Should you wish to keep your child from accessing certain websites – and are not confident they won’t try to sneak around behind your back – then you can use Internet filtering software or even the parental controls built into your operating system to protect them online.
Depending on the controls or software you use, you can filter out specific websites, IP addresses, websites by keywords, (such as adult keywords) or even websites by categories, such as blocking adult sites, crackz and warez sites, and chat sites.
Not only that but you can filter out types of access, such as blocking instant messaging, playing online games or even simply surfing the web. Alternately, you could block all website access except to those sites you’ve whitelisted (in other words, approved) as well as restrict or only allow contact from specific people.
