Four areas of concern for most computer users
When dealing with security, what we have to keep in mind is that an infected computer is almost always the users fault when it comes to Linux. At this time, Linux may be the most secure operating system available. There are a couple of reasons for this. First, the market share. Market share is really difficult to be accurate with. Some companies like Microsoft would like you to think that Windows is the only OS worth using. Quite the opposite is true. So for this article we'll say Windows has the largest share and then Apple & Linux. Keep in mind we are talking about desktop systems. Android which is Linux based has indisputably the largest share of the mobile device market. Being the largest share of the market makes Windows the biggest target for malware, viruses, Trojans, etc. Because of this, there are hardly any viruses in the wild that effect Linux. Viruses, malware, etc, are not generic. They must be created specifically for an operating system and its vulnerabilities. Therefore, viruses, malware, etc, created for windows will not affect your Linux system. Secondly, it's many times more difficult to create these malicious programs for Linux. Not impossible, just harder. And thirdly back door holes for hackers to get in are almost unheard of. For these reasons your Linux desktop does not need anti virus, malware, etc protection. The only programs available are scanners to keep your Linux computer free of Windows viruses, malware, etc. In short, you are helping protect Windows computers from themselves.
Linux is Open Source Software. Open source is exactly that. The source code is open to the public. Every person who uses one distribution or another of Linux has access to the source code to change it on their own computer, if they have the knowledge. What that means is that there are literally thousands and thousands of developers & skilled people constantly looking at the Linux source code. That does not mean that Linux is perfect. Just when bugs and glitches are found, they are mostly fixed before the new software ever reaches the public. And the few that reach the public are taken care of much quicker than those found in more popular OS's. This idea lends itself to a more stable system. Therefore, crashes, freezes, slow running computers, and any other erratic behavior are quite rare. Just a brief side note on a slow running computer: Windows 10 64bit requires a minimum of 2GB of RAM, recomended 4GB of RAM. Whereas Linux Mint 18, which is newer than Windows 10, has a requirement of 512 MB of RAM, recomended 1 GB of RAM. So Linux uses only 25% of the RAM that Windows uses for the same task. Our opinion on this would be that open source software such as Linux OS pushes more for quality, where as closed source software pushes for monetary return.
Linux updates consist of fixes, improvements, and additions to existing software packages. All of these come in the form of Security Updates, and Software Downloads. It is important to keep your Linux system up to date, which in turn keeps your Linux system secure. The great thing is this updating process is totally in your control. Updates are only installed when and if you choose, and only the ones that you choose. Updates are not automatic or out of your control. When you perform your updates your Linux Update Manager categorizes them in levels numbered 1, 2, 3, 4, & 5. By default Linux does not select levels 4 & 5. They should never be trusted. These usually come from third party sources and therefore can not be guaranteed to be safe. Level 3 updates are selected by default, but we recommend not installing them either, unless a particular update is needed. Levels 1 & 2 should always be installed. They can be trusted. By not installing levels 3 - 5 you are not missing any updates that you need.
As mentioned before The greatest thing about Linux is, that you are in control of your computer. You don't have a hardware company or a software company telling you what, where, when, or if you can do something on your computer. Then, after all of that, make you pay for all of those things you didn't ask for or want. Keep in mind we are talking about your computer that you bought with your money, and a company that does not own your computer telling you what to do with it and then charging you for that. Also, keep in mind, that there are proprietary software packages that are developed for Linux. These you may have to pay for and you may be limited on how you use them. Conclusion? Linux represents freedom of choice when it comes to computing.
