Your flop bet will fold the field almost never and your hand is still very vulnerable as anyone that calls likely has 6 outs against you. The only way to protect your hand here is to go for a check/raise.

You are right that about 50% of the time the preflop raiser has just overcards so the best play is to check to him so he'll bet hopefully folding the blinds and then raise. This will force the players between you to call 2 bets cold (which they may do but they will not have the odds to do so). If he bets and gets several callers you need to figure out how many outs you have in determining whether to continue or not (I would call or fold though). You may have odds as you have a few backdoor draws (any 2,4,7,8 improves your hand and a 6 drastically improves it). Probably 3-4 outs total.

You could also call his flop bet and go for a check/raise on the turn if a blank fell, depending on how likely he is to continue on a bluff and how many people are left in the hand.
