If you’re looking for a super secure, highly anonymous proxy then it can be rather confusing. After all what does constitute such a server, there are no real definitions only opinions.
The first thing to be aware of is that if someone just adds the word secure or highly secure to their description it means nothing. There are literally thousands of one page proxy servers running as default installations on some free web hosting space which describe themselves as secure – they are not. To keep a proxy secure needs time, technical skill and a very real commitment to keeping the infrastructure secure.
For instance, there are loads of people running proxies who never even consider the question of which user context the proxy should be running in. It’s actually very important but surprisingly a huge number of people run their proxy services as root.
This is a very bad idea, not only does this potentially give an attacker a very real chance of obtaining complete control not only to the proxy but the server it runs on. The slightest bug or vulnerability in the service can be exploited – there goes the server, the data, user accounts and logs.
A Step Towards a Properly Secure Proxy
Someone more security aware might run the proxy service in the context of the ‘nobody’ user. The advantage of this account is that it has no real administrative rights or privileges and there the integrity of the server is maintained even if the account is compromised. It does have some rights though and can access public directories and any other directories or services running in the ‘nobody’ user context.
But the real secure way is to create a dedicated user account specifically to run the proxy server in. It would have no other function and importantly no other rights or permissions applied. This protects the server, the logs and any users data that may be on the machine. It’s a simple point but a fundamental step in running a truly secure proxy server and giving you a secure IP address to use – 99% of the proxies you find online won’t be set up like this.
The unfortunate thing is that people tend to imagine that a proxy server that obscures your IP address adds a level of security and anonymity automatically. This is simply not the case and a badly configured proxy is far worse than using no proxy at all. Remember that when you use a proxy server all your data is diverted through that server and everything is probably logged too. It’s a huge risk using a badly configured server, whether it’s meant to be a simple porn proxy or highly secure VPN!
The security of the proxy server is really dependent on the technical expertise of the people who set it up and run it. You’ll never get a secure proxy server for nothing simply because professionals don’t work for free. Kids running proxies on free web space who have no concept of security – do however.
Updated Content and Tags – May 10th, 2013
If you search on the internet you’ll find many proxy sites including plenty of USA based proxies – usually they consist of loads of adverts and a little slot in the middle of the page where you type the website you want.
These sites promise you the following -
- ability to bypass firewalls
- ability to bypass content filters
In reality you’ll normally get none of these although to be fair there are some benefits. Here’s the truth about these proxies and the claimed benefits to help you make your own decision.
If you’re really concerned about security and your privacy then the answer is don’t use these websites. certainly never use them to access any site that requires passwords or personal credentials. These sites normally are set up quickly and easily using a proxy software called Glype. This is simply installed on some cheap or free hosting account and surrounded by adverts in an attempt to make money.
Of course there’s nothing wrong with that but be aware the server is not secured, they are also not highly anonymous and there will be no mention of what happens to the logs and you are trusting that website with whatever data you send through it. In reality all you are doing is adding another risk to your browsing. There are some malicious web sites which exist just to steal any credentials that are sent through it.
The claim for anonymity for these sites can be partially true if they are configured correctly. What they can protect from is the web site you are visiting storing your IP address in it’s logs. The main problem with trying to stay anonymous on the web is two fold – firstly your browsing is logged in its entirety at your ISP, secondly it’s all in clear text so is readable by anyone.
The proxies will sometimes stop your IP address being logged at the web site you visit – that’s it. But in exchange it will be logged on their server which may well be run by a 16 year old in his spare time.
Using Proxies to Bypass Firewalls
This can work in a particularly lax environment but in those cases you probably won’t need a proxy server! If the firewall just blocks access to specific IP addresses or URLs then this might work. However most environments are rather more sophisticated than that. Also the majority of web proxy sites are themselves blocked anyway. They can be useful in countries with basic blocks on popular sites like Facebook and YouTube for example.
