You only need to sync and rebuild when a security problem is announced
via that mailing list.

Install ports-mgmt/portaudit and run it daily (I believe it installs
so that it will email you daily results as part of periodic) and when
it tells you that one of your installed ports is out of date, take
care of it.
There's no "schedule". Because, despite what MS would have PHB's believe,
security problems are not found on any schedule, they're found whenever
Thus, your best approach is to monitor and be proactive.
