Below may be considered an example of how to setup a regular (daily) verification of the system configuration. The actual frequency you use might differ. The keyword in the recommendation is: regular. Further, the example also shows two syslog reporting lines: one to a system file, the second to a centralized syslog service. The second entry is added as a comment because the hostname is likely not correct and/or there is not a centralized syslog server. The syslog facility local1 is used to keep these reports out of the standard syslog facilities. There is not meant to establish a requirement to use facility local1. An alternate facility can be used as per site policy. Ensure that the log directory and file exist # /usr/bin/mkdir -p /var/log/syslog # /usr/bin/touch /var/log/syslog/inventory.log If logging for local1.info events is not already configured add this to the syslog configuration: #!/usr/bin/ksh /usr/bin/egrep "^local1.info /var/log/syslog/inventory.log" /etc/syslog.conf >/dev/null if [ $? != 0 ]; then print "local1.info /var/log/syslog/inventory.log rotate time 1d files 30 compress" >> /etc/syslog.conf refresh -s syslogd || startsrc -s syslogd ... (see CIS section 2.1)
