[Aide] Which files to monitor?

[Sonixxfx]

Hi,

I would like to use Aide but I'm wondering which files I should
monitor on my Linux system. I know there are important files that
should be monitored like /etc/passwd for example, but I am wondering
how I should handle the other files. There are so many of them and
many are changed after each system update, so monitoring them would be
difficult, and everyone of them could contain malicious code.

So can someone explain to me how I should handle this?

Thanks for your help.

Regards,

Ben