Using Proxies to Bypass Content Filters
This is a complete non starter as no web proxy will have the slightest effect here. The problem is that although a content filter also looks for specific web sites, IP addresses and content to block it actually looks at the request itself. Most filters look inside the packet themselves so proxies will have no effect whatsoever apart from getting you flagged by the IT Admins for trying to circumvent any restrictions. There is only one way to bypass a sophisticated content filter and that’s to use a concealed proxy server plus encrypt all your data. The encryption means that the content filter can’t look inside the packet and work out the destination. So if you don’t want to have every thing you do online logged and recorded by your ISP and/or employer then encryption is a must. It’s often used when people access pornography online – particularly popular in the middle East where a porn proxy are standard because of the various blocks implemented by the Governments.
Here’s a question that many people want the answer to – How can I obtain a US IP address? Well hopefully this post will help. If you don’t want an explanation about proxy sites and simply want an American IP address at a very low cost – then try this service – here, for a few bucks a month you can have a host of secure, fast US IP addresses plus Canadian, UK, Australian and lots of other countries at your fingertips.
Many web sites determine what you see based on your location, so for example if you want to watch Hulu – you need to be in the USA. Access is controlled by location so it doesn’t matter if you’re a US citizen, if you’re trying to access Hulu from a hotel in Rome then you’re Italian and you’ll get blocked. This is why changing your real IP address is becoming a much more common requirement, simply because that loads of the best websites restrict access depending on the location of your computer.
So for example anyone outside America may get blocked from a US banking site, and you’d certainly be blocked from accessing US-only sites like Hulu or Pandora.
More and more sites are restricting access based on location, it’s often due to licensing issues. Another reason is economic, many websites operate price discrimination (basically charging different prices to different people to maximise their profits), they obviously don’t like consumers finding the cheaper options!
So if you wanted to access a US only site and you’re outside the US, then you need to acquire a US IP Address. Then you could buy from a US only site or watch something like Hulu or Pandora irrespective of your location. Now your IP address is assigned to you by your ISP when you initially connect, there’s no way to change this without losing internet access.
However although you can’t change your IP address - you can hide your true address and present another one. You do this by connecting via either a VPN or a proxy site, both of these will obscure your real IP address. They both operate in similar ways, the proxy server routes all your web traffic via itself and simply forwards all data in both directions. The VPN is actually a secure, encrypted tunnel which routes all traffic from your computer through the VPN server. Both have strengths and weaknesses. In reality a VPN is more difficult to detect by remote web sites, although this can involve a slight overhead on speed in some situations.
Which one you choose is really dependent on what your requirements are – a VPN gives you security and more access to remote sites. But if you just wanted to access something like the BBC or maybe to watch Canadian TV in the US then a proxy server is enough.
So perhaps we want to watch some shows on Hulu but we are based in Europe, for this particular channel a proxy won’t work as Hulu is able to detect them – so we need a VPN service. Unfortunately there are no free VPN services available unless you can access one through your employer or college. Many multinational companies have VPN/Remote access services to allow employees to access their home location. It’s worth checking this out although you should ask your IT department for clearance . Or you could make your own by installing a VPN service on a rented server or a friends US based computer.
But an easier option is to just select a VPN service which allows access to a wide variety of servers especially if you want to use it with an iPad or mobile device, check this post - Watching BBC Iplayer on Ipad in US. These services are all pretty low cost now and the best ones include servers all across the world. Here’s some things to check out when looking for a decent service :-
- Firstly check that the company have some method to allow easy connection. The decent companies have custom connection software to allow you to connect/disconnect easily.
- Make sure your subscription allows access to multiple servers in different countries included.
- Speed is essential if you’re going to use the service for watching video or any streaming media – try to choose a trial account first to test this.
- Be careful you don’t get locked into renewing accounts – use a payment system like Paypal if you can which you can cancel easily.
