Description
This prevents attackers with physical access from trivially bypassing security on the machine and gaining root access. Such accesses are further prevented by configuring the bootloader password.
ℹ️ Check
Verify that the "root" account has a password assigned: # cut -d: -f1,2 /etc/passwd | grep root root:! If the "root" account is not listed with an "!", this is a finding.
✔️ Fix
Assign the "root" account a password using passwd command while logged on as "root": # passwd
