Defense, yes, so far as your overall skill in light and/or heavy armor improves, but that's not dependent upon leveling up. You could be capped with heavy armor of 91 but still see your Armor stat increase as you approach 100. You just won't be able to get any more perks.
Attack appears to be your weapon's stats + perks + condition (fine, superior...epic, etc)
