Review :TOR BROWSER for internet SECURITY and PRIVACY

Published by kelvin Ehiozefe on

Today as the number of internet user
continue to grow rapidly the need to secure our activities on the web becomes
essentials. The internet has so evolve that it has become your first point of
call in search of your missing cat.
Since the introduction of online mall, internet banking, etc. A lot of people tend to do most of their transaction, shopping via the internet unconsciously exposing details of
their credit card or any other vital credential on the internet for hackers. Hence, in a way to cub this threat of been hacked i  decided to share with you a secure and better way of surfing the net and avoid been track or
hacked by internet expert.
For years the search for the best
internet security bots has continue to spread among internet surfers but since
the introduction of the TOR BROWSER the search internet security bots may fade
out soon.
The Tor network is a group of volunteer-operated
servers that allows people to improve their privacy and security on the
Internet. Tor’s users employ this network by connecting through a series of
virtual tunnels rather than making a direct connection, thus allowing both
organizations and individuals to share information over public networks without
compromising their privacy. Along the same line, Tor is an effective censorship
circumvention tool, allowing its users to reach otherwise blocked destinations
or content. Tor can also be used as a building block for software developers to
create new communication tools with built-in privacy features.
Who is Tor Browser made for?
Individuals use Tor to keep websites
from tracking them and their family members, or to connect to news sites,
instant messaging services, or the like when these are blocked by their local
Internet providers.
Journalists use Tor to communicate
more safely with whistleblowers and dissidents. Non-governmental organizations
(NGOs) use Tor to allow their workers to connect to their home website while
they’re in a foreign country, without notifying everybody nearby that they’re
working with that organization.
Who is recommending TOR for use?
Groups such as Indymedia recommend
Tor for safeguarding their members’ online privacy and security. Activist
groups like the Electronic Frontier Foundation (EFF) recommend Tor as a
mechanism for maintaining civil liberties online. Corporations use Tor as a
safe way to conduct competitive analysis, and to protect sensitive procurement
patterns from eavesdroppers. They also use it to replace traditional VPNs,
which reveal the exact amount and timing of communication. Which locations have
employees working late? Which locations have employees consulting job-hunting
websites? Which research divisions are communicating with the company’s patent
A branch of the U.S. Navy uses Tor
for open source intelligence gathering, and one of its teams used Tor while
deployed in the Middle East recently. Law enforcement uses Tor for visiting or
surveilling web sites without leaving government IP addresses in their web
logs, and for security during sting operations.
The variety of people who use Tor is
actually part of what makes it so secure. Tor hides you among the other users on the network, so the more populous and diverse the user base for Tor is,
the more your anonymity will be protected.
Using Tor protects you against a
common form of Internet surveillance known as “traffic analysis.”
Traffic analysis can be used to infer who is talking to whom over a public
network. Knowing the source and destination of your Internet traffic allows
others to track your behavior and interests. This can impact your checkbook if,
for example, an e-commerce site uses price discrimination based on your country
or institution of origin. It can even threaten your job and physical safety by
revealing who and where you are. For example, if you’re travelling abroad and
you connect to your employer’s computers to check or send mail, you can
inadvertently reveal your national origin and professional affiliation to
anyone observing the network, even if the connection is encrypted.
How does traffic analysis work?
Internet data packets have two parts: a data payload and a header used for
routing. The data payload is whatever is being sent, whether that’s an email
message, a web page, or an audio file. Even if you encrypt the data payload of
your communications, traffic analysis still reveals a great deal about what
you’re doing and, possibly, what you’re saying. That’s because it focuses on
the header, which discloses source, destination, size, timing, and so on.
A basic problem for the privacy
minded is that the recipient of your communications can see that you sent it by
looking at headers. So can authorized intermediaries like Internet service providers
and sometimes unauthorized intermediaries as well- A very simple form of
traffic analysis might involve sitting somewhere between sender and recipient
on the network, looking at headers.
But there are also more powerful kinds
of traffic analysis. Some attackers spy on multiple parts of the Internet and
use sophisticated statistical techniques to track the communications patterns
of many different organizations and individuals. Encryption does not help
against these attackers, since it only hides the content of Internet traffic,
not the headers.
How does TOR WORK?
Tor helps to reduce the risks of
both simple and sophisticated traffic analysis by distributing your
transactions over several places on the Internet, so no single point can link
you to your destination. The idea is similar to using a twisty, hard-to-follow
route in order to throw off somebody who is tailing you — and then periodically
erasing your footprints. Instead of taking a direct route from source to
destination, data packets on the Tor network take a random pathway through
several relays that cover your tracks so no observer at any single point can
tell where the data came from or where it’s going.
To create a private network pathway
with Tor, the user’s software or client incrementally builds a circuit of
encrypted connections through relays on the network. The circuit is extended
one hop at a time, and each relay along the way knows only which relay gave it
data and which relay it is giving data to. No individual relay ever knows the
complete path that a data packet has taken. The client negotiates a separate
set of encryption keys for each hop along the circuit to ensure that each hop
can’t trace these connections as they pass through.
Once a circuit has been established,
many kinds of data can be exchanged and several different sorts of software
applications can be deployed over the Tor network. Because each relay sees no
more than one hop in the circuit, neither an eavesdropper nor a compromised
relay can use traffic analysis to link the connection’s source and destination.
Tor only works for TCP streams and can be used by any application with SOCKS
For efficiency, the Tor software
uses the same circuit for connections that happen within the same ten minutes
or so. Later requests are given a new circuit, to keep people from linking your
earlier actions to the new ones.
Though Tor can’t solve all anonymity
problems, it focuses only on protecting the transport of data. You need to use
protocol-specific support software if you don’t want the sites you visit to see
your identifying information. For example, you can use Tor Browser
while browsing the web to withhold some information about your computer’s
Also, to protect your anonymity, be
smart. Don’t provide your name or other revealing information in web forms. Be
aware that, like all anonymizing networks that are fast enough for web
browsing, Tor does not provide protection against end-to-end timing attacks: If
your 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 are part of the same circuit.
What are the negative effects of using TOR?
Tor’s hidden services
let users publish web sites and other services without needing to reveal the
location of the site. Individuals also use Tor for socially sensitive
communication: chat rooms and web forums for rape and abuse survivors, or
people with illnesses.

facts about the TOR network; hence readers and followers of this blog are hereby
