Few would argue, I think, that the Internet hasnot changed the world dramatically Everyday we see how free, instantaneous

communication influences politics, socialchange, and daily interactions at a

fundamental level But even with all of this,there still remains a certain level of

provincialism on the net — Americans stick toAmerican websites; Japanese stick to

Japanese websites; you get the idea

Part of this, of course, is due to a simplelanguage barrier; English is an internationallanguage, but it is by no means the only one

To some extent this artificial division of theweb is by design Media producers, like theBBC, often insist on restricting access to theirproducts to certain geographical regions toprotect their business models Distributors(e.g iTunes) are complicit in this, or eveninstigate it Even worse, some governments

Trang 5

insist on restricting Internet communicationand blocking access to international websites.

Trang 6

This guide, then, is my small attempt at

helping people deal with all of these

problems The Internet should connect peopleall over the world, not divide them Whetheryou are a backpacker trying to check youremail from a hostel in Denmark, or a collegestudent trying to get past the Great Firewall

of China, I hope there is some helpful

information in here for you (though if you’rereading this in China, I doubt you need anymore help Good job!)

Trang 7

Government and the Net

We’re going to begin this guide with a

discussion of the most vital issue: that offreedom of expression and governmentalcensorship of the Internet This issue hasbecome one of the most important of ourtime, due to any number of recent politicalevents, and it certainly bears further

discussion here We’ll look at some of thenations with the worst records in this regard,including a few of the lesser known offenders,and look at efforts people have taken tobypass the choking off of information Ofcourse, it will also be appropriate for us todiscuss the ramifications, both good and bad,

of those efforts

Trang 8

National blocking or Censorship

preserving illegitimate power Obviously, truechange comes from a variety of sources, and

Trang 9

it would be foolish to overemphasize the role

of the Internet in regime change like we haveseen in the so-called “Arab Spring.”

At the same time, the behavior of these

regimes toward the Internet clearly impliesthe threat they see in it Numerous nations, all

of them repeatedly tainted by claims of humanrights abuses and political corruption, takepains to restrict the free use of the Internetand often go as far as criminalizing efforts tobypass those restrictions Of course, eventhat has not stopped people hungry for

access to the world’s information

First, then, let’s look at some of these

countries and what they’ve done to deal withthe problem of the Internet

1 North Korea

Trang 10

The Hermit Kingdom

has done so much to

earn its name; it almost

boggles the mind

Information from within

the nation is sparse: the

occasional press

release or intercepted

television broadcast

makes up the bulk of

what we know about what happens insideNorth Korea For an outsider, contact with anaverage North Korean citizen is almost

completely unheard of All of this is purelyintentional on the part of the government, ofcourse, so it should come as no surprise that,according to a 2010 New Yorker article, manyNorth Korean citizens had never even heard ofthe Internet, much less had access to it.There are apparently a few places, like hotelsand PyongYang’s only Internet café, wheresatellite Internet access is available — but

Trang 11

only for non-citizens According to a KoreanTimes article, Internet access is completelyoutlawed for private citizens of North Korea.There are apparently government officialswith Internet access, as there is an officialNorth Korean Twitter account and YouTubechannel, but for most of the businesses andgovernment offices inside the nation the onlyaccess to a computer network is

“Kwangmyong,” a national intranet connectinggovernment offices, banks, financial

institutions and other official entities So, inother words, North Korea has designed itsown, internal Internet reserved only for theelite

2 China

China is, perhaps, the most famous of allnations on this list when it comes to filteringthe Internet In contrast with North Korea’snear total lack of access, China boasts thelargest number of Internet users in the world:

Trang 12

around 513 million people there regularlyaccess the Internet, more than the entirepopulation of the USA (That is still, however,only about 38% of the population — in the USnearly 80% of population has access).

One would think, with the Internet growing soquickly in China, that China would becomeincreasingly connected to the rest of theworld; but one would be wrong The ChineseInternet is very much that: Chinese Less than6% of Chinese websites link outside of thecountry, and China’s native search engine,Baidu, is far and away more popular than anyinternational service

The government is, naturally, deeply

concerned with keeping this situation as it is.External Internet access is heavily censored,both incoming and outgoing Chinese usersare prevented from accessing external webaddresses using a wide variety of techniques:DNS filtering and redirection, packet filtering,

Trang 13

IP blocking and more The effects are notabsolute — there is some access to outsidesites either by accident or design — but eventhen the government is watching For

example, a recent glitch opened up the GreatFirewall to Google+, and users flooded

President Obama’s page with political

comments criticizing the Chinese governmentand various policies Voice of America

questioned the Chinese Foreign Ministryspokesman Hong Lei:

