Check content

Depending on what system is used for log processing either /etc/syslog.conf or /etc/rsyslog.conf will be the logging configuration file. Check /etc/syslog.conf or /etc/rsyslog.conf and verify the authpriv facility is logging both the "notice" and "info" priority messages. Procedure: For a given action all messages of a higher severity or "priority" are logged. The three lowest priorities in ascending order are "debug", "info" and "notice". A priority of "info" will include "notice". A priority of "debug" includes both "info" and "notice". Enter/Input for syslog: # grep "authpriv.debug" /etc/syslog.conf # grep "authpriv.info" /etc/syslog.conf # grep "authpriv\.\*" /etc/syslog.conf Enter/Input for rsyslog: # grep "authpriv.debug" /etc/rsyslog.conf # grep "authpriv.info" /etc/rsyslog.conf # grep "authpriv\.\*" /etc/rsyslog.conf If an "authpriv.*", "authpriv.debug", or "authpriv.info" entry is not found, this is a finding.

Fix text

Edit /etc/syslog.conf or /etc/rsyslog.conf and add local log destinations for "authpriv.*", "authpriv.debug" or "authpriv.info".

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.
