Here are a few steps you can take to keep your children safe online:
Check the privacy settings of any website they may be using, and ensure everything is set to the highest level of protection.
Ensure that your children have strong passwords which only they know and cannot be guessed by anyone else.
Establish boundaries for your children, such as limiting time they spend online and discussing with them which websites they should not visit.
Supervise their activities online. Consider monitoring certain websites and checking their online accounts.
Keep the computer in a shared family space, so that your children are not tempted to access inappropriate content in private.
