Check the mode of log file hierarchies. Procedure: # ls -lLRa /var/log /var/adm If any of the log files or their directories have modes more permissive than "0640", and these are not documented, this is a finding.
Change the mode of the system log file(s) to 0640 or less permissive. Procedure: # chmod "0640" /path/to/system-log-file NOTE: Do not confuse system log files with audit logs. Any subsystems that require less stringent permissions must be documented.
