Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium for firewall policies with improved efficiency. A policy can be defined that specifies a set of firewall rules, where the set of firewall rules provides a respective firewall rule for each layer of a plurality of layers within a hierarchical structure of a network, the network including a plurality of elements. Determining, for a first element within the network, a position within a first layer of the hierarchical structure. In response to receiving a data transmission request to or from the first element, applying the set of firewall rules in accordance with the first layer of the hierarchical structure, where applying the set of firewall rules comprises sequentially applying each respective firewall rule at each layer from an upper layer within the network to the first layer within the network.
