Check: GEN001368

SUSE Linux Enterprise Server v11 for System z STIG: GEN001368 (in versions v1 r12 through v1 r9)

Title

The /etc/hosts file must have mode 0644 or less permissive. (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 mode of the /etc/hosts file. # ls -l /etc/hosts If the file mode is not 0644, this is a finding.

Fix Text

Change the mode of the /etc/hosts file to 0644. # chmod 0644 /etc/hosts
