Linux Doesn’t Need An Antivirus Or Firewall

No, Linux Don't Need An Antivirus Or Firewall

First, let us see why Linux doesn’t need an antivirus or firewall. The following are some of the reasons behind the fact that an Antivirus is unnecessary on a Linux system:

It is not profitable to attack Linux:

Linux is one of the least popular desktop operating systems. Linux users are too tech-savvy, while the other operating systems contain certain flaws using which they can be attacked easily. Therefore, attacking the Linux operating system is not that profitable.

Linux malware is also out there, but it is not that very problem-causing as on the other operating systems. The chance of encountering a Linux malware is almost negligible.

The software installations on a Linux system are safer:

On Windows and Mac, system-level access is needed for installations. This situation is one of the major avenues for malware attacks.

Whereas on a Linux system, the installer files are unconventional. The users depend on package managers such as APT and YUM. So, encountering malware attacks on a Linux system is virtually zero. So, Linux doesn’t need an antivirus.

Linux Doesn’t Need An Antivirus

A Linux system can protect itself from malware:

If a Linux system contracts a Trojan or virus, which is highly unlikely, the virus will not be able to cause any damage to it. This is because of the manner in which permissions function in Linux.

In case a virus or any other malicious software infects a Linux system, it will be executed under your local account. The virus (or malicious software) will get trapped and restrained.

Therefore, you can be sure that your Linux system can safeguard itself from any kind of malicious software.

Now, let us look into the reason why Linux does not need a firewall.

A firewall is primarily used for allowing or disallowing the incoming connections. It is rare for a firewall to filter outgoing connections.

A firewall is not needed in the case of a Linux desktop user.

You will require a firewall only when you are trying to run a server application on your Linux system. In case you do not have any servers running on your Linux system, then it means that the system will not be listening for any incoming connections. This, in turn, indicates that nobody will be able to connect to the system.

So, we can say that a firewall is unnecessary in the case of any Linux system.

We have now discussed the reasons behind a Linux doesn’t need an antivirus or a firewall.