“He repeated Beijing’s position that it protectsChinese citizens’ rights to free expression onthe Internet But he also warned that theyshould express themselves according toChinese laws and regulations “

Free, but

3 Iran

Iran has a long history of Internet blockingand censorship; there are records of the

Trang 14

government choking incoming Internet accesspoints as far back as 2001 The early weeks

of 2012, though, have seen a large upswing inInternet censorship, with access to the secureHTTPS protocol on external sites (such asGmail) restricted, forcing users to log intoexternal services without the extra layers ofprivacy and security encryption offers

Watchdogs like the EFF and OpenNet

Initiative see this escalation as a big steptowards what one Iranian official has calledthe “Halal Internet,” a national network

focused on commerce and business andstrongly guarded against “inappropriate”content — similar to the North Korean

“Kwangmyong” network

In addition to technological attempts to controlInternet speech, of course, there are themore direct controls: bloggers and onlineactivists are routinely detained, harassed andarrested for expressing views critical of the

Trang 15

regime or otherwise unwelcome ideas online.Net cafes are required by law to have securitycameras to record users’ visits, and alsorecord their browsing history and personalusage information for each computer used.The atmosphere of control is near absolute.

4 Saudi Arabia

Not to be outdone by nearby Iran, SaudiArabia filters a broad spectrum of content.Much like Iran, Saudi Arabia maintains apolicy of jailing those who use the Internet foranything smelling of “subversion.” A religiousmotivation is clear: much of the filtering isaimed at sites or content that register as

“immoral” in the strict Sunni nation:

homosexual, women’s rights or pornographiccontent are all blocked, as are sites

containing criticism of the Saudi regime orIslam

Unlike China, which denies censorship whendirectly asked about it, censorship is openly

Trang 16

acknowledged by the Saudi Arabian “InternetServices Unit,” the agency in charge of

Internet filtering You can see for yourself attheir English language website I really

recommend you read that page: it outlinessome very interesting justifications for thesuppression of free speech and information

Lesser known censorship

The countries above are well known, andfairly open, about their control of information

It really shouldn’t come as any surprise thatIran filters web content, or that North Koreakeeps most people offline altogether

However, there are other countries which,while not infamous for online censorship, arestill worth mentioning

Burma (also known as Myanmar), is certainlyworth consideration here Internet accessthere is extremely limited (less than 1% ofpeople have any kind of access to the

Trang 17

Internet) due to economic and political

reasons, but the government has announcedplans to increase access throughout thecountry

It did, in fact, lead to

wider use of the net

for the people of

Burma, but there

was a catch In

2007, during a

period of strong civil

unrest and harsh military crackdowns, theInternet was used to disseminate informationabout the government’s mistreatment of itspeople The government’s response was tocompletely shut the net down

The country has shown some improvementsince transitioning to a new government in

2011, but information about what’s going onthere now is still hard to find

Turkey is also increasingly prominent in the

Trang 18

free-web discussion It consistently blocksaccess to websites containing informationunwelcome by the Turkish government Forexample: sites pertaining to Turkish Kurdishpopulations or labor unions are blocked, as isYouTube on occasion.

Italy might be a bit of a surprise on this list,but then again it also isn’t known for its

freedom from corruption or ill-government Interms of Internet security and privacy, ithasn’t reached the outrage-inducing levels ofIran or China, but at the same time there arelaws on the books which seem completely out

of place in a modern Western democracy.For example, Internet cafes in Italy are

required to take copies of users’ passportsand submit them, along with usage

information, to police agencies The same lawrequires a periodical, comprehensive list of allthe people in the country who use mobilephones

Trang 19

No bloggers are being thrown in jail, but Italy

is not exactly a bastion for Internet freedom

“Reporters without Borders” releases a yearlyreport on “Enemies of the Internet” which hasinvaluable information about national

censorship of the Internet It’s available thisyear at this website I encourage you to readit; it has some surprising information

Should We Bypass This

Censorship?

Trang 20

Having seen how so many countries areengaged in filtering and monitoring Internetusage within their borders whilst blockingcontent from outside, the natural inclination for

Trang 21

geeks and activists alike is to start looking forways around it The fundamental freedom ofthe Internet, with its immediacy and its

ubiquity, has become something of a given for

so many of us that it would be hard to imagineconstraining it

Of course, in an oppressive regime like that ofIran, the obvious value of being able to

exchange information freely with commoncitizens around the world, as well as exposingthe harsh realities of life under such

conditions, should make anyone try to findways to break through government controls.But is that the right thing to do? I’d like to look

at that question in more depth here

Consequences Of Bypassing National Censors

Trang 22

Breaking the law in a country with strictInternet filtering is no joking matter It is nocoincidence that the same countries whichappear on the lists of the worst Internetcensors are also the same countries with

Trang 23

repeated and persistent accusations of humanrights abuses Oppressive censorship is, infact, a human rights abuse.

