How to ensure the confidentiality of communication on the network?

Question

Encryption

Greetings.
On April 8, Minister Medvedev signed Decree No. 327 . As I understand it, now officially various departments can easily access almost any information:

... receiving, transmitting, delivering and (or)
processing voice information, written text, images,
sounds or other electronic messages ...

Now everything is "under close scrutiny", but this is personal information and only a few will want to share it even under the law and even with its crystal clearness.
What, now correspondence in viber, skype, telegram, gmail, etc. will be available to anyone from any department? One can imagine the work of such a department: some secretary wanted to read the confidential correspondence of a "friend" at her leisure, and in fact she really reads it.
How to ensure maximum confidentiality of communication on the network? Well, there is no desire to share with anyone. As if they are signing a decree that any official can easily open access to your computer and climb there, find something interesting, neigh with colleagues ..... smells like totalitarianism.

Answer 1

The main thing is not to use services from the Russian Federation, but only foreign ones, this applies to everything.
Generally everything.
Foreign providers are very jealous of the data of their users and just like that they will not give anything away, and will not show it, especially to some FSB officers from the Russian Federation.
At most, they will show it:
Forget about all sorts of FSB-shnye Yandex, vkontakte, one-eyed, telegrams and other slag.
And of course, if your router is from Rostelecom, Beeline, and other RF providers, then change it immediately.

Answer 6

Unfortunately, any defense will most likely cause you to take a closer look at you.
GPG is based on public key cryptography. Nothing but encrypted data is available to the operator. The main thing is to keep your keys protected.
If for business, then deploy your PKI and encrypt mail, files, etc.

Answer 7

the future belongs to decentralization, encryption and open source solutions

In addition to the article, I would like to mention one tool - retroshare - which provides almost all of the above at once, moreover, in a fairly digestible wrapper.
but all these means will require a change of habits, the rejection of the miserable Skype, the ancient email and other gills.
for supporters of the classics, you can limit yourself to adding encryption to already known applications, for example, pgp for mail.

Answer 8

The question is not whether there is something to hide or not. People have a constitutional right to freedom of communication, but here this right is going to be regulated.
If we are talking about corporate communication, then you just need to install a local corporate chat on your network and not use Skype, Viber and other public IM. The messenger server will be under your control, enable encryption and all business.
With regards to mail - turn on PGP and you will be calm.
Regarding the corporate site - HTTPS is everything.
