Check: GEN001367

HP-UX 11.31 STIG: GEN001367 (in versions v1 r19 through v1 r13)

Title

The /etc/hosts file must be group-owned by root, bin, sys, or system. (Cat II impact)

Discussion

The /etc/hosts file (or equivalent) configures local host name to IP address mappings that typically take precedence over DNS resolution. If this file is maliciously modified, it could cause the failure or compromise of security functions requiring name resolution, which may include time synchronization, centralized authentication, and remote system logging.

Check Content

Check the /etc/hosts file's group ownership. Procedure: # ls -lL /etc/hosts If the file is not group-owned by root, bin, sys, or other, this is a finding.

Fix Text

Change the group owner of the /etc/hosts file to root, sys, bin, or other. Procedure: # chgrp root /etc/hosts