According to a BBC report filed in 2005,bloggers have been beaten and tortured forvoicing things that the Iranian governmentfound unacceptable China also has a longrecord of jailing Internet-based dissidents asdoes Saudi Arabia

The consequences are thus very serious forthose wanting to use the Internet to be heard

Is it worth it? Consider this seriously beforebypassing any filter

Ethics Of Illegal Bypassing

Oppressing freedom of speech online is notdone in a vacuum: it is typically one part of ageneral oppression of human rights Thenations with the strongest filtering and

monitoring systems are those with the worstrecords regarding the treatment of their own

Trang 24

citizens Often, exposing that mistreatmentand making the realities of oppressiveregimes public is one real step towardbringing them down.

Trang 25

The government of Burma knows this That’swhy it took down all access to the Internet in

2007 — to prevent its people from telling theworld what it was doing That’s why NorthKorea and Iran want to create their own,wholly domestic networks

The “Arab Spring” of 2011 demonstrated thatthe Internet can have a (limited yet real) role

in revolution, though of course the real work

of liberation is done by real people, spilling

Trang 26

real blood —that should never be forgotten.But the deep censorship and monitoring of theInternet as a medium of communication is aninfringement of fundamental human right.Article 19 of the Universal Declaration ofHuman Rights states:

Everyone has the right to freedom of opinionand expression; this right includes freedom tohold opinions without interference and toseek, receive and impart information andideas through any media and regardless offrontiers

The United Nations adopted the Declaration in

1948, and every member state has agreed touphold it since then

So whether it is as a tool for organizing

protests and exposing oppression to promoterevolution, or simply as a basic expression ofevery human’s right to freedom of expression,unfiltered access to the Internet as a means

of communication with the world should be

Trang 27

protected Those who work to ensure thatright, both inside and outside of these

regimes, are freedom fighters and their workmust continue

Web Tools & Human Rights

Issues

Now that we understand how important thiswork truly is, it is helpful to see what tools aremost useful in the cause of Internet freedom

As mentioned above, one of the most

dramatic expressions of the Internet’s newrole in social and political activism is the ArabSpring Beginning in early 2011, a series ofdemonstrations and crackdowns in citiesacross the Middle East and Northern Africabegan an amazing series of domino-effectuprisings, leading to the downfall of regimes inEgypt, Libya, and Tunisia The effects are stillbeing felt, and at this moment the conflictrages on in Syria

Trang 28

The role that the Internet played in this is stillbeing hashed out, but (supposedly) one Cairoprotester put it this way: “We use Facebook

to schedule the protests, Twitter to

co-ordinate, and YouTube to tell the world.” TheInternet is a tool for communication, andcommunication is vital for organized

movements It’s as simple as that

Twitter, as a tool for immediate, widespreadcommunication, has obvious implications forfreedom of expression and protest Thedevelopers themselves openly value the role

of free expression not only for its politicalusefulness but for its role in daily life

From their blog:

Our goal is to instantly connect people

everywhere to what is most meaningful tothem For this to happen, freedom of

expression is essential Some tweets mayfacilitate positive change in a repressedcountry, some make us laugh, some make us

Trang 29

think, some downright anger a vast majority ofusers We don’t always agree with the thingspeople choose to tweet, but we keep theinformation flowing irrespective of any view

we may have about the content

Government entities have repeatedly

demanded Twitter censor or block certaintweets, and the company has been veryresistant to those efforts, but recent changeshave not been so freedom-friendly

In January of 2012, Twitter enabled a based system of tweet removal, so thattweets which have been deemed

nation-unacceptable by a certain country’s regimecan be removed from that country’s twitter-sphere This replaces a system where suchtweets would disappear completely, for users

in all countries The French organization

“Reporters Without Borders,” which is astrong defender of free speech around theworld, has come out publicly against this

Trang 30

change Others have been more positive.Paul Smalera, deputy Opinion Editor forReuters, wrote:

Twitter’s policy and its transparency pledgewith the censorship watchdog Chilling Effects

is the most thoughtful, honest and realisticpolicy to come out of a technology company

in a long time Even an unsympathetic reading

of the new censorship policy bears that out.Whatever side one comes down on, however,Twitter is clearly playing a major role in theInternet-freedom discussion

Another battlefield for Internet freedom is themajor search engines Google’s conflicts withthe Chinese government are widely publicized.The biggest exchange came in 2010, whenGoogle identified Chinese-backed hackers asthe culprits in a series of attacks that year.This led Google to end its previous policy ofself-censorship in accordance with the

Chinese government’s wishes, and directing

Trang 31

searches from within China to its uncensoredHong Kong based search portal,

Google.com.hk Since that time, Google hashad no presence in mainland China, and therehave been continued attacks from China-based hackers

Trang 32

Microsoft Bing has had its own problems withChinese influence on its searches, though in adifferent direction Bing has partnered withChina’s leading search Engine, Baidu, giving it

a huge step up over Google in the enormousChinese market The cost, though, might havebeen high:

Microsoft respects and follows laws andregulations in every country where we run

Trang 33

business We operate in China in a mannerthat both respects local authority and cultureand makes clear that we have differences ofopinion with official content managementpolicies.

