Portaudit is intended to run daily against your ports directory identifying known vulnerabilities against a central database. Each night it produce an email that gets sent out and requires inspection.
The problem with this is with many FreeBSD hosts the emails can just be too many and I tend not to look at them.
Portaudit Central provides a means for delivering portaudit output to a central email box which will then produce a simple HTML based report of all machines.
This package consists of 3 scripts written in perl: portaudit-receive.pl, portaudit-report.pl and portaudit-send.pl there is also a simple configuration file, just a bit of perl declaring variables.
