I'm going to use a 9.7 IPP as my mobile "computer" and will need to use open WiFi at random locations throughout the day. I am normally very cautious doing this with my Macbook Pro, though I'm wondering what security risks there might be with doing this with an iPP and iOS? 1. On my Mac I turn on the firewall and stealth mode. Is there any sort of equivalent on an iPad? 2. If not, does that mean someone can in theory get into my emails, photos or whatever on my iPad? 3. I'm guessing any non-encrypted text sent via email, messages, web forms can be intercepted by someone. Besides that, is there any other risk of someone doing anything else? Thanks.