In other words, Microsoft will censor whatChina wants to censor, but not like it This isnot the only time Microsoft has had issueswith Chinese censorship In 2009, not longafter MS first started dealing with Baidu andsearches in China, many people noticed thatwhenever one used Bing in the Chineselanguage, regardless of location, “sensitive”topics like the Dalai Lama, Tiananmen

Square, and human rights issues in China,were all censored At the time, Microsoftclaimed this was a bug, but subsequently itbecame clear that this was an inevitable part

of searching in Chinese Either way, it seemssomewhat fishy

Tools For Bypassing Internet

Trang 34

Besides the more obvious Internet tools, such

as search engines and social networks, freespeech on the Internet is also growing moredependent on tools that protect privacy andbypass some of the more pernicious elements

Apart from the kind of dissidents and activistswe’ve already discussed, Tor claims users inthe intelligence field, journalism, corporatesecurity and (of course) private users Tor’sprivacy protection is not perfect; on their ownwebsite, they say:

Tor can’t solve all anonymity problems It

Trang 35

focuses only on protecting the transport ofdata You need to use protocol specific

support software if you don’t want the sitesyou visit to see your identifying information.For example, you can use Torbutton whilebrowsing the web to withhold some

information about your computer’s

configuration [ ]Be aware that, like all

anonymizing networks that are fast enough forweb browsing, Tor does not provide

protection against endto-end timing attacks: Ifyour attacker can watch the traffic coming out

of your computer, and also the traffic arriving

at your chosen destination, he can use

statistical analysis to discover that they arepart of the same circuit

Tor itself is perhaps too visible, as now manyelements of its software are specifically

blocked in China, and Iran is targeting it aswell Tor’s developers are dedicated to

keeping up with the technology, though, andare developing new ways to help those under

Trang 36

harsh restrictions to communicate freely.Other services with a similar function exist, ofcourse, as well as more devious ways tobypass net filtering It’s a constant game ofwhack-a-mole for those in charge of blockingusers from the net, and those exploiting gaps

to help people get past the walls

Services called VPNs (Virtual Private

Networks) allow users in blocked countries to

“tunnel” into an external ISP, meaning thattheir web experience is basically that ofsomeone outside their borders VPNs require

a friendly server on the outside to run yourInternet through They also tend to be slow,but for people hungry for censored

information and desperate to have their voiceheard speed is probably not the biggestworry

These networks are also frequently used bymultinational corporations to connect

networks across national boundaries,

Trang 37

sometimes leaving a kind of backdoor foremployees of a company in, say, China, toaccess a network hosted in another countrywith less restrictions However, China hasbeen targeting VPNs Last year the Chinesegovernment started monitoring and restrictingtraffic over routers connecting to foreignnetworks to better prevent misuse of VPNs.Popular commercial VPN services includeTunnelbear (http://www.tunnelbear.com) andStrong (http://strongvpn.com/) but these may

be inaccessible from within strongly filteredweb infrastructures; China has preemptivelyprevented Tunnelbear from working insideChina, for example Strong VPN offers a freeversion called Open VPN, and according totheir website

Usually Open VPN will work in places wherePPTP VPN is blocked Places we have seenPPTP VPN blocked are locations in theMiddle East like Oman, Dubai and UAE

Trang 38

That’s not to say our PPTP VPN accountswon’t work there, some customers report noproblems It depends on your ISP usually, andyour local network.

These tools are just a couple of the resourcesavailable to help open access beyond closedborders on the Internet, and hopefully protectthe identities of their users in the process.The information above is all found on theInternet I could get it freely,

Trang 39

with no worries about governmental blocking

or visits by secret police

in the middle of the night I can criticize mygovernment, I can demand improvements inhuman rights, and I can do it without trying tohide Someday, I hope the same can be truefor all

For more information about issues of freedom

of speech and the open Internet, I highlyrecommend you visit the Electronic FrontierFoundation website and the OpenNet

Initiative These organizations are at theforefront of the fight for an open Internet forall Reporters Without Borders is another veryimportant organization, which focuses onfreedom of speech both on the net and off
