It applies to both, and even repeatedly if you attack and/or defend multiple times in a round. It doesn't say anything like "once per round", and doesn't expend any resources, so you cab use it as often as it triggers.

Lone wolf is one of those upgrades that's fantastic if you can keep a ship alone most of the time, because it improves every attack and defense roll they make. This is great, for example, when you're facing lots of foes that want to focus-fire you, or when you can fire repeatedly (Twin Laser Turret, Gunner, TIE/d, etc).
