FreeBSD 10: Apply Binary Updates To Keep Base System Up To Date

I know keeping a FreeBSD server up to date is a very important. How can I apply binary system patches and updates to a new installation of FreeBSD 10 server?

You need to use the freebsd-update tool. It is used to fetch, install, and rollback binary updates to the FreeBSD base system.

Find out current FreeBSD release

Type the following command:
uname -mrs

OR

uname -a

Sample outputs:

FreeBSD netbook02 10.0-RELEASE FreeBSD 10.0-RELEASE #0 r260789: Thu Jan 16 22:34:59 UTC 2014     root@snap.freebsd.org:/usr/obj/usr/src/sys/GENERIC  amd64

FreeBSD install security updates and patch the server

Type the following command on a newly installed FreeBSD server:
# freebsd-update fetch install
Sample outputs:
