What is TMG ?

 

Microsoft Forefront Threat Management Gateway (Forefront TMG), formerly known as Microsoft Internet Security and Acceleration Server (ISA Server), is a network security and protection solution for Microsoft Windows, described by Microsoft as “enables businesses by allowing employees to safely and productively use the Internet for business without worrying about malware and other threats“.

 

Features

Microsoft Forefront TMG offers a set of features which include:

  1. Routing and remote access features: Microsoft Forefront TMG can act as a router, an Internet gateway, a virtual private network (VPN) server, a network address translation (NAT) server and a proxy server.
  2. Security features: Microsoft Forefront TMG is a firewall which can inspect network traffic (including web contents, secure web contents and emails) and filter out malwares, attempts to exploit security vulnerabilities and content that does not match a predefined security policy. In technical sense, Microsoft Forefront TMG offers application layer protection, stateful filtering, content filtering and anti-malware protection.
  3. Network performance features: Microsoft Forefront TMG can also improve network performance: It can compress web traffic to improve communication speed. It also offers web caching: It can cache frequently-accessed web contents so that users can access them faster from the local network cache. Microsoft Forefront TMG 2010 can also cache data received through Background Intelligent Transfer Service, such as updates of software published on Microsoft Update website.

Anonymous Browsing with TOR Windows 7

What is Tor?

Tor is free software and an open network that helps you defend against a form of network surveillance that threatens personal freedom and privacy, confidential business activities and relationships, and state security known as traffic analysis.

Why Anonymity Matters

Tor protects you by bouncing your communications around a distributed network of relays run by volunteers all around the world: it prevents somebody watching your Internet connection from learning what sites you visit, and it prevents the sites you visit from learning your physical location. Tor works with many of your existing applications, including web browsers, instant messaging clients, remote login, and other applications based on the TCP protocol.

Why we need tor

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.

Staying anonymous

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 Torbutton 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.

Configuring Windows 7 to browse with TOR:

1. Go to website of tor project; https://www.torproject.org/

2. Clik to Download stable TOR;

3. Click to open downloaded .exe file, to start the setup;

4. When install leave default “FULL” instalation;

5.  Open the new installed program “VIDALIA”  and click on “Start Tor”

In 10-15 second you will be connected to TOR;

6. If you have some problem with default TorButton, check this;

Go to https://www.torproject.org/torbutton/ and install the stable TorButton; Firefox 5.0!

7. When TorButton install is finish, restart Firefox an you’ll see the new TorButton;

8. Click to this new button and choose “Toggle Tor Status”;

The Tor is now enabled in your browser, you see the green color on the TorButton;

9. Now TOR is started, as you can see on step 5. and you enable the tor for your browser “Firefox” with TorButton.

Now you can start your browsing through the internet and change your identity bi clicking “Use a New Identity” to change your IP address.

Every time you click on “Use a New Identity” you will get the different IP Address in Firefox, if  TOR is enabled.

If you want to test your IP Address, go to http://www.whatismyip.com/ and you will see, what is your current IP Address when you browsing through the internet with your Firefox Browser.
