Vulnerability discussion

Monitoring and recording successful and unsuccessful logins assists 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. # last -f /etc/security/failedlogin | more If the commands do not return successful and unsuccessful logins, this is a finding.

Fix text

Edit /etc/syslog.conf and add local log destinations for auth.* or both auth.notice and auth.info. "auth.info /var/log/authlog" Verify service startup scripts for syslog and utmp (if present) are enabled. # vi /etc/rc.tcpip Check the syslogd service is not commented out. Refresh syslogd. #refresh -s syslogd

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.
