How can I know that my data is not being shared with others behind the scenes? This is a legitimate concern for many. Here I provide ideas and tools for how you can verify that your data is not being shared without your permission.

Some of them use a notebook computer that they keep locked in a safe to minimize the risk that someone will access the computer directly.


Configure a firewall to block all external connections.

Baring complete isolation from any networks, another approach might be to block all outbound connections from your computer to the outside world using a firewall. There are many ways to do this. Here is an example using Windows Firewall. Here is an example for Mac Computers. There are also many third-party tools for this.
