The talented 22-year-old could come up against Chelsea's spot-kick expert when the Bees take on the FA Cup holders in the fourth round on Sunday.
Moore limbered up for the showdown by saving a penalty in Tuesday night's 2-2 draw with Leyton Orient and says he will be just as confident if he has to face Lampard from 12 yards.
"The thing with Lampard is, he's a fantastic penalty taker but if he steps up I'll have every confidence of saving it," said Moore.
"You have to look at how penalty takers take them. On the day they might change their mind but if you have a look at the information then you've got every chance.
"He puts it left, he puts it right, he puts it down the middle, he puts it all over the place. It's the sign of a good penalty taker because he mixes it up. But come Sunday I'll have every confidence of saving one."
