SETLinc recommends OpenDNS for internet filtering.*
First, know that basic search websites can be full of undesirable material. Consider using a website that provides Google SafeSearch up front - like setlinc.com. Also, avoid image and video search engines altogether - even so-called "safe" versions of these are full of "unsafe" material.
While it has been over 15 years since the commercialization of the internet, keeping the internet clean is still a challenge. The fact is, if you look for something on the internet, you will find it. No matter how disturbing, graphic or dangerous the content might be, it is available on the internet. The same technology that makes useful and beneficial material available and easily found is just as effective in making destructive material available and easily found. What is required is the effective management of internet access so that the useful and beneficial material is allowed, and the destructive material is defended against.
Filtering technology and most technical solutions are not effective on their own. While there are systems that will block some or all of the more common or obvious sources of pornography and other undesireable material on the internet, they do not work 100% of the time. If one looks for something - anything - one will find it eventually in spite of the best filters available.
There are three very effective methods for keeping the internet sourced material coming into your home, and your own mind, clean. It is the authors' assertion that these are the only such effective measures, and they work best when used in combination.
Wireless security is another important factor, as it is important to prevent others from using your wireless internet connection without your knowledge. Use WPA or WPA2 security, as WEP has been shown to be unsecure. All newer WiFi enabled devices support WPA or WPA2 security.
