Title

The system's access control program must log each system access attempt. (Cat II impact)

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 /etc/syslog.conf. Determine if syslog is configured to log events by TCPD. Procedure: # cat /etc/syslog.conf Look for entries similar to the following: mail.debug /var/adm/maillog mail.none /var/adm/maillog mail.* /var/log/mail auth.info /var/log/messages The above entries would indicate mail alerts are being logged. 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 system access attempts are logged into the system log files. If an alternate application is used, it must support this function.