Unfortunately although there is now lots of choice, many of these services don’t have the knowledge and infrastructure to support high speed access. Avoid anything that seems too cheap or sponsored by advertisements, always test first with a short subscription or trial.
I basically use two different services which offer both proxy and VPN functionality at a decent price. Basically these will give you a full US IP address plus loads of different nationalities at a click of a button
Identity Cloaker is primarily a security product but offers both proxy and VPN modes for accessing BBC Iplayer, Hulu and all media sites. They have loads of US and even more UK based servers so if you want to watch the BBC Iplayer service then it’s probably your best option. They do have lots of servers in the France, Germany, Australia, Canada and throughout Europe as well though. They also don’t automatically renew your subscription either which I like.
Overplay is another great little company, I like their connection software which is easy to use. Lots of US servers included in the standard subscription. They also have the widest selection of servers although perhaps many won’t use most of them. If you need a server in somewhere unusual they are most likely to have them. The support staff know their stuff and are very helpful.
Both these companies allow Paypal and are easy to cancel when you need. They also had the fastest servers out of the ones I looked at. Don’t worry that they don’t openly advertise the bypassing functionality for sites like Hulu, BBC, ABC etc – it’s deliberate, the services which openly promote this functionality get closed down eventually.
I’m not sure of everyone else but when I hear that someone has been convicted of blasphemy, I instantly think it refers to the medieval ages or at least a long time ago. However this latest news story refers to a composer and pianist who has been convicted of blasphemy by a supposedly secular Turkish court.
The court has convicted the pianist and composer – Fazil Say of blasphemy and inciting hatred, for a series of Tweets that he made last year. The ten month sentence has been suspended however any similar offence would mean he’d be imprisoned, in a Turkish prison.
So what did he say ?
Well one message he tweeted a verse from a Persian poet called Omar Khayyam which attacks the pious and their hypocrisy. I’m not sure if anything happened to Omar but it sounds like 11th Century Persia was a little bit open minded about free speech than present day Turkey.
Other tweets made fun of certain religious practices and in particular teasing people about the Muezzin (the Muslim call to to prayer). All this apparently amounts to blasphemy in the country that was once a beacon for secular rule and free speech in the Muslim world.
Of course the fact that Fazil Say had been openly critical of the ruling party and the Turkish prime minister Recep Tayyip Erdogan, may have something to do with this ridiculous ruling. Other artists and intellectuals are increasing being targeted for any criticisms voiced in public.
Turkey is a wonderful country, however the ideals set out by Mustafa Kemal Atatürk seem to be slowly losing their importance in this country.
I have no religion, and at times I wish all religions at the bottom of the sea. He is a weak ruler who needs religion to uphold his government; it is as if he would catch his people in a trap. My people are going to learn the principles of democracy, the dictates of truth and the teachings of science. Superstition must go. Let them worship as they will; every man can follow his own conscience, provided it does not interfere with sane reason or bid him against the liberty of his fellow-men.
Many organisations have expressed concern, including the European Union. The EU Foreign Policy chief suggested that Turkey must respect the principle of freedom of speech. Fazil Say has not commented much yet, other than to express his disappointment at the ruling. He has suggested previously that he would leave the country if convicted, which of course as an International star he is able to do.
I know lots of Turkish people and have family there, this decision will not be popular. Turkish people are relaxed, fair minded and value freedom of expression as much as anyone. But the sad reality is that slowly Turkey becoming a society where people are scared to speak their mind. Slowly the internet is becoming more and more filtered in Turkey mainly due to pressure from religious groups. If you want to surf the internet without Government filters and controls you will already need to use something like a USA proxy server or similar.
I’ve started to leave my laptop at home nowadays in preference to the wonderful iPad I bought last year. After I got used to the fear of dropping it, it’s become an essential companion – much easier to carry than a laptop, starts up immediately and is basically just a joy for a traveler.
