Security and Threat Detection There are between 80 to 120 viruses reported till date in Unix. Threat detection and solution is very fast, as Linux is mainly community driven and whenever any Linux user posts any kind of threat, several developers start working on it from different parts of the world.

Open Source One of the main advantages of Linux is that it is an open source operating system i.e. its source code is easily available for everyone. Anyone capable of coding can contribute, modify, enhance and distribute the code to anyone and for any purpose.

The advantage over operating systems such as Windows is that security flaws are caught before they become an issue for the public. Because Linux does not dominate the market like Windows, there are some disadvantages to using the operating system. First, it's more difficult to find applications to support your needs.

The main difference between GNU and Linux is that GNU is an operating system designed as a replacement for UNIX with many software programs while Linux is an operating system with a combination of GNU software and Linux kernel. ... Linux is the combination of GNU software and Linux kernel.

Linux is just a kernel alone and uses various extra components from different sources. But FreeBSD has a kernel along with its own operating system that acts as a single-package unit. Even though this difference may look smaller, but it affects the way you interact and manages the system.

The main difference between kernel and shell is that the kernel is the core of the operating system that controls all the tasks of the system while the shell is the interface that allows the users to communicate with the kernel. Unix is an operating system. It is the interface between the user and the hardware.

“Linux is the most secure OS, as its source is open. Anyone can review it and make sure there are no bugs or back doors.” Wilkinson elaborates that “Linux and Unix-based operating systems have less exploitable security flaws known to the information security world.

Unix is a complete operating system on the other hand Linux is just a kernel. Users : Linux is used by everyone, from home users to developers and computer enthusiasts alike while Unix is mainly for mainframes, except OSK, which is developed for everyone.
