Simple Free Protection for Child Internet Access at Home

Posted by

Overview

The most effective protection is education, but this is difficult when it comes to kids. Plus they are less sceptical and click on pretty much anything.

The system below uses a very simple process of blocking access to dodgy content.

Introduction to DNS

If a machine makes a call to anything on the Internet, it needs to find it using a thing called DNS. This is where, for example www.google.co.uk access is requested, and an IP address such as 173.194.41.183 is returned. The machine then connects to the relevant web server via the IP address.

Changing your DNS server settings on your devices, or better still your home router, will mean that any requests query servers that maintain a constantly updated list of bad sites. A standard IP address is issued (usually presenting a warning page) and not the bad site. Beautifully simple, and very effective.

Family Shield

This free service is provided by OpenDNS and is called Family Shield.

Setting It Up

You will need to use the following two DNS servers on all machines. This can be set on the router, so that all machines on your network use these addresses, or on each machine individually.

208.67.220.123
208.67.222.123

There are more detailed instructions on how to do this on Windows, Macs, Unix, Linux, Mobile Devices, and Wii here and for various brand routers or generic router instructions here.

Not for Businesses

This service is not for business use.

If you are interested in the more feature-rich service that provides further levels of protection, we provide the Umbrella service at £1.70 per user per month.

This service blocks the following:

Malware Malicious software including drop servers and compromised websites that can be accessed via any application, protocol or port.
Drive-by Downloads/Exploits Websites and files that are designed to run code without user intervention.
Mobile Threats Threats that are designed to infect or adversely affect mobile devices such as phones and tablets.
Suspicious Response Public DNS entries that resolve to your internal network space. These are sometimes associated with DNS rebinding attacks, which allow malicious scripts to access your internal network resources.
Dynamic DNS Sites that are hosting dynamic DNS services. This technology can be used by attackers as an evasion technique against IP blacklisting.
Botnet Compromised devices that attempt to communicate with hackers’ command and control servers via any application, protocol or port.
Phishing Fraudulent websites that aim to trick users into handing over personal or financial information.
High Risk Sites and Locations Domains and hostnames that are matching against our predictive security algorithms from the Security Graph.
