"This is just too easy..."

After seeing the movie thrice (and reading the book the same number of
times) it began to bother me that the spells protecting the sorcerer's
stone were so easy to defeat.  If you're really trying to keep the
stone away from Voldemort, would you set up spells that first-year
students can defeat?

If this topic has been hashed out before, can someone either point me
to the discussion (no idea what term to use for a search) or let me
know what the consensus appears to be?  Thanks.
