Why doesn’t Linux need an antivirus? This is the answer – There is a common myth among computer users and Internet users in general that they say that a Linux system cannot catch viruses. Of course this myth is not entirely true. Because computers with the Linux operating system can actually get viruses, but the myth that Linux can’t get viruses is also not 100% false. Because this myth has its basis, and most Linux systems really don’t need an antivirus.
Permission or Permission
The first bit of information you will need comes from the history of Linux. Linux is based on an old operating system called Unix. Unix started in the 1970’s at Bell Labs, but quickly gained popularity and spread to business and academic institutions around the world and this operating system is very popular among Indonesian users. Linux was originally an attempt to remake Minix, a variation of Unix. As a result, it inherits many properties from Unix, including its user permissions. On Unix systems, there is a clear distinction between user and administrator accounts. Users can’t install system-wide programs, and they don’t have access to important system folders. If you download and run a virus or any kind of malware on Linux, it can only clutter up your user account and the folders your user account has access to. It cannot spread and infect the entire system unless you somehow grant it administrator privileges. It is much more difficult for viruses to do damage to Linux computers.
In case you were wondering, MacOS is also a descendant of Unix, and has a similar permission system. So, this factor is also a common reason why Mac OS gets infected with viruses less frequently than Windows PCs.
Linux is not a big enough target for desktop users
Put yourself in the shoes of a hacker. Are you going to spend a lot of time developing malware for an operating system that only holds about 2-3% of the desktop linux user market? You’re better off getting your rogue virus to run on the operating system that takes up the most of the desktop space, and it’s still on the Windows OS. Because Linux is not as popular as Windows, this is the first reason why Linux doesn’t need an antivirus.
There is another interesting part here. Most malware preys on people who are not technically savvy. It’s sad, but it’s a lot easier to fool someone who doesn’t know what’s going on by clicking on that suspicious link or opening an obscure ZIP file. Most Linux users have at least a basic understanding of how computers work. After all, they choose to install Linux on their computers, of course they have at least some computer science knowledge. Again, considering the odds, hackers will have a better chance of attacking Windows users who, on average, are just computer users but don’t have a deep understanding of computer science.
Note that the above only pertains to desktop computers. For server computers of course this is a completely different story. In fact, Linux is the biggest target for server systems because it holds the majority of the market and most of the big businesses and major web hosting sites run on Linux systems. If your Linux server doesn’t have adequate and robust security, you may be in serious trouble.
Open Source Fixes Bugs Quickly
Many viruses and other types of attacks in cyberspace rely on known bugs and vulnerabilities in software on computers. If an attacker or hacker finds out that something isn’t functioning safely, they can exploit it to gain access to something they shouldn’t have. That’s how malware gets control in most situations.
Even though companies like Microsoft have grown better over the years at patching their software or software and fixing their bugs in a timely manner, the open source world is usually still faster. It’s not that Microsoft or any company was intentionally negligent; they have very few people looking at their source code. Unlike the open source code (open source) which can be reviewed by anyone. That means that every programmer around the world can see it, and if something goes wrong, they can send a fix to the developer. Even users without a technology background can help. If your Linux system isn’t working properly, you can reach out to the developer and let them know. They are usually quick to check and fix it.
When is Linux at risk?
As I explained above that the linux operating system can be infected with viruses, therefore always be careful and vigilant. And the following are some of the situations where Linux is really at risk of being attacked or infected with malware. In this situation, you really need to be aware of the configuration and security of your Linux system. Otherwise, dangerous things might happen to your linux.
Most of the web runs on Linux. It makes sense since Linux systems are known for their stability. They also make great platforms for many programming language open source that supports the web, such as PHP.
Thousands of websites are run on hosting service together or shared hosting which is not configured properly and there are many hosting users using un-updated versions of web programs, such as WordPress. Even worse, because of their nature as web servers, they can be accessed from anywhere by anyone. The hackers know this, and launch countless automatic attacks on Linux server every day.
If you are hosting a website or configuring a server for just about anything, take the necessary steps to ensure that you are following all the best practices for the security of your web server.
Web and Browser Attacks
A web browser is not just a browser. It may sound confusing, but when you think about all the things that need to be done best browser In order for you to be able to access and interact with your favorite sites, it is quite clear that there is a lot going on behind the browser.
Web based attacks are the main reason you need to configure your browser for security. You also need to use your mind when browsing the Web. Avoid URLs that look suspicious. Don’t click on the shortened URL unless you trust the source. If possible, stick to a service-secured site SSL (HTTPS).
What Can You Do to Protect Linux?
Even though there are many thoughts that Linux doesn’t need an antivirus, there are still antivirus software for linux although you won’t find as many antivirus programs as in general for Linux. If you are not sure that linux is really safe and running the system properly, after the Linux system is compromised, then using an antivirus for linux you can do for protection. Instead, you’ll find ways to prevent something from happening in the first place and ways to find out if something is wrong.
Block Ads and Online Scripts
On Linux desktops and laptops, your biggest threat comes from the Web. Luckily, it’s easy enough to block a lot of junk on the Internet. First, install a reputable ad blocker. While a site may be completely safe, the advertisements on it may not be. If you need any other reason to hate ads, they can actually give your computer a virus. You can try uBlock Origin on Firefox and Google Chrome. This is a great lightweight option that blocks almost anything to do with ads.
Malware on Linux systems is commonly referred to as a rootkit. That’s because it gets root, or administrator, privileges on the system. In most situations, if you have a rootkit, you will need to format your drive and start reinstalling from scratch. That’s why the available software checks for known rootkits, but makes no effort to remove them.
There are two popular options, chkrootkit and rkhunter, which are available for most Linux distributions. You can run it to try to see if the system has been compromised. But be careful. Both of them are known for giving false positive reviews. If you will be working with any of these software, always be careful to search and check your results for verification.
It’s also important to remember that rootkits are more likely to give you some other indication that they are there. Mysterious network activity coming from your computer is usually a rootkit entrance. You can use software such as Wireshark to see what traffic is passing through your computer.
Although Linux systems can be infected with malware, it’s still very rare on desktops / laptops and that’s the reason why Linux doesn’t need an antivirus. However, to avoid viruses on linux, always be vigilant when downloading, installing and running software. Block ads and scripts from untrusted websites, and generally use the best possible way to run your computer, and you will probably be just fine.
