Vulnerability discussion

Monitoring and recording successful and unsuccessful logins assist in tracking unauthorized access to the system. Without this logging, the ability to track unauthorized activity to specific user accounts may be diminished.

Check content

Determine if successful logons are being logged. # last | more Determine if unsuccessful logons are being logged. # more /var/adm/loginlog If the commands do not return successful and unsuccessful logins, this is a finding. Check the syslog daemon configuration for authentication logging. # egrep "auth\.(info|debug)" /etc/syslog.conf If there are no entries in syslog for the auth service, this is a finding.

Fix text

Verify that login logs are handled correctly in the /etc/syslog.conf file. Edit the /etc/syslog.conf file and add one of the entries below. auth.debug /var/log/authlog OR auth.* /var/log/authlog Verify that service startup scripts for syslog and utmp (if present) are enabled.

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.
