SV-39832r2_rule System log files must have mode 0640 or less permissive.

Vulnerability discussion

If the system log files are not protected, unauthorized users could change the logged data, eliminating its forensic value.

Check content

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.

Fix text

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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
