There are no new protections for accredited investors. To be accredited you need to either have over $1m in net worth (excluding your primary residence) or have earned an income of $200k/yr as an individual (or $300k/yr as a joint couple) for the past two years. The philosophy here is and has been: if you're wealthy then you can probably take care of yourself.

The last remaining piece of the JOBS act is Title III, the part that allows non-accredited investors to invest. There are protections for this class of investors, including income-based limits (you can't invest more than 5%-10% of your income a year) and it requires investments to be made through a crowd on a crowdinvesting platform. The SEC is still working on the exact rules and regulations for this.
