<h1><a href="http://tor.eff.org/">Tor</a> documentation</h1>
|
|
|
|
<p>Tor provides a distributed network of servers ("onion routers"). Users
|
|
bounce their communications (web requests, IM, IRC, SSH, etc.) around
|
|
the routers. This makes it hard for recipients, observers, and even the
|
|
onion routers themselves to track the source of the stream.</p>
|
|

|
|
<h2>Why should I use Tor?</h2>
|
|
|
|
<p>Individuals need Tor for privacy:
|
|
<ul>
|
|
<li>Privacy in web browsing -- both from the remote website (so it can't
|
|
track and sell your behavior), and similarly from your local ISP.
|
|
<li>Safety in web browsing: if your local government doesn't approve
|
|
of its citizens visiting certain websites, they may monitor the sites
|
|
and put readers on a list of suspicious persons.
|
|
<li>Circumvention of local censorship: connect to resources (news
|
|
sites, instant messaging, etc.) that are restricted from your
|
|
ISP/school/company/government.
|
|
<li>Socially sensitive communication: chat rooms and web forums for
|
|
rape and abuse survivors, or people with illnesses.
|
|
</ul>
|
|
|
|
<p>Journalists and NGOs need Tor for safety:
|
|
<ul>
|
|
<li>Allowing dissidents and whistleblowers to communicate more safely.
|
|
<li>Censorship-resistant publication, such as making available your
|
|
home-made movie anonymously via a Tor <a
|
|
href="http://tor.eff.org/doc/tor-hidden-service.html">hidden
|
|
service</a>; and reading, e.g. of news sites not permitted in some
|
|
countries.
|
|
<li>Allowing your workers to check back with your home website while
|
|
they're in a foreign country, without notifying everybody nearby that
|
|
they're working with your organization.
|
|
</ul>
|
|
|
|
<p>Companies need Tor for business security:
|
|
<ul>
|
|
<li>Competitive analysis: browse the competition's website safely.
|
|
<li>Protecting collaborations of sensitive business units or partners.
|
|
<li>Protecting procurement suppliers or patterns.
|
|
<li>Putting the "P" back in "VPN": traditional VPNs reveal the exact
|
|
amount and frequency of communication. Which locations have employees
|
|
working late? Which locations have employees consulting job-hunting
|
|
websites? Which research groups are communicating with your company's
|
|
patent lawyers?
|
|
</ul>
|
|
|
|
<p>Governments need Tor for traffic-analysis-resistant communication:
|
|
<ul>
|
|
<li>Open source intelligence gathering (hiding individual analysts is
|
|
not enough -- the organization itself may be sensitive).
|
|
<li>Defense in depth on open <em>and classified</em> networks -- networks
|
|
with a million users (even if they're all cleared) can't be made safe just
|
|
by hardening them to external threat.
|
|
<li>Dynamic and semi-trusted international coalitions: the network can
|
|
be shared without revealing the existence or amount of communication
|
|
between all parties.
|
|
<li>Networks partially under known hostile control: to block
|
|
communications, the enemy must take down the whole network.
|
|
<li>Politically sensitive negotiations.
|
|
<li>Road warriors.
|
|
<li>Protecting procurement patterns.
|
|
<li>Anonymous tips.
|
|
</ul>
|
|
|
|
<p>Law enforcement needs Tor for safety:
|
|
<ul>
|
|
<li>Allowing anonymous tips or crime reporting
|
|
<li>Allowing agents to observe websites without notifying them that
|
|
they're being observed (or, more broadly, without having it be an
|
|
official visit from law enforcement).
|
|
<li>Surveillance and honeypots (sting operations)
|
|
</ul>
|
|
|
|
<p>Does the idea of sharing the Tor network with
|
|
all of these groups bother you? It shouldn't -- <a
|
|
href="http://freehaven.net/doc/fc03/econymics.pdf">you need them for
|
|
your security</a>.</p>
