Why is Linux more secure than other operating systems?
Operating systems need no introduction these days. They are the software that plays the role of a manager that handles all the hardware attached to a computer. In general, an operating system is comprised of several components such as a boot loader, the kernel, daemons, the desktop environment, and applications. Generally, an operating system is deployed in any system where there is a need for multi-tasking. Also, there is a need for interfaces that allow the user to interact with the system and its applications.
Nowadays, an operating system is expected to appear with a GUI interface that allows the users to enjoy a best-in-class user experience while using the system.
What is Linux?
Linux is the free, open-source software operating system distribution that is built around the Linux kernel. Initially, it was developed for personal computers, which are now available in different versions for different types of users. Its popular distributions include Ubuntu, SUSE, CentOS, etc.
What is the relationship between Linux and security?
When we talk about any operating system or software that is open to the public for use, it comes under the threat of security. Every other user wants to know about the security features that the particular software or application offers. Linux systems are widely known for their security parameters. They rarely get infected by any viruses or malware. In general, it had never been seen that Linux attempted to sell anti-virus software to combat viruses. Instead, Linux is more secure than other operating systems.

Why is Linux more secure than other operating systems?
It takes into account the privileges; Linux has clearly stated the privileges wherein restricted access is clearly defined. Under this, root level access is assigned to the main users, which cannot be compromised in any case. In the event that the Linux system is used by another user, the root system will not be able to face any damage because of any virus. Only the files and programs may be affected.
Open-source but secure: Linux is open-source software and it is designed and maintained by highly qualified people. It was developed by many people, keeping in mind the security factor. Linux is developed using a highly process-oriented and engineered process. The whole source code behind Linux is maintained by subsystem maintainers, in which each and every change is reviewed thoroughly. Thus, it is secured by design also.
Memory management: Memory access and management are important parts of an operating system’s security. Every operating system works on different memory management models. In most operating system memory management models, user space and kernel space are not separated. When physical memory is available for the users to access, it directly comes into contact with malware and viruses. This is not the case with Linux. Here, user space and kernel space are separated. Thus, users who are using physical space for usage cannot access the virtual space. Thereby, the risk associated with malware and viruses decreases to a great extent.
With Linux, security is much watched by the experts and the community, and special care is taken in order to keep the system safe.