Of course there are limitations, including the well documented Flash problem. However one of my main issues was the fact when I travelled to the USA, lots of my UK sites like BBC Iplayer and ITV just wouldn’t work. Now this isn’t a problem with the iPad specifically but it’s due to the fact that most of the UK media sites block access to anyone outside Great Britain. So I had to figure out how to change my IP address to a UK one by using proxies or VPNs to bypass these blocks.
Watching Iplayer using an IPad VPN
Now I work in IT Security and one of my favorite tools is Identity Cloaker which I also use to bypass all these location blocks. It works great on my laptop and PC but the software wasn’t currently available for the Mac OS or iPpad. However fortunately all of their servers including the US ones are VPN enabled – so all I needed to do was connect to one of those.
Anyway here’s the steps I followed to watch BBC Iplayer from the US -
- Select Settings
- Select General
- Select Networks
- Select VPN
All being well – you’ll be at this screen
So in this screen you can already see one VPN already set up – this one is for the US. But I need to add a UK one so -
Click - Add VPN Configuration
You should then find yourself in this screen -
Looks a little confusing but it’s not actually that difficult. Now two pieces of information are not published by Identity Cloaker for security reasons – but these are in the members area when you log in or email and ask for help if needed.
Here’s how you fill the fields in -
- Description – Give it a descriptive name – usually country name is best.
- Server – This is in the member area for Identity Cloaker users- UK VPN server names
- Account Name – Your Identity Cloaker Username
- RSA SecurID – Ignore this
- Password – Your IDC password.
- Secret – This is in members area for Identity Cloaker users under – VPN Secret Name
That’s all there is to it – just remember to Save the VPN configuration before you exit. It is there ready for you to use, whenever you need a UK address then you just enable the VPN as follows.
So to enable the VPN just turn it on from this screen, switch the slider to on. In this situation we would turn the British one on so we can watch BBC Iplayer outside the UK. Remember when you enable the VPN all data is routed through that server down an encrypted tunnel. You may want to disconnect to do your normal browsing after – although you should use it for secure browsing – online banking etc.
When the VPN is enabled properly then you should see this in the top left corner of your Ipad.
This method will probably work with other proxy/VPN subscription services as long as their servers are set up for VPN access – just ask them for the information you need. To get access on a laptop or PC then check out this other post - BBC Iplayer outside UK.
Or there’s a good video on Youtube –
It’s called – VPN on an iPad.
If you haven’t got an Identity Cloaker subscription – it’s best to try this cheap ten day trial first to make sure you can get it working.
Updated – included extra information on VPN
Well if you like to idle away those long winter nights (and days) in Reykjavik by surfing a little porn online, then you might want to consider moving away. The Iceland Government have decided they want to do something good for their citizens (as opposed to bankrupting the country with a hopeless banking system) and are going to ban pornography from the web in Iceland.
Every time I see these sort of stories my heart sinks, why can’t people just leave the internet alone and let people make up their own minds. You might think that it’s all for a good cause, banning all that nasty porn stuff and everyone will behave and be nice to each other. Who knows they might be right, but what I do know is that censoring and filtering the internet doesn’t work – it never does.
An adviser to Iceland’s interior minister- Ogmundur Jonasson who is drafting the legislation was quoted as follows -
“At the moment, we are looking at the best technical ways to achieve this…..but surely if we can send a man to the moon, we must be able to tackle porn on the internet.”
A comment that first got me thinking, can Iceland actually send a man to the moon and secondly they haven’t got a clue about how to achieve this and what sort of issues they will face.
It’s just another of these populist ideas that politicians have, the fact that when you start censoring and filtering the internet, you also start to erode people’s civil liberties. I have no idea if there is any scientific basis to the argument that no porn on internet = less rape and sex crimes, I suspect very little. However I do know that any content filtering will only work against a minority of citizens and almost exclusively on the law abiding ones.
