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.

Funnel sounds more like a marketing term, not filtering.

I practiced a similar question, and I think "Funnel" might be a trick option. I’m leaning towards "Ingress" too.

I feel like "Egress" is related to outbound traffic, so that can't be it. I think "Ingress" is the best choice.

I remember studying about filtering types, but I'm not entirely sure if "Sanity" is the right term for inbound filtering.

I think inbound filtering has something to do with traffic coming into a network, so maybe it's "Ingress"?

I think the answer is Ingress. That term sounds like it's referring to traffic coming into the network, which is what inbound filtering is all about.

I'm not totally sure about this one. I'll need to review my notes on network security concepts to make sure I understand the difference between these terms.

Okay, let's see. Inbound filtering is about controlling what comes into a network, so I'm guessing the answer is either Ingress or Funnel.

Sanity? That's just asking for trouble. I'm pretty sure the correct answer involves something more technical-sounding, like Ingress.

Ingress is the way to go. Unless you're trying to be fancy and call it 'the great filter of doom', in which case I guess Funnel would work too.

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?
