Hello.  I am a newbie to the Linux world and I am anxious to see what all the hype is about in Linux.  I was just wondering what was the significance of the auth.log file in the Linux system? (I'm using Debian distro..just an fyi)

what purpose does the auth.log file serve in the linux system?

The Linux operating system, in all its flavors, has its own share of security flaws that allow intrusions, but there are various mechanisms by which these flaws can be removed, generally divided into two parts: authentication and access control. Authentication is responsible for ensuring that a user requesting access to the system is really the user with the account, while access control is responsible for controlling which resources each account has access to and what kind of access is permitted.