There are so many ways to bypass these filters, that your average sexual predator will easily be able to access whatever pornography they like. The Chinese Government have invested billions in their Great Firewall of China and yet your average 12 year old Beijing schoolboy can easily bypass them using a simple VPN or high anonymity proxy. Do we have any evidence that Iceland will come up with a technical solution more advanced than the People’s republic of China – obviously it it’s not going to happen.
What will happen is that another Government will have a little more control over it’s citizens, but only the ones who follow rules anywhere. The Iceland government will also have this infrastructure installed so maybe next year they’ll think of some thing else we shouldn’t do online and will add that to the banned list. It always happens you start by banning one thing then it just get’s easier and easier to control more aspects of what people can do online.
It’s negative, oppressive and most of all it doesn’t work…..
If you’re in Iceland, Kuwait, Iran, China or anywhere else where the Governments decides whether you can watch porn, politics , sports or whatever – then try this – Identity Cloaker, it’s not just a simple proxy for watching porn over, but a sophisticated security product that can bypass all sorts of blocks and filters and keep you hidden whilst you do so!
The United States of America is known for its declarative stances on life, liberty and the pursuit of happiness. However, this doesn’t seem to be the case when we spend a lifetime – pursuing liberty – only to be met with the unhappiness of censorship. In today’s modern world, the battle for freedom, along with the war against freedom of expression, has shifted gears online. Repressive regimes persistently undermine global civil liberties; cunningly employing various Internet censorship techniques to appear stagnant and under the radar.
The magnitude of Internet filtering and censorship in any given nation is measured by the OpenNet Initiative, or “ONI.” According their website mission statement, the OpenNet Initiative aims to “identify and document Internet filtering and surveillance, and to promote and inform wider public dialogues about such practices.” There are 5 categories of censorship magnitudes (in addition to various nations profiled on ONI’s website) that are structured upon the following bases:
1.) Lack of Evidence
In this case, there is no apparent evidence that websites are being blocked by the government, though forms of control may be employed. The biggest offending countries of proof-voided corroboration are: Afghanistan, Algeria, Bangladesh, Egypt, France, Germany, Iraq, Israel, Malaysia, Nepal, Nigeria, Uganda, Ukraine, United Kingdom, United States, Venezuela and finally, Zimbabwe.
This category alludes to suspicion of blocked websites by governmental influences, yet without tangible confirmation. A prime example is North Korea, which has a national intranet with approximately 30 approved websites. North Korea is an extremely isolated country, and this separation contributes to the difficulties posed in obtaining substantial information.
This grouping implies that a small number of websites may be blocked, and/or a small number of people may see filtered results. Countries such as Armenia, Azerbaijan, Belarus, Georgia, India, Italy, Jordan, Kazakhstan, Libya, Moldova, Morocco, Russia, Singapore, Tajikistan, Thailand and Turkey serve as the deeming nations under this category.
This category identifies nations that filter search results, while further blocking websites at a regularly-low or moderate level. Countries likely to be considered under this grouping are Burma, Ethiopia, Gaza and the West Bank, Indonesia, Pakistan, South Korea, Sudan and Uzbekistan.
Under this extreme magnitude, massive censorship is implemented by the government. Many websites are blocked and freedom of expression is severely limited. Participating nations include: Bahrain, China, Iran, Kuwait, Kyrgyzstan, Lebanon, North Korea, Oman, Qatar, Saudi Arabia, Syria, Tunisia, Turkmenistan, United Arab Emirates, Vietnam and Yemen.
In an attempt to expose cyber filtering and surveillance practices, OPI monitors and rates four areas of Internet activity, as listed below.
These websites generally centralize around taboo issues; ranging from sexually-explicit content, various forms of betting and drugs. The worst offending countries are considered to be: North Korea, Yemen, Uzbekistan, United Arab Emirates, Tunisia, Saudi Arabia, Qatar, Oman, Kuwait, Iran and Bahrain.
