Supercodercylon Linux Operating System

An analysis of the National Institute of Standards and Technology’s National Vulnerability Database, compiled by Thebestvpn.com, tracked ‘technical vulnerabilities’ in popular pieces of software between 1999 and 2019.

Debian GNU/Linux is an open source Linux operating system build from scratch by a team of talented developers and hackers who wanted to create an alternative to existing Linux distributions, such as Slackware. Dubbed “The Universal Operating System,” Debian GNU/Linux is used as a base. If you're new to Linux, Jason Cannon's Linux for Beginners course is an excellent way to familiarize yourself with the operating system and command line. View Deal (Image credit: Nitrux).

  • SUSE, one of the three major enterprise Linux distribution companies, released on July 21, 2020, the next versions of its flagship operating system, SUSE Linux Enterprise (SLE) 15 Service Pack 2.
  • Just like Windows, iOS, and Mac OS, Linux is an operating system. In fact, one of the most popular platforms on the planet, Android, is powered by the Linux operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop.

The world’s worst was Debian, a flavour of Linux, top of the table with 3,067 vulnerabilities over the last two decades. Close behind was Android on 2,563 vulnerabilities, with the Linux kernel in third place having racked up a count of 2,357. Apple’s macOS was only slightly behind that with 2,212, with Ubuntu in fifth place on 2,007.

All of the top five places were taken by operating systems, although Firefox and Chrome filled the next two positions with 1,873 and 1,858 vulnerabilities respectively.

The Debian GNU Linux operating system, one of the oldest and influential Linux OSes Debian GNU/Linux is an open source Linux operating system build from scratch by a team of talented developers and hackers who wanted to create an alternative to existing Linux distributions, such as Slackware.

Microsoft’s Windows 7 bore 1,283 vulnerabilities, and Windows 10 carried 1,111. If you add those together, you get a total of 2,394 for the past decade.

Although note that some of the other figures mentioned represent a full two decades of existence – like Debian, which has been around since 1993 – so it’s difficult to make direct comparisons.

So when a Linux or Mac user tells you that their operating system is less buggy you can tell them to bog off with a pointy stick.

Looking at the figures for 2019 alone, Android was the most vulnerable piece of software with 414 reported vulnerabilities, followed by Debian Linux on 360, and Windows 10 was in third place in this case with 357.

The main problem with Microsoft’s image is that it is the most targeted by malware because there is more value in knocking over business systems.

As for the type of vulnerabilities found, in 2019, a quarter of all the observed security flaws were code execution vulnerabilities. Cross-site scripting was the second most prevalent gremlin in the works at 17.7 percent, followed by buffer overflows at 13.9 percent, and then denial of service attacks at 10.2 percent.

What is Linux?

LINUX is an operating system or a kernel distributed under an open-source license. Its functionality list is quite like UNIX. The kernel is a program at the heart of the Linux operating system that takes care of fundamental stuff, like letting hardware communicate with software.

Why do you need an OS?

Every time you switch on your computer, you see a screen where you can perform different activities like write, browse the internet or watch a video. What is it that makes the computer hardware work like that? How does the processor on your computer know that you are asking it to run a mp3 file?

Well, it is the operating system or the kernel which does this work. So, to work on your computer, you need an Operating System(OS). In fact, you are using one as you read this on your computer. Now, you may have used popular OS's like Windows, Apple OS X, but here we will learn introduction to Linux operating system, Linux overview and what benefits it offers over other OS choices.

Who created Linux?

Linux is an operating system or a kernel which germinated as an idea in the mind of young and bright Linus Torvalds when he was a computer science student. He used to work on the UNIX OS (proprietary software) and thought that it needed improvements.

However, when his suggestions were rejected by the designers of UNIX, he thought of launching an OS which will be receptive to changes, modifications suggested by its users.

The Lone Kernel & the early days

So Linus devised a Kernel named Linux in 1991. Though he would need programs like File Manager, Document Editors, Audio -Video programs to run on it. Something as you have a cone but no ice-cream on top.

As time passed by, he collaborated with other programmers in places like MIT and applications for Linux started to appear. So around 1991, a working Linux operating system with some applications was officially launched, and this was the start of one of the most loved and open-source OS options available today.

The earlier versions of Linux OS were not so user-friendly as they were in use by computer programmers and Linus Torvalds never had it in mind to commercialize his product.

This definitely curbed the Linux's popularity as other commercially oriented Operating System Windows got famous. Nonetheless, the open-source aspect of the Linux operating system made it more robust.

Linux gets its due attention

The main advantage of Linux was that programmers were able to use the Linux Kernel to design their own custom operating systems. With time, a new range of user-friendly OS's stormed the computer world. Now, Linux is one of the most popular and widely used Kernel, and it is the backbone of popular operating systems like Debian, Knoppix, Ubuntu, and Fedora. Nevertheless, the list does not end here as there are thousands of Best versions of Linux OS based on the Linux Kernel available which offer a variety of functions to the users.

Linux Kernel is normally used in combination of GNU project by Dr. Richard Stallman. All mordern distributions of Linux are actually distributions of Linux/GNU

The benefits of using Linux

Supercodercylon Linux Operating System Linux

Linux OS now enjoys popularity at its prime, and it's famous among programmers as well as regular computer users around the world. Its main benefits are -

It offers a free operating system. You do not have to shell hundreds of dollars to get the OS like Windows!

  • Being open-source, anyone with programming knowledge can modify it.
  • It is easy to learn Linux for beginners
  • The Linux operating systems now offer millions of programs/applications and Linux softwares to choose from, most of them are free!
  • Once you have Linux installed you no longer need an antivirus! Linux is a highly secure system. More so, there is a global development community constantly looking at ways to enhance its security. With each upgrade, the OS becomes more secure and robust
  • Linux freeware is the OS of choice for Server environments due to its stability and reliability (Mega-companies like Amazon, Facebook, and Google use Linux for their Servers). A Linux based server could run non-stop without a reboot for years on end.

Is it for me?

Users, who are new to Linux, usually shun it by falsely considering it as a difficult and technical OS to operate but, to state the truth, in the last few years Linux operating systems have become a lot more user-friendly than their counterparts like Windows, so trying them is the best way to know whether Linux suits you or not.

There are thousands of Best Linux OSs and Linux softwares available based on the Linux Kernel; most of them offer state-of-the-art security and applications, all of it for free!

This is what Linux is all about, and now we will move on to how to install Linux and which Distribution you should choose.

I am asked to Learn Unix? Then why Linux?

Supercodercylon linux operating system ubuntu

UNIX is called the mother of operating systems which laid out the foundation to Linux. Unix is designed mainly for mainframes and is in enterprises and universities. While Linux is fast becoming a household name for computer users, developers, and server environment. You may have to pay for a Unix kernel while in Linux it is free.

But, the commands used on both the operating systems are usually the same. There is not much difference between UNIX and Linux. Though they might seem different, at the core, they are essentially the same. Since Linux is a clone of UNIX. So learning one is same as learning another.
