While picking out an OS, one must consider an array of things. Among those, security is a vital factor in the present era. Every day, we read about incidents of cyber attacks and data breaches happening across the globe. In order to combat such attacks, one must have a robust and secure Operating System.
Linux is usually lauded is impervious to infections. To all intents and purposes, any device which is connected to a network is vulnerable to infections and cyber attacks, irrespective of its OS. However, far from Windows Operating System, Linux has not dealt with as many malware, worms, rootkits, etc. For this reason, people generally believe that Linux is immune to cyber attacks.
If you want to know what makes Linux the most secure and safest operating system, then read on.
1- Restricted Account Privileges
Linux systems are not perfect, not by a long chalk. However one of their chief strengths rests in how the account privileges are authorized. With Windows, users are usually granted admin access by default. Therefore users have access to all that is there on the system, even its most critical files, and folders. This way, when a hacker gets unauthorized access to the system, they can access everything that the user account can. It is similar to inviting thieves to your housewarming party.
In Linux, however, users have limited access. Therefore, if the system gets infected or hacked, there is not much damage that can be done. Hackers will not be able to access the entire system, and the malware will not be able to infect all the folders and files.
2- Tech-Savvy Users
Every other day, news concerning data thefts, hacking, and security breaches flash on our TV screens. Still, a number of Windows users do not even secure their systems with a password and fail to update their antivirus protection, if they have any that is. Linux users are more aware and conscious about security. They practice safe web surfing and are usually on their toes. In order to use Linux instead of Windows, one has to be a tad bit savvier. Therefore, the Linux community is usually more skilled and adept at preventing security threats.
3- IPtables Firewall
Iptables is a firewall based on a set of rules, which comes preinstalled with almost all the Linux Operating Systems. It directly controls all the incoming and outgoing traffic. People who face cyber attacks frequently, including brute force attacks, can simply block the IP addresses. If the attacks seem to originate from a particular destination, then the user can just block that entire country by adding the IP address to IPtables.
4- Fragmented Environment
The Unix environment is pretty vast. Some of the most popular Linux distributions are Debian, Fedora, Slackware, Arc Network, etc. Far from Window and Mac OS, both of which come from one distributor, Linux has a number of distros, and every one of them is unique. Users can customize a number of things. It’s not really a coherent OS, given that it lacks conformity and unity, it is very secure against malware. Because of the fragmentation, malware cannot spread as easily as on Windows or Mac.