This area pertains to website content that opposes, refutes or negates governmental control. Additionally banned are issues regarding human rights and freedom of expression. Implied transgressing countries are North Korea, Vietnam, Turkmenistan, Tunisia, Syria, Libya, Iran, China, Burma and Bahrain.
iii.) Internet Tools
This degree interferes, monitors and tampers with e-mail; web hosting; search and translation; VoIP communications and social media. In light of the Arab Spring uprising, social media has skyrocketed as expressive platforms that convey both sentiments and information in opposition with imposed, authoritative control. The worst offending nations are North Korea, Yemen, United Arab Emirates, Tunisia, Syria, Saudi Arabia, Qatar, Kuwait and Iran.
iv.) Conflict & Security
This classification includes anything spanning a vast military spectrum, with sectors in opposition, separatist movements and militant groups. The nations assumed under this category are North Korea, South Korea and China.
In a June 2011 issue of the New York Times, the United States was chronicled as a nation engaged in a global effort to “deploy shadow Internet and mobile phone systems[in which] dissidents can use to undermine repressive governments that seek to silence them by censoring or shutting down telecommunications networks.” Additionally, internet censorship can be circumvented by utilizing a proxy server website to access banned data. A proxy server website is an un-blocked server that is outside of the censored geographic area of the user. This website tool enables retrieval of censored data. Another way to informationally-intervene is by changing a censored IP address to that of an IP from a non-censored country. For assistance in visualizing the above information, look at our infographic below which showcases the key points of anti-censorship data. After all, it’s only fair that a democratic nation encourages “freedom of speech” as a globally-applicable entitlement.
Freedom of expression is classed as a basic human right both in UN statute and International law. Of course this doesn’t mean that all countries and governments respect this right – clearly when you look at countries like Iran, China and Syria that certainly isn’t the case.
Post something critical online about the Thai royal family and if you live in Thailand, expect a knock on the door very soon. Egypt, Turkey, Gaddafi’s Libya and lots of other Middle Eastern countries also have take a very keen interest in controlling what is posted and discussed on the internet.
The control is usually implemented by fear supplemented by draconian filtering and censoring technologies. Facebook and YouTube are routinely blocked in lots of countries across the world simply because they are very lightly moderated and actively encourage free discussion.
Forums are also a great way for people to gather and discuss various topics and I want to tell you the story of an Arabic discussion forum called Tomaar.net. The site was initially created as a place for Saudis to discuss philosophical aspects of Islam – here’s a screenshot of it.
The forum became very popular primarily because it was a place where subjects like women’s rights, equality and homosexuality could be discussed by Saudi’s in the context of their religion. It soon started to attract visitors from across the world and became a hugely successful forum for Arabic speakers. Needless to say that site was not very popular with the religious fundamentalists who hated this sort of free discussion – and this included the Saudi Government.
The forum was hosted in the USA, so it couldn’t be closed down by the Saudi Government who did however block all access from any ISP situated in their country. Fortunately the forum users were sophisticated web users and were able to use circumvention tools like Identity Cloaker and TOR to bypass the blocks and filters. Also many users lived outside Saudi Arabia and were not subject to the ban and so the forum continued to grow in popularity.
What Happened Next to Tomaar.net?
Well the forum had a pretty tough time over the coming months after the Saudi blocks were put up. First of all their hosting providers suddenly pulled the plug, no warning just a letter terminating their contract. Then followed a succession of hosting providers but all were unable to keep the forum up for very long.
Tomaar.net was being targeted and overloaded by frequent DDOS attacks. DDOS stands for Distributed Denial of Service and is basically when a web server is overloaded by loads of computers (also called a botnet) all making repeated requests at the same time. The server hosting the forum was being overloaded and falling over.
You can defend against these attacks and in fact they tried valiantly to keep the forum up commissioning specialist companies like Prolexic Technologies to protect the site. However in the end it just became too costly to protect the site against these regular attacks, the Tomaar site died and a lively discussion forum exists only in the cache of sites like the Waybackmachine.
