Security updates

[slimmy baddog]

Hallo.

I am new to FreeBSD and i wanted to ask something since systems security is 
what interests me the most.

Does freebsd have an automated update system like redhat has ?

Also where can i find a list with patches for all local - remote holes and 
bugs of FreeBSD 4.9 ?

Thank you very much for your time !

Best Regards
A. Stamatis
