We’ve got access to the Internet, yeah, but it is not censored. Is that a good or bad thing?
GARETH KEENAN
Bad.
BRENT
Well, it’s not for us to say. All I know is I can type in (Typing) “sex fetish”, yeah…it takes a little while…2 230 matches, yeah. Just click on one, at random. Uggh. (Reading screen) “Dutch girls must be punished for having big boobs.” Now you do not punish someone, Dutch or otherwise, for having big boobs.
KEENAN
If anything they should be rewarded.
BRENT
They should be equal.
KEENAN
Women are equal.
BRENT
I’ve always said that, so..
(Note: the above script is not on-topic with what I’m writing, it was just funny.)
The Internet is the world’s largest public network. Today over 1.1 billion people use the Internet, with many people and businesses in the developed world depending on the Internet day-to-day. This amazing statistic is possible because there are only minor barriers to join the Internet, usually being as simple as paying money to an Internet service provider to gain access. If it so happens that you cannot, or will not do business with a particular Internet service provider, most markets offer a choice of a number of different providers. The size and openness makes one thing very difficult for services on the Internet: exclusivity.
This may come as a shock to you but, by default, any service you put up on the Internet is available to everyone. Everyone. Even your friend’s, friend’s, coworkers. Usually these people have to go looking to find you, but once they have they’re free to do what they can with your website, mail server, streaming audio, etc. That is, if you allow the public access to your service.
Generally speaking, you can block the public from accessing your service. But the service would be pretty useless if nobody could access it. Enter: allow lists.
The Internet is good at inclusiveness. Think of your e-mail account that requires a login and password, or a “public” forum that requires you to register and login. Sometimes blocks are made at a protocol level with firewalls, and sometimes you need to connect to a VPN in order to access services. This can be implemented as simply as requiring a generic password to use the service in question, or by creating a list of acceptable Internet addresses (every computer on the Internet has a number that it can be reached at, like how every payphone has a phone number) or domains (e.g. everyone connecting via “kos.net” can access). For a lot of Internet services, being inclusive is great but it doesn’t make sense for everything–especially websites.
Inclusiveness on the Internet is defined by what you do with a default user; a user that does not qualify for access to your service. If your final rule is DENY then you are running an inclusive service. In the opposite case, when your final rule is ACCEPT, you are running an exclusive service.
Exclusive services are very rare on the Internet. One example that comes to mind is Internet relay chat (IRC) channels (or “chat rooms”). IRC channels offer a “ban” list that can be used to ban users from a channel based on their nickname, identity, and/or host name (Internet address). If you do not match any of the ban list entries you are allowed access to the channel. If you were to try to ban everyone (*!*@*) then no one could enter the channel at all–not even those you want to be able to enter.
Because the public Internet is anonymous, exclusive Internet services tend to only work on ban lists by IP address or domain. There is no way to practically identify a specific person by using the IP address; much like there is no way to identify a driver of a vehicle given a license plate number. You can determine who owns the car, or the Internet account, but you cannot be certain that the owner was using it at the time that you’ve recorded the plate number, or IP address. Because the Internet is large and public it is virtually impossible to exclude using exclusionary methods.
So let’s back up to the Internet being a public network. You’ll recall that I said that means that everything on the Internet is, by default, publicly accessible. This is a truth that all web loggers become aware of quickly, and usually in a surprising manner, if they aren’t already.
Every single web log entry I have ever written has been written with an awareness that it is publicly available. Friends, family, coworkers, potential employers, media, stalkers, and randoms can all equally access my web log. This might not be the way I’d like things but there’s little I can do about this as long as I want this site to be accessible to the anonymous Internet. I want my default rule to be ACCEPT and so I have to accept that everyone, even those I might prefer not, can read my web log.
(Postscript: it also doesn’t help that I use my real, full name in the title and URL; further, I allow search engines to index the site and list it in their search results.)
