Which of the following names represents inbound filtering?

Ingress filtering is a method used in network security to ensure that incoming packets are allowed or blocked based on a set of security rules.

This type of filtering is often implemented at the boundaries of networks to prevent unwanted or harmful traffic from entering a more secure internal network.

The term "ingress" refers to traffic that is entering a network boundary, whereas "egress" refers to traffic exiting a network.
