I have a couple of questions that are related to security.

Correct me if i'm wrong :)

  1. If I want to request something (ex: visiting www.google.com):

    • my computer will request that
    • then it will go to the ISP
    • then my ISP proxy server that will take the request and act as a middle man in this situation
    • ask for the site (www.google.com) and retrieve it
    • then the proxy will send it back to me

    I know that it's being done like that. So my question is: In this situation my ISP knows what I requested, and the proxy server is set by default (when I ask for an internet subscription).

    So, if I use another proxy (lets assume that is a highly anonymous and my ISP can't detect my IP address from it), would I visit my ISP and then from my ISP it will redirect me to the new proxy server that I provide?

    Will it know that there is someone using another proxy? Or will it go to another network rather than my ISP?

  2. This question is related to the first one.

    When I use a VPN, I know that VPN provides for me tunneling, encryption and many more features that a proxy can't. So my data is travelling securely and my ISP can't know what I'm doing. But my questions are:

    1. From where is the tunneling started? Does it start after I visit the ISP network (since they are the one that are responsible for forwarding my data and requests)?
      If so, then not all my connection is tunneled in this way, there is a part that is not being tunneled. Since, every time I need to do anything I have to go to my ISP and ask to do that. Correct me if I misunderstand this.
  3. I know that VPN can let my computer be virtually in another place and access its resources (ex: be like in my office while I'm in my home. This is done via VPN).

    1. If I use a VPN service provider so that I can access the Internet securely and without being monitored by my ISP, where is my encrypted data saved? Is it saved in my ISP or in the VPN service provider?

    2. If I use a VPN, does anyone on the internet know what I'm doing or who I am? Even the VPN service provider? Can they know me? I think they should know the person that is using this VPN service, correct?

@OliverSalzburg the "questions" seem related ,it shows what he doesn't understand. I don't think they work so well separately. –  barlop Jun 8 '12 at 16:24

Using a secure VPN tunnel would allow your ISP to still see the traffic as it is coming from their servers. However with SSH VPN Tunnels, you're encrypting the traffic that would otherwise be following the configuration of the web server you're pulling data from.

At work, I privately browse websites through a SSH VPN Tunnel that I have configured at home. My initial request goes from my Computer > Work ISP > Home VPN Server > Home ISP > Website. Since I have a direct tunnel to my VPN server and communicate it through SSH, I've configured my web browser so that it will use a SOCK5 proxy on a loopback to the SSH Tunnel that I've established.

However, this may not keep you 100% secure. If my Domain Controller has group policies configured to monitor and log browser/firewall activities, then it could still produce a trail of visited sites.
