# Rule Configuration Reference

For each custom rule that you create, you can configure one or more conditions with [**parameters**](#parameters) from the incoming traffic that you compare with specific values using [**operators**](#operators). For each new condition, you can choose how you combine it with the previous condition using the **AND** (Both conditions need to be met) or the **OR** operator (One of the conditions need to be met).
