The /etc/shadow file is used to store the information about user accounts that is critical to the security of those accounts, such as the hashed password and other security information.
Rationale:
If attackers can gain read access to the /etc/shadow file, they can easily run a password cracking program against the hashed password to break it. Other security information that is stored in the /etc/shadow file (such as expiration) could also be useful to subvert the user accounts.
Fix:
Run the following commands to set permissions on /etc/shadow- : # chown root:root /etc/shadow- # chmod u-x,go-rwx /etc/shadow-
Parameter:
[110000000, 42, 0]
Technical Mechanism:
Run the following commands to set permissions on /etc/shadow- : # chown root:root /etc/shadow- # chmod u-x,go-rwx /etc/shadow-
