Securing Truck Bed Bars and Cargo Basket

So as a new owner of a Nissan Frontier, instead of the truck bed cover, I opted to getting truck bed bars and a basket to add on top of the bars for when we go camping it adds an extra cargo layer. I noticed when I was installing it that its pretty much tightened with clamps, there are no bolts or screws or any other security measure.My question is, how do most people keep it from getting stolen? Besides keeping it in your garage, what can/do you do to keep someone from removing the bars and basket from your truck? This is pretty much my setup minus the toolbox.