Was the Saudi Government responsible for all this, there’s no direct proof that I know of. However there are many who strongly believe they were behind the attacks. The reality is that is would be extremely easy for a Government to shut down a site like this, you can even buy large DDOS attacks online for a few hundred dollars.
This is perhaps the most worrying aspect that even a site hosted in a country famous for protecting freedom of speech is not safe. It’s so very simple to close down a website if you have some resources available – no problem at all if you’re an oil rich fundamentalist government.
There are many nations who are rather keen on filtering the internet. Of course the examples they usually use are of sites run by pedophiles and criminals, which of course nobody objects to. However it rarely stops there, and once some sort of filtering system is adopted in a country you’ll find that list of sites that are blocked gets longer and more varied. Pretty soon there will be all sorts of extensive censorship being practiced – your Government will decide what you can and can’t do online.
But there’s another issue – the technical side is far from clear cut. There is no definitive best method for filtering on this scale. Here’s a couple of the methods some countries have implemented. Both of the techniques depend on the development of a blacklist (sites that needs to be blocked). So consider – somewhere there’s a little group of people who hold meetings deciding on what should be included in this list. Imagine if these people had strong religious or political beliefs – their decisions could be quite different from your own.
But to utilise this black list you have to find a way of stopping people visiting the sites on the list.
One of the most basic methods is DNS poisoning, an extremely simple method of modifying the domain name tables belonging to the ISP’s.
Using this method you can redirect requests for specific blocked pages to someplace else. So when a user asks for one of these pages his browser is actually misdirected to another server – either with a warning page or simply completely blank.
Surprisingly many of the Scandinavian countries like Norway and Sweden have used this method in the past, although it is also been utilised in Holland and Germany too. It’s an awful way of filtering as it messes around with the core functionality of the internet – DNS. But it’s biggest problem is it’s extremely easy to bypass, point your machine at any non-poisoned DNS server and you will get the right address and be able to access the website. The other obvious issue is that you have to block an entire website as the IP address is not related to a single page. Not easy with many social sites and collaborative platforms like Blogger and WordPress. For example is you want to block a single offensive YouTube video you’d end up blocking most of the site if you use this method.
There are more sophisticated methods of filtering the internet though, companies like BT and Optenet specialize in providing such services such as Netclean. All the solutions work in slightly different ways but fundamentally they all have some sort of method of comparing the requested URL with a list of ‘naughty urls’.
The list is obviously one problem as mentioned above – especially in the eyes of those of us who argue against censorship of the internet. But the technologies can also cause issues as well – a current report from Watchdog International highlighted a few technical difficulties that can happen with one of these technologies.
Here is a few of the instances.
ACMA Test of Blocking YouTube
When the Australian Government trialed the BGP filtering system Netclean White Box, they included a few URLs from Youtube to be blocked. The problem was that because a URL from this site was added, all requests for this domain name (Youtube) then got handled directly through the filter. Normally this wouldn’t be an issue with some low traffic criminal website but because YouTube is so popular the box had to deal with millions of requests – which in the end made the Whitebox fall over.
Wikipedia image was contained byIWF List
The Web Watch Foundation manages a very extensive black list of sites over the web. The list can be used by anybody as a master list of which web sites to block. In this event the IWF added the URL of a Picture saved on Wikipedia. Unfortunately this caused a problem with the BT Cleanfeed system being used, when the system filters the web request it acts like a proxy server replacing it’s own IP address with the request. In one of the tests this meant that Wikipedia got hundreds of thousands of request from a single IP address range (the BT Cleanfeed system) which ended up with it being banned and Wikipedia becoming inaccessible for everyone.
The Web Watch Foundation removed the URL pretty rapidly and realised their error but at least the potential problems were highlighted by it when you start any main-stream censorship and Internet Filtering. There is also the very real issue that such censorship can normally be bypassed very easily by simply using a proxy server if needed.
