What is the Ubuntu “built in virus protection”?
One question I get asked a lot is why there are no viruses on Ubuntu (Linux in general). Even though it is possible to infect it and a small amount of low level bugs have appeared, I wanted to point out the key elements that make it very tough for viruses and malware in general to infect Ubuntu as easy as in Windows, specially the 2 most common effects which are:
- The action of infecting a computer
- The action of propagating to other computers.
Using the common characteristics of a virus which are:
- Attaching/Modifying a file
- Attaching/Modifying a process
So why is it so difficult for a virus to infect Ubuntu?. Why is it so difficult to infect the most known parts of Ubuntu for example:
- The kernel
- Default packages
- PPA Packages
- Other packages (Website DEB Package, Source)
