Comment Use a multilayered approach (Score 1) 260
1. Communicate with your children. Let them know what is acceptable surfing and what is not. Teach them about the good and the bad of the Internet and how to recognize it. Be specific and thorough.
2. Use the Internet router to control their devices access. You should be able to write rules to limit them by the device.
3. Use controls on the pcs and mobile devices. For example on the PC you could use Timekpr.
4. You can log their activity.
What level of monitoring you use depends on many factors. Factors include, but are not limited to: your ability to trust your children, the trustability of your children to follow your rules, your level of paranoia.
Note on item #1. Communication is an ongoing two way street. This means you can't just sit down once with them and unleash them on the world. It means being a parent and actually being involved.
Be prepared for your children to eventually be able to break every control you implement.
Only you know can know what level of monitoring is right, and which is too little and which is too Big Brother.
Eventually they'll be able to figure out how to hack into your PCs or devices and bypass every measure you institute. At which point you should hire them to work for you.
