What are some of the recommended techniques to audit our system?

[dimmetrix]

I open this question so that among all we believe in the most complete way the tools or commands to execute to check if our system or personal files and folders are being accessed by an unauthorized person (either from the internal or external network) .


Everyone talks about the security of Linux, but Linux is also vulnerable and even worse when it is in the hands of someone who does not know how to audit it to find out if everything works safely as it seems to work.
