The /etc/hosts.allow file contains networking information that is used by many applications and therefore must be readable for these applications to operate.
Rationale:
It is critical to ensure that the /etc/hosts.allow 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.
Parameter:
[permission 644]
Technical Mechanism:
If the permissions of the /etc/hosts.allow file are incorrect, run the following command to correct them:
# /bin/chmod 644 /etc/hosts.allow
