Tails - the most private operating system
Privacy and anonymity on the global internet are very fragile things. As soon as we visit certain websites, a considerable number of companies "spy" on this action. This results in at least targeted advertising, and at most - a digital profile of a citizen on the internet. Forgetting to turn on the VPN, or leaving a comment from the wrong account - all this is collected, stored, and can be exploited by an OSINT engineer (search specialist) or a hacker.
The same applies to a physical personal computer or laptop. A huge amount of logs, which sooner or later can be revealed by installed programs or source codes.
Fortunately, there are ways to protect against all of this. There is a rich list of various software ranging from anonymity on the network to cryptography within the hard drive. However, the complexity of self-installation takes away a valuable resource - time.
And it seems that one has to navigate between technical details (or trust all of this to specialists) and try to sleep peacefully. But there is a solution that can help even the most avid paranoid.
Attention
This solution was used by Edward Snowden when he was hiding from the NSA. And, in the end, he successfully concealed himself.
Tails is an operating system based on Linux OS. It is not installed on the hard drive but is booted from a removable device (USB flash drive). All information that needs to be worked with is loaded only into volatile RAM, which is energy-dependent. This means that after shutting down or rebooting the system, no logs or traces remain (browser history, logs of opened documents, temporary files).
