Which of the following names represents inbound filtering?

Show Suggested Answer Hide Answer
Suggested Answer: D

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.

Egress? Really? That sounds more like outbound filtering to me. I'm going with Ingress on this one.

Ingress, for sure. The name just screams 'incoming traffic control' to me. Easy peasy.

Hmm, I'm pretty sure inbound filtering is represented by 'Ingress'. That's the one that sounds the most like it's filtering stuff coming in, you know?
