartlink systems, in which the gun needs to talk to the eyes/display system. The easiest way to do this is to skinlink everything involved, that way you can run in hidden mode or even kill the wireless entirely if you don't need to be talking to anyone else. Yes, you can still get hacked if someone touches you, but a hacker in touch range of a combat specialist should get violated six ways til sunday and left in a bloody heap on the floor. Even then, you have to get through security on the PAN, which is why everyone, always, always, always should run firewall 6 and a high end analyse program. That will stop all but the elite, and if you are up against elite hackers thats what your own matrix support expert is for. With good gear and a few basic precautions Joe Matrix ganger can not blind you or make your limbs go crazy.
