Protect your Linux now and beyond

Linux-based operating systems are known for their high level of security. This is one of the reasons why Linux's market share has grown – but not at an impressive rate. According to statistics from the Berkeley Linux Users group. Here protect your Linux now and beyond.

The most commonly used operating systems, such as Windows 10, are often affected by targeted attacks in the form of ransomware infections, spyware, as well as worms and malware.

Linux-based systems are not targeted as often as other popular operating systems.

Not being targeted as often does not mean that they are totally foolproof. No system is. Due to all targeted attacks, many personal users, as well as companies, are turning to Linux-based operating systems.

Consider systems such as the Ubuntu-based Linux operating system. There are many risks and vulnerabilities for all types of Linux devices, which puts your privacy and identity at risk.

Improve your security:

Install a VPN

A Virtual Private Network (VPN) helps protect your Internet traffic from prying eyes. This includes malicious attackers who may control various routing devices between you and the resource you are trying to access.

VPN also prevents your Internet Service Provider (ISP) from recording your Internet activity and preventing your Wi-Fi provider from sneaking into your business. You can also use a VPN to access restricted content on YouTube, Netflix, Hulu, and more.

To choose a good VPN for Linux will bring you the maximum security and maximum performance when you take care of your business. A VPN allows you to hide the IP and location of your computer to prevent the logging of metadata and browsing activity from your ISP.

In addition, you can bypass Internet censorship and firewalls when using a VPN for Linux. You do not have to worry about your privacy and security online when using a VPN for Linux. It's easy; all you have to do is download a VPN client and log in.

Keep your system up-to-date

Keeping your operating system up-to-date is one of the most effective ways to protect your devices, no matter what operating system you use. However, this seemingly obvious task is also easy to overlook, especially if you do not understand the importance of keeping your system up to date.

In addition to your operating system, keep your applications such as video players, PDF readers, and Web browsers up-to-date. Most Linux-based operating systems allow users to keep their systems up to date very easily.

For example, Ubuntu automatically installs default security updates. Select System Settings> Software and Updates> Updates to check. Make sure all important updates are enabled. Tracking updates helps you make sure that there are no vulnerabilities that hackers can exploit to make their way into your system.

Enable your firewall

The role of a firewall is to block access to unsecured services on your computer. A few years ago, it was considered extremely risky to access the Internet without a firewall. Today, some operating systems such as Ubuntu, based on Linux, do not have a firewall enabled by default.

This is because Ubuntu does not have Internet services running on a standard installation, which makes a firewall unnecessary. Broadband routers, however, include a default firewall.

When it is Ubuntu, all it takes to compromise your security is to install something vulnerable or inadvertently mess up the configuration. If this happens, you will need a firewall. Fortunately, it is easy to install a firewall under Linux.

The Linux kernel has a default firewall feature, and all you have to do is add a graphical frontend. Ubuntu systems have a command-line utility called UFW. It is installed but not activated. You can use this utility to start the firewall and block all incoming connections.

Use an antivirus

Windows is the most common operating system. As a result, most malware is typically designed for Windows systems and is not enabled on your Linux devices. For this reason, some consider that the anti-virus is completely useless for Linux-based systems.

However, what most Linux users do not know is that there is a more sophisticated malware designed to attack the Linux operating system. The probability of such an attack is small, however.

However, there are arguments that the number of malware and viruses targeting Linux is increasing. Once they attack you, you have no way to defend yourself. It's always a good idea to stay protected, even against the least expected attacks.

After all, feeling safe simply because the risk of violation is low means that the attacker already has a length ahead of you. Use the Linux antivirus to be sure. There are many, find one that protects you best.

Encrypt your drive (Full Disk Encryption)

The most recent versions of the Linux distribution will ask you if you want to encrypt your drive during the installation process. Always make sure that you choose to encrypt your drive when you install Gnome, Kubuntu, BackTrack or any other type of Linux distribution to protect your data.

Your data remains 100% safe if encrypted, whether using a hard drive or SSD. Only you will be able to access the contents of the reader once you have chosen to encrypt it. When connecting, you will need to enter your password to decrypt the reader. The ability to encrypt your drive is very convenient when using a mobile device or laptop.

As long as your drive is encrypted, no one will be able to access your valuable data even if your laptop is stolen. In addition to full disk encryption, Linux also allows users to encrypt their home directory and create a fully protected system.

Do not run like a root for everything

One of the most notable differences between Windows and Linux is that standard user accounts can not destroy the integrity of the Linux system. On Linux, you can only do this using the system administrator.

You will need to use the root account for specific administrative tasks, but you must separate them from regular desktop management and daily monotony. You will need to enter your password for all administrative tasks when you do not run root. Many users find endless password requests tedious and use a root source (the same password in front of them – do not do it!) For everything.

It is a mistake. Do not be tempted to run as a root user (a password is pretty tricky, but it's not the case: a root is placed in front of the system's passwords) or any other item that might compromise the security of your device. It is likely that you will make an error that will eventually destroy the integrity of your system if you spend a lot of time as root.

Disable USB mount

When dealing with someone who can physically alter your computer, disabling the USB mount is a crucial method that you can use to ensure increased security. The only drawback is that you will have to find another way to transfer data safely once you have disabled USB editing on your Linux device.

However, the existence of sophisticated malware that activates automatically once the pen is inserted into your computer is worth it.

Use strong passwords

Last but not least, use strong passwords to secure your device. We have been advised repeatedly to use strong passwords to protect our personal data. However, most of us do not pay enough attention to passwords. Your password is the key to your entire online identity, not just a barrier to your office.

A password must be strong and unique. Use a combination of uppercase and lowercase letters, numbers, symbols, and other characters to create strong passwords for your Linux devices and online accounts.

Linux is one of the most secure operating systems on the market. Linux is not very interested in cybercriminals and only runs on about 2% of desktop computers in the world.

But being part of a small minority does not guarantee security. Linux malware exists and Linux devices are hacked, stolen or lost. Follow these tips to protect your Linux computer at all times.
