The /etc/passwd file contains user account information that is used by many system utilities and therefore must be readable for these utilities to operate.
Rationale:
It is critical to ensure that the /etc/passwd file is protected from unauthorized write access. Although it is protected by default, the file permissions could be changed either inadvertently or through malicious actions.
Fix:
Run the following commands to set permissions on /etc/passwd- : # chown root:root /etc/passwd- # chmod u-x g-rwx,o-rwx /etc/passwd-
Parameter:
[110000000, 0, 0]
Technical Mechanism:
Run the following commands to set permissions on /etc/passwd- : # chown root:root /etc/passwd- # chmod u-x,go-rwx /etc/passwd-
