Discussion

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

Verify /etc/hosts has no extended ACL. # ls -lL /etc/hosts If the permissions include a "+", the file has an extended ACL, this is a finding.

Fix Text

Remove the optional ACL from the file. # chacl -z /etc/hosts
