Benefits of Using Linux

The primary benefit of using Linux is security. You won't have a problem with viruses messing up your computer. In my long experience of using Linux, there was not a time where I had to reformat my computer because of a virus or trojan attack. Or because something messed up with my system registry. It does not mean that viruses won't find their way into your computer. It is just that they won't be able to carry out their malicious intent. They would find themselves stuck in the folder where they first land. And you can simply delete them when you notice them.

So how is this possible?
 
Linux Files and Folders Security Policies There are three kinds of user privelges in Linux.
 
a. Owner - is the person who created a file or folder.

b. Group - a person could belong to a group. The Group setting of a user allows them to have access to files and folders that have been created by another user who belongs to the same group.  

c. Root - This is the admin or superuser. They have access to everything.

There are three kinds of permission settings for each files and folders.

1. read access - Which means you can read but you can't edit them.

2. read/write access - which means they are editable.

3. read/execute - you can read and execute the file but you can't edit them.

4. read/write/execute - you can read, write, and run the file.

The Owner and the superuser can set the privileges available for a file or folder. They have the option to even limit the access of other users that belong in their group. Now if you are not the owner, not a superuser, and not a member of the group, that means you wont even see the file or folder at all. Linux systems files are also editable only by the root user. This is what makes Linux systems very secure. As long as you don't give your access to somebody else, you can be sure that your files and folders will be safe.
