Linux-based operating systems are, in the opinion of specialists, extremely safe environments for users. For this reason, Linux runs on the most powerful computers in the world, on the vast majority of servers, on computers on the International Space Station, etc., being also in the service of various more or less secret institutions of the army. All this is happening to the detriment of Windows, the most used and most publicized operating system for a long time.

However, Linux is not invincible. No operating system of the present or the future can receive this label. Below we offer you some tips to be / feel more secure in the face of problems when using a GNU / Linux distribution. So, here's how you can improve security on Linux:

Install a famous distribution

Only install GNU / Linux distributions that are known and appreciated, especially if you are a beginner.

Be careful which version of the distribution you choose

It sounds like a joke, but there are enough people who, by mistake, install versions that are no longer supported by the community. The latest versions can always be found on the official distribution page.

Keep your operating system up to date

It is crucial that any operating system is up to date in terms of updates. Such a habit of checking if it is up to date should be formed and maintained as long as you use a computer.

Enable firewall

A tool without which security cannot be conceived, either on Windows or on GNU / Linux, is the firewall.

Install applications only from credible sources

Such a credible source is represented by Software Centers or application stores that you can find on almost all Linux distributions. Avoid downloading applications from other sites as much as possible.

Don't enter codes you don't understand

If you inevitably get to the terminal, try not to enter codes that you do not know what they do or that seem suspicious.

Do not log in as root

Do not log in as root for a long time but only as long as necessary.

Use an antivirus from time to time

There are also such programs for Linux and it wouldn't hurt to have one installed.

Disable guest account

Logically, I don't think you want anyone to have access to your computer unless you don't want to. The reasons are various.

Don't play with the password

The password must be known only to you and trusted people, it must contain complex characters and, in no case, we do not suggest you use any password generator.

Back up your data

From time to time do not hesitate to make a backup of the operating system that you can restore in the event of problems

Choose encryption of the main partition

This solution is available to you from the installation of the system and offers you an extra security.

Save your important data on USB sticks or external hard drives.

This is the best way to make sure no one has access to them.
