Destiny uses a mix of client/server and p2p (Destiny)

I'd think at this point we really don't know how Destiny would respond to memory hacks. There's at least a chance that if you could change your 335 Light level to 777 the other clients might just accept it and make you invincible in Iron Banner. Maybe you could set your heavy ammo from 0 to 100 rockets and Destiny wouldn't complain. This is where it's very nice to not be playing on a PC.

On the other hand, we can already see that Destiny doesn't put complete trust in the clients. We've all seen a heavy ammo box get delayed in opening because of lag. You hold down the button for the right amount of time but your Destiny client doesn't have absolute say on when the heavy ammo gets distributed. Sounds like in The Division it would.
