. I Am learning sysadmin fundamentals but it is extremely hard. Please help!
Not that hard, once the idea of what is expected from a sysadm: Administering a UNIX environment with users, printers, server(s) and maybe workstations...
1. The problem statement, all variables and given/known data:
Set permissions on sensitive files:
I dealing with users: users have rights and permissions and UNIX permissions (basic) are limited to 3 cases:
the user/ownrt, a group owner, and the rest of the planet
Set permissions on /etc/shadow to allow only root read and write access.
Set permissions on /etc/gshadow to allow only root read and write access.
How do you think this can be done knowing the 3 cases?
I suggest you look at the man pages of your 3 commands ls, chown, chmod
I let you start now, Im off to physio and will look and complete once back

logindevperm, fbtab - login-based device permissions SYNOPSIS
/etc/logindevperm DESCRIPTION
The /etc/logindevperm file contains information that is used by login(1) and ttymon(1M) to change the owner, group, and permissions of devices upon logging into or out of a console device. By default, this file contains lines for the keyboard, mouse, audio, and frame buffer devices. The owner of the devices listed in /etc/logindevperm is set to the owner of the console by login(1). The group of the devices is set to the owner's group specified in /etc/passwd. The permissions are set as specified in /etc/logindevperm. Fields are separated by TAB and/or SPACE characters. Blank lines and comments can appear anywhere in the file; comments start with a hash- mark, ` # ', and continue to the end of the line. The first field specifies the name of a console device (for example, /dev/console). The second field specifies the permissions to which the devices in the device_list field (third field) will be set. These permissions must be expressed in octal format. For example, O774. A device_list is a colon-separated list of device names. Note that a device name must be a /dev link. A device entry that is a directory name and ends with "/*" specifies all entries in the directory (except "." and ".."). For example, "/dev/fbs/*" specifies all frame buffer devices. Once the devices are owned by the user, their permissions and ownership can be changed using chmod(1) and chown(1), as with any other user- owned file. Upon logout the owner and group of these devices will be reset by ttymon(1M) to owner root and root's group as specified in /etc/passwd (typically other). The permissions are set as specified in the /etc/logindevperm file. FILES
/etc/passwd File that contains user group information. SEE ALSO
chmod(1), chown(1), login(1), ttymon(1M), passwd(4) NOTES
/etc/logindevperm provides a superset of the functionality provided by /etc/fbtab in SunOS 4.x releases. SunOS 5.10 22 Oct 2003 logindevperm(4)
