Exercise 1 - Maintain the Integrity of Filesystems

A Linux system stores everything in the form of a file. Everything includes data, drivers, and whatever other information on the system, which is not running as a process. These files are normally saved in a collapsible-tree structure. To maintain the integrity of the system, the system administrator ensures that the files are being saved as planned and that there are no unauthorized changes to the filesystem. Unauthorized changes can indicate a security compromise and might lead to data corruption.

In this exercise, you will understand how to maintain the integrity of filesystems.
