If you have young kids, be careful on what you allow on their devices (ipads, xbox, iphones, etc).
Just the other day, I noticed a young kid (~9yo) watching some type of porn on an iPad, while the parents were paying attention the other kid play softball. I told the mom and she freaked out.
What I am doing for my own kids lately:
-Enable Parental control on their devices, so they can't install, delete or modify any the apps.
-Force a Family Filter through DNS: OpenDNS, Norton, CleanBrowsing ( Lately I have been using CleanBrowsing - https://cleanbrowsing.org - as it enforces SafeSearch + Safe Youtube by default.
-Disable Flash & Java.
-Install an adblocker.
-Check their browser histories from time to time to see whats up. They are all pretty young (under 10), so didn't learn how to clear history yet. I wish there was a way to prevent cleaning up history on the ipad.
Any other things I might be missing?
