SV-35206r2_rule The system's access control program must log each system’s access attempt.

Vulnerability discussion

If access attempts are not logged, then multiple attempts to log on to the system by an unauthorized user may go undetected.

Check content

Normally, tcpd logs to the mail facility in the syslog.conf file (normally located within the /etc directory). Determine if syslog is configured to log events by tcpd. # find /etc -type f -name syslog.conf # cat /syslog.conf | tr '\011' ' ' | tr -s ' ' | sed -e 's/^[ \t]*//' |grep -v “^#” | egrep “mail.debug|mail.info|mail.\*” Look for an entry similar to the following, indicating that mail alerts are being logged: mail.* /var/log/maillog If no entries for mail exist, then tcpd is not logging and this is a finding.

Fix text

Configure the access restriction program to log every access attempt. Ensure the implementation instructions for TCP_WRAPPERS are followed so logging of system access attempts is logged into the system log files. If an alternate application is used, it must support this function.

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.
