How I keep my kids safe online with free tools and common sense.

I am Dadmin.  I have three children varying in ages from 1^st grade to high school, so I’ve been dealing with strategizing on the best way to exercise my geekery to keep my kids safe.  I use a few different items to ensure I am keeping abreast of my children’s online lives.

1.  I talked to them about proper online safety.  Things like : Don’t talk to strangers, don’t publish things like your last name, address, or phone number, don’t accept any files from anyone, and you must give me  a current password for any accounts you want to have.  Like any good EULA, I make them agree to all my demands before they get access to anything.  I also let them know that I will be tracking them.  What they say, who they talk to and where they go.  This is the most important step and involves no technology whatsoever. 
2. Open DNS.  Domain Name Servers are utilized as a sort of phone book for the internet.  You enter www.zmogo.com and your internet browser goes to the DNS server and looks up the IP address (ex:  10.1.1.1).  Open DNS is a free service that I can point my broadband router to that also allows me to control what sites they can and can’t get to.  Setting it up is simple.  Just go to http://www.opendns.com and follow their instructions.  It takes just a minute or so to do.  Then log in to the Open DNS account and begin to limit the sites your home network can get to.  It took us a bit of time to fine tune it to our needs.  I entered in some sites that were not adult, but just not where I wanted them to go, plus selected some categories to prevent large sections of adult material and such from being accessible to them.  This covers a majority of the items I didn’t want them getting into.
3. Real VNC.  (http://www.realvnc.com) Commonly used for remote administration of computers, I set up a Real VNC server on each of the computers so I can take a peak at what they are doing at any given time.  I made them all aware that I can do this and that they wouldn’t know I was there watching, so even if they were doing something to negate my other strategies, I could catch them red-handed and punishment would be revocation of Internet privileges.
4. Since our oldest is a fan of Instant Messaging, I required that all his conversations be saved to a server.  I did this in a setting that said something like Archive conversations and then you choose a location.  I can then track actual conversations he’s having with his friends and can ask questions about people he chats with online.  Sure, he can turn off the archiving on his computer, but if I stop receiving updated message logs on the server, I know he did it and can reprimand him, and turn it back on.  Every instant messenging system is different, so find out where this setting is on the tool your child uses.
5. Keeping the computer in an open space is always the best idea.  This makes it far less tempting to try to get around the controls that are in place is someone is watching.
6. Lastly, I install a keylogger, which captures all the keystrokes on that computer.  It is done silently behind the scenes and ensures I can see EVERYTHING that is going on on that computer.  I like keyloggers like Home Keylogger (http://www.kmint21.com/keylogger/) or  KGB Keylogger (http://www.sharewareconnection.com/free-kgb-key-logger.htm)

I am sure to let them know that I am tracking their keystrokes as well and using any software or hardware to avert it is in direct violation of the EULA we agreed about prior to accessing the internet. 

Yes, I may have gone a little overboard and utilizing all these avenues is not for everyone, but if using this to keep tabs on your kids who are hiding things from you can prevent big problems, then I am all for it.  Honestly, just showing them what I can do to track them is enough to keep them out of trouble because they know they can’t get away with anything.
