Excuse my ignorance, since I didn't make it to last SWINOG... the
description on their web site implies the system is using BGP to
distribute the black list. Assuming this just distributes IP addresses
of web servers hosting questionable content, by blocking those, will
that not block content of ALL hostings hosted on that IP address? What
about hosters who also host other services on that IP address, like
perhaps DNS and mail services? I recall a time where an email RBL was
implemented using BGP blackholing, and we can into exactly those
problems...

As far as I understand it from my desk, the box routes traffic 
for listed IP to itself and screens the contents on application 
level. good traffic it left and passed on, bad traffic is 
treated in an unknown manor (dorped, rerouted *don't know*). 
This is why it's an absoltely moronic idea to blacklist large 
sites like wikipedia...

One can clearly see what hapens is you route traffic for a 
website hosted on several hundreds of webservers through a tiny 
little screening frirewall sitting on a tiny little box. *lol*

 As said earlier, IMHO the authorities should purchase the system for all
 serviceproviders. This is not a matter of marketing, this is too serious.

And a matter of responsibility. Everybody using it is responsible if it
blocks the wrong content while everybody not using it is blamed for not
doing anything.

And then there's that other question: Who is supervising the ones who
write the filter lists? What can a small Swiss ISP do if some NGO in
another part of the world isn't working carefully?

Also, make available a 100% open implementation that ISP may look into and
then trust.

(You have quiet a lot of power when biasing the flow of traffic in your
routing mesh to go thru a layer7 box - potentially dangerous if it falls in
the wrong hands).

Like economical/business intelligence (or lack of intelligence).

That's a bit the same problem with having that kind of development done in a
private firm.

The private firm needs money. It may accept to built some backdoor way to
inject some IP's in the BGP mesh for short duration to tcp
reassembly/parse it etc. in the layer7 box (which is a linux box).

Worse, in every software shop I've been, adding a backdoor to a new
development has always a cool (even if childish in reality) effects.
Getting money in the pocket, too. (Solving the rest of this equation is left
as an exercise to the reader :-)

So if the government want to push such a filtering, they will need to
propose a completely open implementation to peer reviews, compiled, packaged
and signed by a team of 5 - 10 peoples taken out of the community of network
operators and end users.

Zusammen,

I quote:

@ Andreas

  ...by using the AntiTerror law...

Please Pony up the clause invoked in this piece of legislation so that we
can observe the context of it - if any. Whatever legislation they used is
not important, it protected a large amount of municipal UK assets. I
wouldn¹t want my money gone with the wind just because you don¹t think it¹s
right and proper!

  What if one day, they decide to block www.ubs.com http://www.ubs.com
because too many UK customers use it for money laundry as example?

Sounds perfectly reasonable. This is not censorship of ones¹ right to be.
This is an example of criminality and the onus would be on UBS et al to
negate it. And the Swiss Government would take action in all probability
long before that came about.

@ Markus

  ...Homeland security here we come...

The social ill¹s seen as endemic in many cities across it (UK)  are brought
about by weakened schooling,  a distinct lack of self-discipline and a
propensity for binge-drinking, wanton vandalism, bodily harm and kebabs each
and every Friday through Sunday. But recent Government (last 20 years or so)
have been unable to deal with it effectively for many, many reasons.

The direct consequence of this has seen CCTV attempt to tackle the problem,
rightly or wrongly. The Egg came before the Chicken in this case. But, of
course, the camera¹s shall stay no matter what.

We discussed this for a while this afternoon in the SP NOC and the
understanding was that many casual users of paedophilia, though not the
tech-savvy harder-core, would, in all probability, be deterred by DNS
re-direction to local-host or another site stating ³SRC IP logged² etc.
Simple to implement and probably largely effective.

I don¹t have a problem with any technology that blocks objectionable
material that is non-consensual to the overriding majority. It serves no
useful purpose and does not infringe my right to be.

 Censuring is dangerous and legally challenging. You either do it all and take

 Censuring under control of someone else basically means you can be blamed for
 results you don't have under your control. This sounds like a ticking time
 bomb.
 
 Just as an example: UK Government has confiscated assets from Icelandic banks
 (to protect the investment UK people have done in Icelandic savings funds
 which went belly up) by using the AntiTerror law as the ground of the claim!
 What if one day, they decide to block www.ubs.com http://www.ubs.com
 because too many UK customers use it for money laundry as example? It could be
 totally legal from a UK perspective and totally illegal from a swiss
 perspective and would have a severe effect for your customers.

Why should they? They better invest that money into something usefull, 
like education, or they could lower the taxes.

 This is not a matter of marketing, this is too serious.

Too serious? Everybody really interested in that stuff will still be 
able to get it using p2p filesharing (freenet for example supports a 
darknet mode which allows you to create closed groups with encrypted 
connections and encrpyted data storage).
Everybody else will never see such content. I've seen a lot of legal 
porn advertisement when searching for technical information on the net, 
but never any single illegal picture.

Like others have mentioned, there are the usual problems of zensorship: 
You can't check if only bad stuff is being zensored (well, I think 
nobody of us would want to see that content anyway), it could be used 
to censor other content (like in that case: 
http://www.heise.de/newsticker/Schweizer-Richter-ordnet-erneut-Website-Sperrung-an--/meldung/101028).
The providers of illegal content are always faster creating new sites 
then the zensors updating their blocking list.

Today we are blaming China for their great firewall. Tomorrow they 
will tell us they are doing the same thing we are doing - blocking 
access to content which is illegal by law.

Btw: It is interesting that the press release doesn't name which 
providers are using that WhiteBox. If it is really that great, why 
don't they say who is using it?

