updated packages for security issues on FTP server?

[Jeremy C. Reed]

What is the policy or procedure for FreeBSD ports team (or maintainers) to 
provide updated packages (prebuilt .tbz) for security issues for the FTP 
servers?

If this is documented, please point me to it.

I have seen past security advisories for "ports" that have pointed to 
prebuilt packages on the FTP server.

But looking today at 
ftp://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-6-stable/ I don't 
see any new packages within a month (although ports tree has been updated 
for security issues).

Where would packages for security fixes be uploaded to?
