If you go by software makers, Microsoft is unsurprisingly top of the rankings given the breadth of widely-used products it makes (not just Windows, but Office, web browsers and more). Some of the most critical vulnerabilities were found in Microsoft Office, too, with the report giving the productivity suite’s various security flaws a weighted average of 9.1 in terms of their seriousness.
That was beaten only by Adobe Flash Player (9.4) and Adobe Acrobat (9.2).
As for the type of vulnerabilities found, in 2019, a quarter (25.3%) 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%, followed by buffer overflows at 13.9%, and then denial of service attacks at 10.2%.
Mac computers have long enjoyed a reputation for being essentially immune to viruses and other types of malware. However, while they are still much more secure than Windows systems, Apple Macs are still vulnerable to some viruses and other malware, and it’s a growing problem. Apple’s built-in security system does a reasonable job at keeping malware at bay, but you should still consider beefing up protection by installing antivirus software.
Even if you’re just using a Mac as a home computer, there are some good reasons to consider improving security:
Mac’s operating system does come with built-in malware detection. This built-in detection feature is a nice-to-have, but with more threats, there’s an increased likelihood that new malware could find its way onto your system before Apple updates its databases. These are referred to as zero-day threats, and are reason enough to consider installing some security software.
While no single operating system is entirely secure, Linux is known to be much more reliable than Windows or any operating system. The reason behind this is not the security of Linux itself but the minority of viruses and malware that exist for the operating system.
Viruses and malware are incredibly rare in Linux. They do exist though the likelihood of getting a virus on your Linux OS is very low. Linux based operating systems also have additional security patches that are updated regularly to keep it safer.
The userbase of Linux is tiny when compared to Windows. While Operating systems like Windows and Mac house all kinds of users, Linux is inclined more towards advanced users. In the end, It all comes down to the caution taken by the user.
Yes, before you assume anything, viruses and malware can affect any operating system.
No operating system is 100% safe, and it’s a fool errand to look for one. Like Windows and Mac OS, you can get viruses on Linux. However rare they are, they still exist.
On the official page of Ubuntu, a Linux based OS, it is said that Ubuntu is highly secure. A lot of people installed Ubuntu for the sole purpose of having a dependable OS when it comes to the security of their data and sensitive details.
One more thing to ponder upon is the fact that Linux servers can get hit by malware just like any other server. The desktop version of Linux is highly safe, but the servers can get infected if infected files hit them. This is a simple case that can be fixed very easily in Linux.
Antivirus is not necessary on Linux based operating systems, but a few people still recommend to add an extra layer of protection.
Again on the official page of Ubuntu, they claim that you don’t need to use antivirus software on it because viruses are rare, and Linux is inherently more secure.
Linux still requires the user to take care of his work and sensitive details.
Still, when it comes to daily use, it is the only operating system out there right now that doesn’t require an antivirus software to function without any substantial risk.