Peter

 Netclean Whitebox funktioniert zweistufig: 1. wird via BGP4 die Liste
 der verdächtigen IP Adressen in die Routingtabelle eingepflegt. 
 Derzeit sind das um die 450 IP Adressen. Traffic von diesen Websites 
 wird auf die Whitebox umgeleitet. Auf dieser erfolgt 2. die DNS resp.
 HTTP Inspection, und die Whitebox ist damit in der Lage, zwischen 
 illegalem und harmlosen Inhalt zu unterscheiden, der sich zufällig an
 der selben IP Adresse befindet.

So it works kind of like eg Arbor Networks' DDoS protection mechanism
(redirect some traffic using BGP, deep packet inspection after packet
reassembly), coupled with data from an uncontrollable source (which is
generally believed to be some sinister government agency infiltrated by
oppressive political regimes).

It's interesting it took so long for commercial products to appear for
the technically obvious solution.

It will be interesting to see how fast well-meaning politicians and
paranoid pseudo police-men will want to filter all that nasty illegal
music from the net. And how long it will be before such machinery is
mandatory for all ISPs.

The excuse that there is no technical solution is gone - it was a lie
all along the way, and most techies knew. Now it's time to face the
consequences.

I see this like another example of fighting evil at the wrong end.
Of course it is important to fight such content but is filtering websites the 
right method ?
I don't think so.

Let be realistic, how many ISPs worldwide are gonna deploy a Whitebox ?
Filtering locally simply means stopping end users to access illegal sites.
Ok, but the sites are still there and everybody else will still have access !
What do we wanna fight ? The access to illegal content or the publishing of 
them ?
Just because some ISPs will filter-out those sites will not reduce the amount 
of kids being abused.
What is worser ? Someone looking at kids being abused or someone who abuse them 
?

I see already Netclean press releases claiming the big success as the list of 
sites will increase,
as at the same time, the guys who manage those sites will not notice any 
decrease in hits...

The Netclean solution is better than nothing but definitely this is not gonna 
make the difference.

First, there's a right to free speech
(http://www.un.org/Overview/rights.html, Nr. 19).
Because the block list is not public, it impossible to identify
whether the problem is
a server that is down and/or misconfigured, or if there is censorship going on.

The road to hell is paved with good intentions, and this is one of them.

Another part is that they aren't solving the problem, much less even
trying to do so. Why block access to child porn sites?

You can just take them down, have the people responsible arrested and
there's no need for complicated technical solutions to a social
problem. Of course that'd probably mean that they'd actually have to
do some work, instead of giving the work to someone else.

Of course, people like you really like to focus on the child porn
aspect, mostly because it marks everyone who disagrees with you as a
potential rapist. Fact is that this technical solution can't even
begin to fix that problem, but creates many others - like the
oppression of opinions not liked by the Internet Watch Foundation or
similar organizations.

mode, punishing people will be much easier than before.


 Just because some ISPs will filter-out those sites will not reduce the amount 
 of kids being abused.

I agree. They should punish people who:

 - Produce such content
 - Pay for such content

...but starting to block random sites is just silly: It didn't work when they
started to use DNS and it won't work this time either...

 And how long it will be before such machinery is
mandatory for all ISPs.

The excuse that there is no technical solution is gone - it was a lie
all along the way, and most techies knew.

Hmm it's not a lightly engineered solution. it was not an obvious one.


One thing to consider is that there are people out there who are ISP's  
just for a bunch of people or for people outside Switzerland.
So I'm not too sure what the solution costs but I'm sure its not  
available for free. I assume its around 10k at least.
Today this solution is easily affordable for the big guys but still  
expensive for the smaller ones (but I assume not out of reach as it  
was assumed).


Tomorrow they want to filter google for the search keyword child  
porn etc. Now go figure how many requests then will go through the  
box...!


The day after, the government thinks its smart and we should go one  
step further and start filtering videostreams by using a box which  
looks at the content. Then such a solution will start to cost  
100'000's of francs (at least once its invented). And down goes the  
deadly spiral. Someone pays the bill. Always.


If we give in to such matters, it means we will be asked more and more  
because everyone thinks its so easy to do technically. But that's not  
the point.


Blocking the sites won't bring the effect compared to the cost to the  
economy. Think of this: we sure have more than 40 ISP's in  
Switzerland. Assuming the box costs 10'000 CHF (and thats a pure  
guess), the cost to the swiss economy is 400'000 CHF (someone pays for  
it and I believe its going to be the end user at the end). Not even  
including the cost of maintaining it. For that amount you can send out  
quite a few policemen to take down child porn sites at the other end  
of the world which would be way more effective.


The law doesn't allow us to wiretap and intercept. So lets not start  
burning our fingers with something which does exactly that . The human  
rights of free speech should be hold high even in the fact that  
someone might stumble on.


One thing which would be interesting to hear is how many requests do  
such site actively block today? How many people have been prevented  
from seeing nasty content? What has this saved Switzerland that those  
people did not see the content? Is this bigger than the cost?


Frankly, since the 15 years I'm using the internet, there has not been  
a single time where I stumbled on to child porn, and if I would, it  
would take me 0.5 seconds to realize and go away. This was probably  
because I was not actively looking for it. So for me (taking the hat  
of a  a normal typical user now), such a solution would bring zero  
value. The value might more be negative because there's the danger  
that something might get blocked by mistake.


The key question is who do you want to protect and from what?

The child porn lover wont be protected. You might make him more  
angry maybe, but it wont change his intention. He might even go and  
rape real children instead because he can't do it in virtuality.  
Everybody else with a normal moral sense who would see such content  
would either close the window immediately and/or call the police to  
take down the publisher.


Closing your eyes in front of a problem wont solve the problem.
Its like selling sunglasses to protect your skin at the beach.
