Review :TOR BROWSER for internet SECURITY and PRIVACY
As the number of internet users continues to grow rapidly the need to secure our activities on the web becomes essentials. The internet has so evolved that it has become your first point of call in search of your missing cat.
Since the advent of online mall, internet banking, etc. A lot of people tend to do most of their transactions, 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 a track or hacked by internet experts.
For years the search for the best internet security bots has continued 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 lawyers? 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 surveying web sites without leaving government IP addresses in their weblogs, 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 traveling 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 support. 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 configuration.
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.
