It depends. There are vulnerabilities in kernel and userland fixed
between 7.0-RELEASE and 7.2-RELEASE-p2. See
http://security.freebsd.org/advisories.html If any of these
vulneratbilities affect your system you should see if there are
workarounds mentioned. If not it would be best to upgrade. 

If you subscribe tot the freebsd-announce mailing-list, you'll be warned
when a vulnerability is found. You can then judge if it is wise to apply
the fix.

In general, I would follow the minor version branch (RELENG_7_X,
7.2-RELEASE-pX) to pick up fixes for vulnerabilities.
