There are many great ways to teach about internet safety, here are a sample:

and many children have had problems:

Children need to be taught how quickly information such as a photo can spread and how these are often not private. They also need to understand that whatever is written or uploaded will be always 'out there' and this can have detrimental effects in their future. A good rule is...ïf you wouldn't show it to your teacher...your nana...your boss...then do not make it public....don't put it on the internet...ever!!!

But can we overprotect them? Who will watch their backs when they are alone?

Should we be doing more to protect our kids or should we instead...... teach them how to protect themselves. 

This is discussed by a teacher of Computing and Systems & Control on his/her Blog, Coding 2 Learn-Kid's can't use computers...

"We could do more though. We should be teaching kids not to install malware, rather than locking down machines so that it’s physically impossible. We should be teaching kids to stay safe on-line rather than filtering their internet. Google and Facebook give kids money if they manage to find and exploit security vulnerabilities in their systems".
