I have a couple of questions that are related to security.
Correct me if i'm wrong :)
If I want to request something (ex: visiting www.google.com):
my computer will request that
then it will to the ISP
then to 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 its being done like that. So, my question is that, in this situation my ISP knows everything and what I did request, and the proxy server is set by default (when I ask for an internet subscription).
So, if I use here 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? Because I didn't get the view clearly.
This question is related to the first one.
When I use a VPN, I know that VPN provides for me a tunneling, encryption and much 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:
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.
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).
If I use a VPN service provider so that I can access the internet securely and without being monitored by my ISP. In this case, where is my encrypted data saved? Is it saved in my ISP or in the VPN service provider?
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 asking for this VPN service, am I right?
