CERT typically ignores requests for help unless you are a very large
company. Small ISP's and businesses connected to the internet are unlikely
to receive personal assistance.
However, CERT has put out an advisory on the qpopper vulnerability:
>From the vendor information page:
"Versions of QUALCOMM qpopper prior to 2.5 are vulnerable. QUALCOMM
recommends upgrading to the most recent version..."
CERT also has a paper on recovering from incidents which is accessable
from their web page and ftp site.
And finally, two other sites you should keep an eye on:
http://www.freebsd.org/security/security.html (FreeBSD Security Guide)
http://www.watson.org/fbsd-hardening/ (FreeBSD Hardening Project)
